Sorrel
Rumex acetosa
Polygonaceae — the same plant family as rhubarb and buckwheat. Relatives share pests and diseases, which is why rotation plans group by family.
Sorrel (Rumex acetosa) is a perennial herb for USDA zones 3–7. It wants full sun and pH 5.5–6.8 soil, with about 1 in of water weekly. Watch for slugs and rust. Below: its full sourced profile from 5 extension sources, plus a planting calendar timed to your frost dates.
Typical dates for zone 6b — set your zone or ZIP for yours. This calendar assumes the crop is started indoors. Timing is a guide from the crop's sourced growth stages; confirm with your local frost dates and extension before you sow.
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 and the temperature that would kill it. 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.

Edible parts per source: leaf.
Compiled from the extensions cited below. Which ones actually show up depends on your region — your extension's local list is the last word.
Different parts differ — the edible part is the leaf; the notes below flag other parts or preparations.

We compile bare facts from these university-extension and horticultural sources, never copied prose. 13 of the 19 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.
