Actual harvests vary by variety, weather, soil, fertility, pests, disease, irrigation, spacing, and harvest stage. This is a planning estimate—not a guarantee.

Adjust this estimate for your household

Plant more if you preserve heavily or eat the crop often. Plant less for occasional use. Succession planting can provide steadier harvests than planting the full amount at once.
