Hardiness: Very tender warm-season annual. Frost will injure top growth; needs warm weather to grow.
Planting: Transplant after all danger of frost is past and when the soil has warmed. Full sun requires direct light at least 6 hours/day; prefers 8 – 10 hours/day.
Days to maturity: 65 – 90 from transplant.
Spacing: 18”-36”in-rows x 48”-60” between row. Spacing depends on such factors as the growth habit of the plants and whether staked or caged.
Fertilizer needs: High requirement for nutrients, either from soil organic matter or fertilizers. Use starter fertilizer for transplants. Side-dress after first fruits appear. Additional fertilizer may be needed depending on plant growth, fruit load, and soil fertility. Do not add Epsom salts (magnesium sulfate) to the soil unless soil testing shows a magnesium deficiency. Refer to Fertilizing Vegetables for details.
Approximate yield: 15 – 45 lbs. per 10-ft row.
