📷 Wikimedia CommonsStarting Ichiban: indoors or direct sow?
🏠 Start indoors 10 weeks before your last spring frost, then move the seedlings outside.
Transplant seedlings outdoors only after all danger of frost has passed and soil temperatures have warmed sufficiently.
Soil, care & harvest
Prepare rich, loose soil with a pH between 6.0 and 6.8 before sowing. As a warm-season crop, start seeds indoors about 10 weeks before your last frost date. Sow seeds 1/4 inch deep; they typically germinate within 10 to 14 days once the soil is consistently warm.
Space plants 18 to 24 inches apart in full sun, ensuring consistent moisture for healthy growth. Apply a thick layer of mulch around the base to retain water and suppress weeds. Feed regularly with a balanced fertilizer to support heavy fruit production throughout the growing season.
Watch for flea beetles, Colorado potato beetle, aphids, Verticillium wilt, bacterial wilt, and early blight. Prevent issues by rotating crops, using row covers, and ensuring good air circulation. Harvest fruits when they reach full size and deep color, usually 61 to 70 days after planting.
