Growth Stages

1

Seedling (6-8 weeks)

6-8 weeks

Small plants with 2-4 true leaves, 2-4 inches tall. Cotyledons visible initially, followed by true leaves with serrated edges.

Maintain 75-85°F temperature; provide 14-16 hours of grow light 2-3 inches above seedlings. Keep soil consistently moist. Thin to strongest seedlings if crowded.

2

Hardening Off & Transplant (2-3 weeks)

2-3 weeks

Seedlings reach 4-6 inches tall with sturdy stems and 6-8 true leaves. Ready for outdoor hardening when night temperatures consistently above 55°F.

Gradually expose to outdoor conditions over 7-10 days. Harden off in shade first, then partial sun. Transplant to garden after last frost when soil is warm (65°F+).

3

Vegetative Growth (4-6 weeks post-transplant)

4-6 weeks

Plant establishes in garden, producing bushy growth, new leaf sets, and strong branching. Height reaches 18-24 inches.

Water deeply 2-3 times weekly. Apply 2-3 inch mulch layer. Begin fertilizing every 2 weeks with balanced or slightly nitrogen-rich fertilizer. Support stems with stakes if needed.

4

Flowering & Fruiting (6-8 weeks)

6-8 weeks

Purple-violet flowers appear at branch tips, followed by small fruit set. Fruits develop from golf-ball to full mature size (6-8 inches long).

Maintain consistent watering; fluctuations cause blossom drop. Thin excessive fruit clusters, retaining 4-6 fruits per branch for larger sizes. Continue regular fertilizing; switch to lower nitrogen if excessive leaf growth.

5

Harvest & Mature Production (8+ weeks)

8+ weeks

Fruits reach full size with deep glossy purple color and tender skin. Plant continues producing new flowers and fruits if harvested regularly.

Harvest fruits when glossy and full-sized but before skin becomes dull (overripe). Use pruners to cut from plant. Continue watering, mulching, and fertilizing to sustain production through season. Remove any yellowing leaves.

Harvest Tips

Harvest when fruits are 6-8 inches long, fully colored (deep purple), and skin is glossy and firm to slight pressure. Fruits are best harvested before they become dull or wrinkled (sign of overripeness). Use pruning shears or knife to cut from plant, leaving 1-inch stem attached. Harvest every 2-3 days during peak production to encourage continued flowering. Best flavor occurs when skin is tender; older fruits develop tougher skin and more seeds. In cooler zones, harvest all fruit before first frost and store in cool location (50-55°F) for 1-2 weeks if still firm.
