A potager is a dinner party you can eat for six months
A potager garden is a traditional French kitchen garden that blends edible crops, vegetables, fruit and herbs, with decorative flowers. The word comes from potage, meaning soup. It is, literally, the garden for the soup pot. A vegetable patch feeds you. A potager feeds you and looks good doing it.
Which makes planning one exactly like preparing for a dinner party. The guest list and the meal, both at once. Who you want at the table, who can be trusted to sit next to who, who needs the early invite, who’ll turn up late, and who announces at the last minute that they don’t do full sun.
Real gardeners write the list in winter. Everyone else panics in spring.
Why the seating plan matters
Companion planting is the art of putting the right plants next to each other so they help instead of fight. It’s not folklore. It’s mostly about light, root depth, pests and pollinators.
Some pairings deter bugs. Some pull in beneficial insects. Some shade the soil for shallow-rooted neighbours. Some are just being polite.
Done well, you grow more food in less space with fewer problems. Done badly, you spend three months wondering why nothing fruited.
If you want the whole seating plan in one place, Companion Planting in New Zealand by Brenda Little is the book we reach for. It is small, cheap and settles arguments.
Who to seat together
Tomatoes, basil and marigolds. The classic. Basil masks the smell of tomato leaves from whitefly and aphids. Marigolds suppress root knot nematodes and pull in hoverflies. You can also harvest dinner in three steps.
Carrots and onions or leeks. Carrot fly hates the smell of allium. Onion fly hates the smell of carrot. Plant them together and both pests get confused and leave. Sow in alternating rows.
Beans, corn and squash. The Three Sisters. Corn is the climbing frame, beans fix nitrogen for everyone, squash shades the soil and smothers weeds. Works brilliantly here if you sow in October once the soil is properly warm.
Brassicas with dill, sage or rosemary. Cabbage white butterfly is the bane of every brassica grower. Strongly scented herbs nearby confuse them. Add nasturtiums as a sacrificial trap crop and you have a proper defence.
Lettuce under the tall crops. Lettuce bolts in summer heat. Plant it on the shady side of beans, corn or staked tomatoes and you will add weeks to the season. The big crops drink first, but lettuce only needs the leftovers.
Who can’t be seated together
- Onions and beans. Alliums stunt legumes.
- Fennel and almost everyone. It is antisocial, give it its own corner.
- Brassicas and strawberries. Same nutrients, constant argument.
- Tomatoes and brassicas. Both heavy feeders, both pest magnets, keep them apart.
The guests who do the actual work
No bees, no fruit. Half a potager should be flowers, and this is where it stops being a vegetable patch. Borage, calendula, alyssum, phacelia, lavender, sunflowers, cosmos. Slot them between the veg, not in a separate pretty zone.
Borage in particular earns its keep. Bees love it, it self-seeds politely, and the cucumber-flavoured flowers go in salads.
For the design side of it, the beds, the structure, the bit that makes a potager a potager, The Natural Garden by Xanthe White is worth the shelf space.
Writing the list
Get a piece of paper. Sketch your beds to scale. Do not overthink the drawing.
- List what you actually eat. Skip the kohlrabi if nobody in the house likes kohlrabi.
- Mark sun and shade. Tall crops go south so they do not shade the smaller ones.
- Group the families. Nightshades together, brassicas together, alliums together. That makes crop rotation next year possible without a spreadsheet.
- Slot the companion pairs in. Tomato, basil, marigold. Carrot and onion. Lettuce under the beans.
- Leave gaps for succession sowing. The lettuce you eat in November needs someone coming up behind it for January.
- Add the flowers last, threaded through. This is the bit that makes it a potager and not a row of crops.
If you are starting the edible side from scratch, Organic Vegetable Gardening by Xanthe White covers the growing in more detail than we can fit here.
Send the invitations early
The best varieties sell out in August. Order now and everything is ready when the soil warms.
Write your sowing dates straight onto the seed packets when they arrive. You will thank yourself on the first warm morning, when everything else is chaos.
The point
The garden that thrives in summer is the one you sketched in August. Planning is not precious. It is the single biggest favour you can do for September you.
Welcome to the dirt cult. We plan in pencil and harvest in armfuls.
