Salsa garden

Tomato, pepper, tomatillo, onion and cilantro, grown together because they go into the same bowl of salsa.

Why these are grouped

Chosen for the kitchen. None of these plants is known to help another. They go in the same bowl.

Plan this plant team ›

Space it needs

At least 3 m²32 ft². If your bed is smaller, the planner grays this plant team out, says why, and offers the nearest adaptation that fits. It never swaps in something else without telling you.

If your bed is smaller: Salsa garden (patio) (1 m²11 ft²).

Between seasons

Nothing is left living in the bed over winter; the whole planting is re-established.

What is in it

What it costs the ground

Rotation history belongs to the ground itself, so this is what the planner records about this patch after the plant team comes out.

Rules that decide where it fits

Any vegetables planted together help each other

Refuted

The planner won’t plan around this claim. What is known instead is below.

What is known: Some plant teams rest on a real way one plant acts on another. A kitchen bundle says only that you'll want these things in the same bowl. Both are good ways to plant. Only the first has plants working on each other.

Evidence: settled without a trial (definition).

For rotation, a plant team's crop families count across its whole bed

Promising

If you skip this, you lose real yield. The planner warns you.

How it works: Soilborne inoculum and overwintering pest stages disperse across the bed. A plant team dominated by one family forecloses that ground for that family's rotation interval.

Evidence: checked against 2 sources in the research-based literature.

Remedy

Rotate the whole bed the plant team occupied, including rows that family never grew in.

Some plants can't fruit from their own pollen, so they need a second plant of a different variety nearby.

Well established

If you skip this, you lose real yield. The planner warns you.

How it works: Many fruit trees carry self-incompatibility alleles at a single locus. When a pollen grain shares an allele with the pistil it lands on, the pistil rejects it and no seed sets. A plant's own pollen always shares its alleles, so it cannot fertilize itself. Neither can a second tree of the identical variety, which is genetically the same. Fertilization needs pollen from a genetically distinct plant.

Evidence: checked against 2 sources in the research-based literature.

Chestnut, Chinese: All are self-sterile. Two or more varieties or seedling trees are necessary to ensure adequate cross-pollination.

Pollen-Pistil Interaction in Response to Pollination Variants in Subtropical Japanese Plum (Prunus salicina Lindl.) Varieties
Japanese plum exhibits gametophytic self-incompatibility (GSI), a prezygotic reproductive barrier where genetically related pollen is rejected by the pistil ... governed by a polymorphic locus (S) ... Self-incompatibility occurs when the same S-allele is expressed in the haploid pollen grain and the diploid pistil.
Remedy

Plant at least two, and where the species needs a second cultivar make them different varieties. Two of the same will not pollinate each other.

Succession sowing at intervals of about two weeks extends harvest for short-DTM crops.

Promising

If you skip this, it still grows, just less well. The planner suggests it.

How it works: Sowing the same crop in batches about two weeks apart staggers when each batch matures, so the harvest arrives as a continual succession, with no single glut. It pays off only for short-DTM crops, whose quick turnaround lets several sowings ripen within a single season.

Evidence: checked against 1 source in the research-based literature.

Onion cultivar group must match site latitude.

Well established

If you skip this, the planting fails. The planner won’t allow it.

How it works: Bulbing fires when daylength crosses a cultivar's critical threshold (short ~10-12h, intermediate ~12-14h, long ~14-16h). A short-day cultivar grown too far from the equator crosses its low threshold early and bulbs prematurely on small plants, so bulbs stay small. A long-day cultivar grown too close to it never reaches its high threshold and fails to bulb. Changeover is around the 35th-38th parallel, north or south.

Evidence: checked against 2 sources in the research-based literature.

Bulb Onions NC State Extension
… onions will not form bulbs until daylength reaches the cultivar's critical threshold. Short-day onions bulb at approximately 10-12 hours of daylength ... Intermediate-day onions bulb at approximately 12-14 hours ... Long-day onions bulb at 14-16 hours of daylength.

Growing Onions in Central Illinois Univ. of Illinois Extension (The Humble Gardener)
Long day varieties are for northern growing areas (above the 35th latitude); short-day varieties are for southern. If short-day varieties are grown in our zone, they won't do well. They will not form bulbs of any decent size. And since the long day onions need more daylight, they will not do well
Remedy

Choose long-day onions far from the equator and short-day near it; the planner picks the group from your plot's latitude.
