Any co-planted set of vegetables is a guild.
Evidence: settled without a trial - definition.
Salad Garden
A culinary bundle - grown together for the kitchen, with no interspecies claim made.
Space it needs
At least 3 m². A bed smaller than that does not get this guild quietly substituted for something else — the planner greys it out, says why, and offers the nearest adaptation that does fit.
Between seasons
Nothing is left living in the bed over winter; the whole planting is re-established.
What it claims
No interspecies mechanism is claimed. It is grouped for a reason, and that reason is written below rather than dressed up as biology.
The honest version
No interspecies mechanism — a co-harvest for the salad bowl. What it teaches is timing: the quick radish and cool-season lettuce come and go (both carry bolt risk, so succession fires) while the warm-season tomato and cucumber are still ripening. This bed is really two or three successions, not one planting.
What is in it
What it costs the ground
Rotation history attaches to the ground, not the bed, so this is what the planner remembers about this patch after the guild comes out.
- Nightshades: full load
- Cucurbits: full load
- Brassicas: partial load
- Alliums: partial load
Rules that gate it
A guild deposits family history across its whole footprint.
Mechanism: Soilborne inoculum and overwintering pest stages disperse across the bed. A guild dominated by one family forecloses that ground for that family's rotation interval.
Evidence: confirmed against 2 sources in the research-based literature.
the 2 sources
Same soilborne-persistence basis as other rules here (read 2026-07-11): NC State Extension (Verticillium microsclerotia 'can survive in the soil without a host for up to 10 years'; Septoria/early blight 'overwinter on infected tomato debris and solanaceous weed hosts') and UMN/Ohioline (squash bug overwinters 'as adults in sheltered places ... they fly to growing cucurbit plants'; squash vine borer 'overwinters in the soil as a pupa').
Those sources establish that inoculum and pest stages persist in the ground and are not confined to the exact spot a plant occupied; this rule applies that persistence across the whole guild footprint. The whole-footprint attribution is the corpus's rotation geometry (history attaches to ground, not to the individual plant — see the data model), not a claim from an external source.
remedy
Rotate the whole bed the guild occupied, not just the rows that family grew in.
Succession sowing at 2-3 week intervals extends harvest for short-DTM crops.
Mechanism: Staggered maturity.
Evidence: confirmed against 1 source in the research-based literature.
