Guilds & Companion Planting
How a handful of well-chosen plants can support a fruit tree — and each other — so the whole group nearly tends itself.
If the seven layers describe the structure of a food forest, guilds describe its relationships. A guild is a small community of plants gathered around a central element — usually a fruit tree — chosen so that each member does a job the others benefit from. Done well, a guild is largely self-supporting: it feeds itself, protects itself, and needs less from you.
The classic parts of a guild
Think of a young apple tree at the centre. Around it you might plant:
- A nitrogen fixer — clover, lupin, or a shrub like sea buckthorn — that pulls nitrogen from the air and shares it, feeding the tree for free.
- A dynamic accumulator — comfrey is the favourite — whose deep roots mine minerals from far below, then hand them back when you chop its leaves for mulch.
- Pollinator plants — flowering herbs that draw in bees and hoverflies to set fruit and eat pests.
- Pest-confusers — alliums like garlic and chives, whose scent muddles the insects looking for your tree.
- Ground cover — strawberries or creeping herbs that shade the soil, hold moisture, and crowd out weeds.
None of these are doing you a favour out of kindness — each simply thrives while, as a side effect, making its neighbours’ lives better. That is the quiet genius of a guild.
The oldest guild of all
The idea is ancient. The Indigenous Three Sisters — corn, beans, and squash — is a guild you can plant in a single season: corn gives the beans a trellis, the beans fix nitrogen for the corn, and broad squash leaves shade the soil as living mulch. Together they even make a more complete meal than any one of them alone.
Start with one
You don’t need to design a whole forest to begin. Plant one tree and its guild, watch how the pieces support each other for a season or two, and you will have learned more than any book can teach. From there, the forest grows one guild at a time. Here’s how to start small.
