Tomatillo

Physalis philadelphica

Solanaceae — the same plant family as tomato, pepper, potato, eggplant and 3 more here. Relatives share pests and diseases, which is why rotation plans group by family.

Tomatillo (Physalis philadelphica) is an annual vegetable. It wants full sun and pH 6–7 soil, with about 1–2 in of water weekly. It matures in about 100–120 days from sowing, or 60–100 days from setting out a transplant. Watch for aphids and early blight. Below: its full sourced profile from 5 extension sources, plus a planting calendar timed to your frost dates.

What we will not put a number on

We do not give a feeding rate for this crop, and that is deliberate rather than a gap. The figures published by extension services are pounds of nitrogen per acre for a production field — they do not convert safely to a raised bed or a pot without knowing your soil test and your fertilizer's analysis, and guessing errs toward burning roots. It is also why every chart you find online disagrees with the next one.

We give watering as a depth per week rather than gallons per plant, because that is how it is actually measured and how the published figures are written. A gallons-per-plant number depends on your spacing, your soil and whether the plant is in a pot — so it would look more precise than it is.

No published figure for the temperature frost starts to hurt it, the temperature that would kill it and a warm-night limit. We looked — where a number is missing here it is missing from the research, not skipped. The crop’s frost and heat tolerance above still applies.

Planted again for autumn

Set plants out by
late Aug typical · zone 6b

60 days to maturity from setting a plant out — that is what our sources measure for this crop, so this is a date for planting out and not a sowing date, counted back from the first frost above. Not published for anywhere in particular: it is your own frost date and this crop's own figure, which is why it works wherever you are. A days-to-maturity figure is a catalog number for a good season rather than a promise, and a cold month moves it.

We compile bare facts from these university-extension and horticultural sources, never copied prose. 16 of the 20 values on this page carry a citation. The rest are marked est; hover one and it says why — either nobody publishes a figure we could point at, or a person set it and attached no source. Figures vary with climate and seed source; confirm with your local extension before you buy.
