Corn Seeds,
Chapalote

Plant Chapalote corn after the last spring frost, when soil temperatures remain above 60°F. This ancient variety prefers warm, dry conditions and matures best during long summer days. In cooler regions, sow indoors in biodegradable pots 2–3 weeks before transplanting outdoors. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

Sow seeds 1–2 inches deep in fertile, well-drained soil enriched with compost. Space plants 12 inches apart in rows 30–36 inches apart. For strong pollination, grow in blocks of at least four rows. Water evenly during germination and early growth. Avoid overwatering once plants are established, as Chapalote’s desert heritage favors slightly drier conditions.

Keep soil moist but not soggy during the vegetative stage. Once tasseling begins, ensure adequate moisture to support kernel fill. Fertilize with organic compost or fish emulsion midseason. Chapalote thrives in hot, sunny environments and tolerates low fertility better than most corn types. Harvest when husks are dry and kernels are hard. Ideal for nixtamalization, flour, or decorative use.

• Corn is wind pollinated and will easily cross with other varieties (including GMO corn!). You will need at least 1 mile of isolation to avoid cross pollination. You can also use staggered timing or caging techniques.
• Hand pick ears when fully dried on stalk. Seeds keep best if left on the ear; just remove at planting time.
• Sweet corn seeds will remain viable for 2 years; dent corn will last up to 5 years when properly stored.
