A firm family favourite, strawberries are easy to grow and don’t take up much room. Why pay high prices at the supermarket when you can enjoy your own home-grown sun ripened berries at home all summer long? Pick a spot that is full sun and has good drainage. A large pot is a good option but remember to water it regularly! When it comes to choosing varieties, older varieties such as Camarosa and Pajaro are ‘short day’, meaning they need a certain number of daylight hours to initiate fruiting. This meant fruiting occurs for a limited period, usually around November - December. Many modern varieties (Albion, Seascape etc) are day-length neutral and fruit over a longer period. Essentially, if temperatures are high enough for fruit to ripen, they will fruit. It is a good idea to plant a combination of both types to get as long a harvest as possible. Strawberries hit peak production at about 3 years old and after that fruiting starts to lessen. Ideally you will have a replacement strategy where you plant younger plants in the 3rd year to replace the older plants and keep fruiting at maximum output. You can do this by buying new plants or potting up runners off the existing plants. Runners are little leaflets that are attached to the main plant by a longer than normal stem. If you pin the leaflet to the ground while it is still attached to the plant, it will form roots at which point you can cut the stem to the mother plant leaving you with a new plant. Runners are a great budget friendly way to increase your number of plants but try and swap some with a friend to ensure some genetic diversity in your plants. If you want to ensure plenty of fruit to enjoy each summer, plant 5 (or more!) plants per person in your household. Producing fruit takes up a lot of energy so make sure that you feed your strawberries with a berry fertiliser at planting time and side dress several times during the growing season. Give them an energy boost regularly while they’re producing berries with a liquid fertiliser that has a high ‘K’ number in the NPK rating on the bottle. ‘K’ is potassium which supports flower and fruit development. Do this every 7-14 days for lots of big, juicy, sweet fruit. Protect your crop! Cover them with bird netting, pin the edges down securely and make sure there are no gaps or they’ll find a way in, or a Net Tunnel or cloche! Make sure you have some cloche hoops or stakes to ensure the birds can’t bounce on the netting and reach the berries through the netting. Trust me – they are clever and determined! When watering, try and water the soil as gently as possible and avoid getting it on the leaves if possible. Water on the leaves increases humidity which creates perfect conditions for fungal diseases to thrive. A weeper hose is a good option to use. If possible, in the garden, plant them up on a mound to ensure good drainage and surround the plants with some pea straw or other mulch to keep the soil moisture in and to keep the berries out of contact with the soil. Give them a preventative spray with a copper spray a few times through spring when humidity is higher to help prevent any fungal diseases getting established. Plant your own strawberries and enjoy the flavour of sun ripened, delicious, sweet berries. It's a great way to get kids and grandkids involved the garden, picking and eating them!

Dahlias have certainly come full circle after falling from grace from the 60’s - 90’s during the rise of formal and then minimalistic garden design. There was no room in the garden for these bright, exuberant blooms. Over the last decade they have crept back into fashion with social media, in particular Instagram and the rise of home flower farmers bringing the gorgeous blooms to our attention causing their popularity to skyrocket over the last view years. Dahlias have grown so popular they have been compared to Holland’s ‘Tulipmania’ in the 1700’s. They certainly deserve their time in the sun. Dahlias have wonderful range of shapes, sizes and colours. From dinner plate sized in vibrant hues through to tiny pom poms in delicate pastel, there is something for everyone’s taste. They repeat bloom from mid-summer through to mid-autumn. They are straight-forward to care for and they look stunning, in the garden, as cut flowers, dried on a wreath or in a display. You should consider the space in your garden when choosing your varieties. The dinner plate varieties take up quite a bit of space and the weight of the sizeable blooms, have a tendency to flop if not securely staked. The cactus and decorative varieties while smaller in flower can also take up a lot of real estate in your border and they can be quite tall. If the position is not sheltered from wind, staking is highly recommended. If space is limited or you’re planting in pots consider the pompom, gallery, anemone or collarette varieties that tend to be smaller in plant size and bloom size. A dahlia grows from a tuber in the ground. It dies down completely in winter and resprouts in spring. To avoid the tuber rotting if your soil is heavy and wet over winter, it is highly recommended that you lift the tuber after it dies down and you store it in a cool, frost free spot over winter. Replant in the spring. If the tuber is in well drained soil or a raised bed, you can leave it in place but ensure it is well protected from frosts with a thick layer of compost or mulch. Lifting the dahlia tuber does give you the opportunity to inspect for damage, or to divide the tuber into multiple new plants. You simply need to ensure that there is an ‘eye’ or sprout on the section of tuber you are going to divide off. There are usually multiple eyes on a tuber. This is a great way to increase the number of plants you have or to share different varieties between friends. Alternatively, you can purchase specific named dahlia varieties from a garden centre in mid winter. How to get the best performance out of your dahlias? Feed them well with a bulb food when they are beginning to sprout and after they finish flowering and start to die down. This will give the plant a boost to start its season and to help the plant store food in its tuber at the end of the season. Once it is in full growth, feed with a fertiliser for flowers such as rose fertiliser or one with a high balanced nitrogen and potassium levels on the NPK rating. This is to support plenty of blooms. Remember to deadhead the finished blooms to encourage the plant to flower again during the season. In terms of pests and diseases, there are a few to keep your eye out for. Regularly checking in on your dahlias is key to putting a stop to any problems before they become a real issue. As soon as you see the first sign- do something about it! Physically remove the insect or affected part of the plant to slow the spread or stop it completely. Follow up with an appropriate spray. Slugs and snails will make fast work of the new shoots so ensure you spread some bait around to protect them in early spring. If you head out at night with a torch you will catch them in the act! If the petals are ragged, earwigs are probably to blame or if there are holes in the centre of the dahlia and petals but no slime trails, take a closer look and you’ll spot a very hungry caterpillar munching away. Removal is the easiest control for caterpillars, otherwise apply a spray that controls caterpillars. Earwigs are harder to control, they are nocturnal and they like to hide so remove any potential hiding places and provide one with a damp rolled up newpaper tied with string that you can get rid of them from daily . Mites and thrips can be an issue at times, thrips cause a light flecking on the petals, mites are hard to see but cause a mottling on the leaves. Grosafe BioNeem or Groventive will provide control for these. The disease that can be a common occurence on dahlia leaves, especially in warm humid weather is powdery mildew. Silver powdery blotches on the leaf surface that can spread quickly if left untreated. Removal of the affected leaves at first sight is the best control/prevention. If it has started to spread, Grosafe Enspray 99 is effective at smothering spores on contact so thoroughly spray the foliage. You will need to repeat if it appears again. Good airflow through the plant is helpful in prevention so you may need to thin out some foliage if the plant is particularly crowded. Watering the soil and not the foliage will also help prevent it. Dahlias are a wonderful addition to your garden, with plenty of colours, shapes and sizes to choose from. Whether they are colour for the garden or for picking to enjoy inside, they will bring you much pleasure. Written for Gubba by Kelly Jean Reyland from Garden Advice NZ (www.gardenadvice.co.nz)
Winter is the ideal time to carry out a clean sweep, and get on top of any lingering insects or fungal spores from the previous growing season. They can hide in cracks, in plain sight on the stems or in the fallen leaves around the base of the plant. They go dormant, waiting for warmer weather and the chance to make a comeback next spring. Start with the basics: Collect the fallen leaves from around the base of any plant affected by fungal disease or insect during the growing season. Spores and eggs can remain on leaves so if you get rid of these, part of the battle is already won. Ensure that you throw them in the bin or burn them. You don’t want to put them in the compost bin. Home compost rarely gets hot enough to kill off fungal spores. You don’t need to collect up every fallen leaf on your property, just the affected ones. What sprays do you use for a winter clean up? A copper based fungicide is used to clean up spores and create a protective layer over any cuts or wounds on the tree and a spraying oil insecticide smothers any scale insects present on stems, or insect eggs present on the plant. These were traditionally combined and applied together but the current recommendation is to apply them separately, waiting 1 week between applications. Not all sprays are created equal. Copper hydroxide (sold as ‘FreeFlo copper’) has the smallest copper particle size which gives it increased coverage, rain fastness and longevity. That equals better protection and disease control for your plants compared to other copper sprays on the market. Among the available oil insecticides, Enspray 99 oil stands out for having the smallest particle size which again improves coverage and control of pests. The improved coverage also gives it the added ability to smother powdery mildew spores. The 99 in the name refers to it being 99% pure of impurities which significantly minimises the risk of burning when applied. A lesser used winter spray is lime sulfur. As a winter spray and at winter application rates, it is generally only used on deciduous plants as it will cause defoliation (leaf drop). It is useful to help force deciduous plants that are slow to drop their leaves into dormancy and it cleans up lichen off stems and controls scale, mites and fungal diseases. It is effective but it is messy, and you have to be very careful with its application and minimise spray drift onto surrounding evergreen plants that can be burnt. It is really important to note that this spray can’t be used within two weeks of copper or oil sprays. When do you carry out winter clean up sprays? Ideally at the end of autumn, when the trees have dropped their leaves, copper and oil sprays are good to seal all the tiny entry points into the tree, created by the dropping leaves. They protect against fungal disease and clean up any pests that are still present. Follow up with another application later in winter before the spring growth starts. For roses, spray after pruning has been carried out in approx July (If they refuse to drop their leaves, lime sulfur can be applied at least two weeks before pruning and spraying with copper/oil, forcing them to drop their leaves and go dormant). Do another follow up application of copper/oil before spring growth starts. For fruit trees - especially peaches and nectarines that have had leaf curl - Spray with copper at bud swell and repeat 14 days later. Prevention is such an important step in keeping our plants healthy and thriving. Winter clean up sprays are an important step in this process. Remember - ‘A pinch of prevention is worth a pound of cure!’ Shop Garden SprayersShop Weed & Pest Control Written for Gubba by Kelly Jean Reyland from Garden Advice NZ (www.gardenadvice.co.nz)
Hydrangeas are the shrub that can always be relied upon to put on a good show in part – full shade positions. In the past we were limited to the standard ‘mop top’ or ‘lace cap’ varieties but we now have more varieties available to us such as Oakleaf, Panicle, Smooth and climbing options. It is important to correctly identify what variety of Hydrangea you are pruning. This will guide you how and when to prune your variety correctly as different varieties are pruned at different times and if you get it wrong, you may miss out on blooms that year. First things first; when pruning always start by removing any branches that are dead, damaged or diseased branches. Bigleaf Hydrangeas ‘Mop top’ flowers (Bridal Bouquet’, ‘Raspberry Crush’ etc. ) and serrata with ‘lace cap’ flowers ‘Blue Deckle’ and “Libelle’ are some of the cultivars available. Flower buds form the previous growing season, at or near the ends of the branches – easily recognisable as ‘two fat buds’ on the stems in late winter. If you cut back beyond them, you will forfeit your blooms for the upcoming summer. In areas with harsh winters, leave the old flower heads on the bush to protect the fat buds from the winter cold. Prune in spring, cutting the stems back to just above the ‘two fat buds’. If you need to bring the height of the bush down, you will need to prune in late summer well before next years flower buds have formed on the stems. You may have to sacrifice some blooms to make the cuts. If the bush is getting crowded, thin out some of the excess twiggy branches to let air and light into the bush. Oakleaf Hydrangeas ‘Pee wee’ and ‘Snowflake’ are some of the cultivars available. Grown for their stunning large red, oakleaf shaped leaves as much as the white panicle flowers. Prune the same way as the bigleaf hydrangeas back to ‘two fat buds’ unless you are more interested in the foliage, in which case cut the stems back one quarter in late spring to stimulate leafy growth and forfeit the flowers. Panicle Hydrangeas ‘Limelight’, ‘Candlelight’ and ‘Bombshell’ are some cultivars available.These varieties bloom on new seasons growth so prune in late winter-early spring, between the last heavy frosts and before it starts to shoot new growth. The buds should be swelling so you can tell if any have died during the winter and need removing. Cut back each stem by about one third, to just above a ‘node’ - where the buds swell and form. Trim out any weak, wispy growth to focus the plants energy into the bigger branches for a stronger plant and better show of blooms. Smooth Hydrangeas Such as ‘Annabelle’. These also flower on new seasons growth, so follow the steps for pruning panicle hydrangeas above. Climbing Hydrangeas ‘Petiolaris’ climbs by attaching itself onto a support structure or wall. Prune in early spring before growth begins. Cut back overly vigorous branches and shorten flowering stems that are growing outwards from the support structure. The vine flowers on new shoots so light pruning to stimulate growth is beneficial for more blooms. Pruning your hydrangeas will encourage blooms and improve the health of the plant by removing dead or diseased branches. It will enable you to control the overall shape and size of the plant, keeping it happy and healthy.

One job that we should never brush off as unimportant - particularly for fruiting plants and trees - is pruning. Why do we prune? We prune for health, for size, for beauty, for harvest and for pleasure. So yes, it’s quite important! In this blog we look at berry fruit specifically. At the very basic level, pruning lets in air and light and removes dead, dying or diseased branches. This helps improve the overall health of the plant and reduces the chance of diseases. Anyone who has seen an ignored raspberry bush will understand how crowded they can become, and we have all seen blackberries and brambles smothering other plants on the side of the road, left to their own devices. More specifically for fruiting plants, pruning helps to remove branches that will no longer fruit and are simply diverting energy from fruit production. It enables us to control the number of fruit (thinning) which improves the size and sweetness of the remaining fruit. Removing excess stems and branches also enables the maximum amount of sunlight into the plant or tree which is converted into food for the plant. The vital piece of information you need before pruning your berry plant is what year wood does the plant produce its fruit on. What does that mean? - First year wood means the fruit will only develop on new growth from this spring, e.g. blueberries, double fruiting / everbearing raspberries - summer harvest - Second year wood means the fruit will develop on wood that grew last spring, e.g. blackberries / brambles, currants, black currants, raspberries - single harvest, double fruiting (everbearing) raspberries – fall harvest - Third year wood means the fruit will develop on wood that grew in spring two years ago, e.g. currants Pruning It’s pruning time (after you make sure your secateurs are sharp and clean!). It's good practice to start by removing the 3 D’s: dead, dying or diseased. This will simplify your job going forward... Blackberries/brambles - Fruiting on second year wood, the long canes will die after fruiting, leaving a strong bud at the base of the dead cane or a completely new shoot from the base. Cut the cane back to the bud or remove completely if there is a new shoot from the base. Do this when they are dormant. Also remove excess new canes, leaving only six or so of the sturdiest and healthiest canes. Grow them against a support frame to enable control of the shape, enable easy pruning and easily access the fruit. Shorten the new canes to encourage side shoots which will fruit next spring. To help make pruning simple, you can train the first-year canes (next year's fruiting canes) in one direction along a trellis and have the fruiting canes trained in the other direction. At the end of the fruiting season, you can remove all those fruited canes, leaving room for the new canes. Blueberries - Fruiting on first year wood, in the first three years, the only pruning they need is removing dead and diseased wood. Highbush varieties will keep growing new stems / branches for 6 years, so the first step is to remove any stems more than six years old. After that trim back young or spindly stems to strong branches or buds and remove older twiggy growth. Rabbiteye varieties are more vigorous growers than high bush so prune them similarly but don’t cut them back too hard to avoid stimulating excessive growth. Black currants - They bear their best fruit on second year wood so when they are dormant remove the stems that have fruited, right to the ground or to a low, strong side shoot that will grow a new stem. Thin out one-year stems to the ground, leaving just 6 of the strongest, upright stems, to avoid crowding. Raspberries (single harvest varieties) - Simply remove the canes that fruited this season and leave the new canes to fruit next season. You can usually see where the berries have been attached or by the colour. The canes to remove are matte brown/grey. The canes to leave are green/brown. Double harvest varieties - These fruit at the tips of first year canes in late summer and autumn. These same canes will fruit the following season in early summer lower down the cane. You can remove the tips after they fruit the first time, leaving the lower cane to fruit again. After the second harvest lower down on the canes, remove the entire cane from the base. Leave the first-year canes. There are few foods that compare to the taste of homegrown, sun-ripened berries. Grow your own and as you learn how to care for them you will enjoy many years of delicious berries! Written for Gubba by Kelly Jean Reyland from Garden Advice NZ (www.gardenadvice.co.nz)
A well-kept lawn looks great and helps the surrounding area look better. And one of the ways to help your lawn look its best is to keep it weed free! One of the best pieces of advice you can take regarding weeds (also pests and diseases) is to deal with the issue when you first see it. The issue will only get worse with time; that's pretty much a guarantee! So, when you first see that patch of creeping oxalis, the prickly seed heads of onehunga weed or the distinctive rosette pattern of cape daisy leaves, do something about it. It might be just removing flower heads or seed heads so it can’t spread while you deal with the leaves and roots. Or it might be getting straight out there with some weedkiller to knock it dead. Don’t leave it there to spread and become a bigger problem! Follow this up by keeping the lawn well fed so it is thick and can easily compete with any weed seeds that attempt to germinate, and finally mow your lawn on a high setting, so the lawn is dense and helps prevent weed seeds finding a spot to germinate. Weed control Some weeds are easy enough to remove manually. The cape daisy is a good example. As long as the soil is moist, you can use a daisy remover to gently lever the entire long tap root out of the ground and in one go remove the entire plant. It makes sense to do so when you learn that all the little fragments of each cape daisy leaf created and spread by being run over with the lawn mower can grow into an individual plant. When a weed has appeared in the lawn in a small, isolated position, it is effective to carefully spot apply a non-selective weedkiller and once the weed is dead, resow the patch with grass seed. Once a weed has spread through the lawn, the most effective way to get on top of the issue is applying a selective lawn weed spray that is appropriate for the specific weed. Ensure that you follow the instructions for how much to apply to how many square metres of ground to avoid burning the grass. Be aware that most selective lawn sprays are hormone based which work by disrupting cell division or disrupting photosynthesis. It is really important that you don’t put the lawn clippings in the compost or as mulch around existing plants as the hormone will reside in the material for months to come and will affect other plants negatively e.g., putting the compost containing the broken down clippings on your vegetable garden or around your roses and the plants failing to grow or thrive with rolled up, curled leaves. It will state on the instructions how long the clippings need to be put in the rubbish before it is safe to resume doing so. You also need to be aware of the surrounding gardens when you apply the spray. A broadleaf weed spray will work on a ‘weed’ or a broadleaf plant, so you need to be very careful with spray drift. It is good practice to hose off any particularly special or important plants if there is any risk of spray drift after spraying. You also need to consider where trees and shrubs overhang the lawn as their roots will come into contact with the spray and it can knock them back in their growth. Weedkillers fall into two groups – selective and non-selective. Lawn spray is an example of selective where it will kill off broadleaf plants but not the blades of grass when applied at the correct application rates. Glyphosate is an example of non-selective where it will kill off anything it comes into contact with. Unfortunately, any grass weeds such as paspalum or twitch/cooch can’t be controlled by selective weedkillers as they are a grass rather than a broadleaf. They need to be controlled with careful application of nonselective weedkiller. Some professional lawn care companies do have sprays that control certain weed grasses in a lawn, but they are not available to buy off the shelf for home gardeners. If grass weeds are widespread in the lawn, getting a quote from a lawn company could be the most cost-effective way to get it under control. Within the non-selective group there are also contact and systemic sprays. Contact sprays will burn off the tops but leave the roots intact. Natural oil or fatty acid style sprays fall in this category. They are effective for very young weeds without established root systems but established perennial weeds will simply grow back from the roots. Systemic sprays will be absorbed through the leaves into the sap system and travel back through the roots killing off the entire plants. This is a much more effective method with established perennial weeds. Moss in the lawn Moss can be caused by several environmental factors. Poor drainage / excessive water, too much shade, soil pH being too acidic or poor soil fertility. These are things that should be addressed as well as treating the moss growth. If you don’t treat the cause of the issue, the moss will simply grow back. Poor drainage or excess water can be improved by adding gypsum to help improve soil structure or adding drainage to the area. In a shady area, you can look at a shady lawn blend which is better suited to the area or look at an alternative to lawn for ground cover. Acid soil pH can be addressed by regular application of lime and altering the soil pH can make nutrients in the soil more available for the plant to access and use. Lawn fertiliser with added iron sulphate will add nutrients to the soil and help control moss growth. Be careful not to get it on hard surfaces as iron sulphate will stain them. Maintain your lawn's good looks by keeping weed and moss growth under control. In combination with regular feeding and care it will be an asset to your property.

Autumn is a prime time to get your lawn looking its best. There is still warmth in the air and soil and there is moisture available in the soil for optimal growing conditions. If you are looking to sow a new lawn, now is the time! Get your seed spread as soon as possible before the winter cold halts growth. Smooth out the soil so you have an even surface and remove any weeds. Your preparation now will affect the finished lawn. If you have time to leave the soil bare so any weeds seeds germinate and you can spray them off and remove them, do so. This helps to ensure your lawn will have less weeds competing with your lawn seed as it starts to grow. If you can repeat that process a few times it will be an even better final result, but you do need to get that seed growing so be as fast as you can with winter approaching. If your soil is very sandy or heavy, spreading a layer of lawn soil is a good base to get the seeds started. You buy it bagged, it is weed free, has water holding crystals to help maintain an even soil moisture while seeds germinate, and it has some appropriate fertiliser. If you have an existing lawn and you have shallow dips that you need filled in to even out your lawn, lawn soil is an excellent option as it doesn’t settle at a lower level. Choosing the right lawn seed mix for your situation is important to get the finished result you want. It is uncommon to get a lawn seed that is one single type of seed other than Kikuyu for very sandy situations or perhaps a Chewings Fescue for an ultrafine lawn. Most seed blends have different combinations to give the finished attributes that you want in the lawn. Lawns where there are kids or dogs running around or vehicles driving on the lawn have a coarser blade of grass (such as brown top) which stands up to the wear and tear. If you have shady spots, a hot and dry situation, a desire for a super fine, trophy lawn or just a regular lawn, choose a mix that is suited for that purpose. These blends will generally grow strongly in the warmer months and very little over the cold months. If you are in a situation where the lawn gets hard wear and tear all year round and has the potential to turn into a mud pit in winter, look for an all-season blend that grows during the cold months as well. It does mean you have to keep mowing your lawn in winter, but any damage has a chance to be repaired and the lawn regrows at any time of year. This is the blend they use on sports fields. Once your lawn seed has germinated, ensure that you oversow to fill in any patchy areas and ensure a thick, even lawn. Watering your lawn Lawns can use up a lot of resources in terms of water, but there are a few things to keep in mind. Most people over irrigate their lawns which can cause plants in surrounding gardens to die from overwatering – especially on heavy or clay-based soil. Reduce your watering to a longer time and further apart rather than a light water every other day. The finer the blade of grass the more water it requires, so if you want to reduce your water use over summer, oversow with a more drought resistant, coarser blade of grass and leave it cut higher during the summer months. If your lawn is on an automatic watering system, regularly check if the soil needs watering. If the soil is damp, it's fine, it doesn't need more water. An automatic system can’t tell if it has rained, and if water is not needed. That’s up to you! Mowing your lawn The lower you cut your lawn, the higher the risk of damage or death over summer with high temperatures and minimal rain and the higher the risk of weed invasion. If you mow your lawn higher, it is more resilient to heat stress and there is more competition to keep weeds at bay. Maintain the blades on your mower and keep them sharp to ensure a clean cut of the grass. Feeding your lawn Be aware that a new lawn is very soft and easily burnt by fertiliser or weed spray so you need to use a fertiliser specifically for new lawns that will be slow release or use a gentle option such as liquid seaweed for the first six months. What type of lawn fertiliser should I use? The three main options are slow release, granular and liquid. All have pros and cons. Slow release options are expensive, however a little goes a long way and lasts a few months. As it releases slowly the grass is fed consistently over a long time and it is not wasted. Follow the application instructions to apply the correct amount to the correct area size. Granular options are inexpensive but they can burn if they are applied too heavily. They also release on contact with water (this is why you need to water them in) which gives them a big feed at once but also has a high chance of leaching away and therefore be wasted. Liquid feed is easily applied and taken up quickly – an instant boost – but it is also used up quickly, so it must be applied regularly over the growing season. It commonly has a weedkiller included in the formulation to kill off weeds and the fertiliser then encourages the grass to grow and fill the space.

Autumn is often referred to as ‘nature’s time for planting’ when temperatures are still warm and there is more moisture in the soil. This makes it an excellent time to do some planting, with plants having the opportunity to get roots established before winter dormancy sets in. If your summer flowers have all finished, consider planting autumn flowering plants like echinacea and chrysanthemums that will perform as the summer flowers finish year after year. Start planting your annuals such as violas, pansies, primula and poppies to get established to carry you through the winter months. It's bulb planting time for spring flowering bulbs like daffodils, crocus, freesia, ranunculus and many more! Check to see if your bulbs need a winter chill to initiate flowering. An easy way to help them along is to store them in the fridge for a few weeks before planting, especially if temperatures are still warm. It is also bulb or tuber feeding time for our summer flowering bulbs/ tubers like dahlias that are beginning to finish their show. As they finish and start to die down, they take up food and store it in their tuber for next year's food source, so it is a good investment to get some bulb fertiliser applied now! Keep dead heading your flowering plants to help keep your flowers coming! You still have potentially a good month or two more of flowers to enjoy – depending on the weather. As perennials die down, cut back the dead foliage to tidy them up. Plants like delphiniums and peonies, you cut to ground level. Plants like salvias and penstemons should have some of their stems and foliage left to protect them from the cold. Put any diseased foliage in the rubbish bin. Give them a good weed to tidy up around them and apply a light mulch to protect them. Any vigorous clump forming perennials can be carefully dug up / lifted and divided to give you more plants and to maintain the health and vigour of the plant. Examples include agapanthus, delphinium, hosta and daylilies. You can wait until they have gone dormant or until there is some more moisture in the soil. Keep them well watered after dividing if they are not dormant. If you are keen on trying seed collecting, now is the time to do it. Don’t cut the flowerheads off when they are finished and let them form a seed head. You need to wait until the seeds have ripened – usually they turn from green to brown, black or red – before cutting the head off and popping them in a paper bag to fully dry out. Check every few days as they can be dispersed quite quickly after they ripen. Once they are fully dry, you’ll find you can shake the seeds out of the seed head, to collect in the paper bag. Remove the remains of the seed head to avoid issues with mould, pests or diseases. Store somewhere in a cool dry place and pop a desiccant packet (silica beads) in with them to keep them dry. If you are a sweet pea fan, get your seeds planted now so they can establish and grow over the colder months. You will have stronger plants that flower earlier if you get them planted now. At the end of autumn, if you have heavy soil or the forecast is for a wet winter, you can lift Dahlia tubers, to protect them from rotting. Wait until they have died right back, or a frost has knocked the leaves back. Carefully lift them and you can divide large tubers if you want more plants at this point. Just ensure you keep part of the crown with each division. Rinse the tubers off to clean them, let them dry and store in a cool, dry position until spring. Have a good clean up, removing any plant material, including fallen leaves, if they are or were infected with pests or diseases. This is the best way to help prevent issues the following year. As deciduous shrubs lose their leaves, give them a spray with a copper fungicide to help seal the wounds left by the leaf drop. Lastly, give your flower beds some love and spread a layer of fresh compost over the soil to add some nutrients after a busy season of flowering. It will help keep weeds down and improve your soil, which is always a good thing! Written for Gubba by Kelly Jean Reyland from Garden Advice NZ (www.gardenadvice.co.nz)
IN THE EDIBLE GARDEN In March you can plant the following in most areas of the country… beetroot, blueberry, bok choi, broad bean, broccoli, brussels sprouts, cabbage, cauliflower, carrot, celery, coriander, feijoa, kale, leeks, lemon, lettuce, lime, mandarin, mesclun, onion, orange, parsley, radish, rocket, silverbeet, spinach, spring onion. This lovely late-summer, early autumn period is a great time for sowing winter veg crops, as the temperatures are cooling but the soil is still warm enough for quick germination. As the season begins to turn and we look towards our winter veg, keep crop rotation in mind. Try not to plant veg from the same family in the same spot each year. Each growing season you should plant each 'family' of vegetables in a different position in the garden; read more on crop rotation here. HARVESTING Regularly harvest the last of your berries, tomatoes, beans, zucchini and cucumbers. Picking fruit and veg each day encourages late fruiting & growth (and also helps to keep pests at bay). Potatoes are ready for harvest when the tops have died back. Your pumpkins may be ready this month too. Kumara is ready to dig up once the leaves start to yellow. Dig up 1 or 2 to start with and check for things like size and firmness. Cut one in half and watch how quickly the cut sides dry - if they dry fast, the kumara is ready for harvest & storage. Dig up onions when the tops have gone brown. If the weather is good, leave them out on top of the garden bed to dry out for a few days - this helps them store better. IN THE FLOWER GARDEN Pull up your summer annuals once they have finished flowering (sunflowers, cosmos, marigold etc.) Plant winter flower seedlings such as snapdragon, alyssum, cosmos, pansy, poppies, viola, primula, polyanthus, cornflower, calendula, cineraria, lobelia, sweet peas, marigolds, etc. Deadhead / pick zinnias, roses, dahlias, echinacea, gladiolus, lilies, scabious, sweet peas. Your favourite spring flowering bulbs are in garden centres now! Getting some early bloomers in now means you’ll be able to enjoy early spring colour: Plant daffodil bulbs any time from late February to the end of May. Pick a cool spot for your hyacinth bulbs and plant throughout March and April. Other bulbs to plant now include crocus, bluebells, tulips, snowdrops and freesias. If you particularly like one type of flower, stagger your planting of that one variety. By planting a number every two weeks you’ll find you can extend your blooms (and picking) by a month to six weeks. Read more on that here. Most spring-flowering bulbs need consistent cool temperatures over winter (below 10°C during the day) in order to produce a flower bud. If you live in a warmer area you’ll likely need to pre-chill your bulbs before getting them in the ground; read more on pre-chilling here. Use a bulb planter (like this one from Sneeboer) for the most efficient planting! TASKS THIS MONTH... ☑ Seed saving: Save seeds from tomatoes, cucumbers, melons, beans, cucumbers, pumpkins and courgettes. Dry & store in labelled envelopes so they’re ready for spring-time sowing. We also have gorgeous Seed Storage Tins to help you keep things organised. ☑ Preparing your garden beds: It’s important to revitalise your soil after a busy growing season. You can do this by digging in some organic matter (compost, manure, seaweed, etc.) or by sowing some cover crops. Cover crops (like this clover blend) add nutrients back into the soil, and the nitrogen improves soil structure. You can read more about the benefits of cover cropping & how to do it here. ☑ Make the most of the warmer temperatures and abundant organic matter at the moment by composting! Fresh compost is the BEST way to improve your soil, and in turn your garden. If you don’t already have a compost bin, check out our range here. ☑ Divide your perennial herbs: thyme, chives, rosemary, sage.
