Pest management: Corn cultural tips, pests, and diseases
When to plant: Direct seed May–June (possibly April and July). Plant every 2–3 weeks for successive harvest (or when the most recent seedlings have 3–4 leaves).
Harvest window: Sweet corn is ready for harvest about 17 to 24 days after the first silk strands appear, more quickly in hot weather, more slowly in cool weather.
Care overview: Corn is wind-pollinated, so planting in blocks of at least 3 to 4 short rows will be more successfully pollinated than one or two long rows.
