Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with cotyledons emerge, developing first true leaves within 1-2 weeks

Provide 14-16 hours of bright light daily under grow lights. Keep soil consistently moist but not waterlogged. Maintain 70-75°F temperature.

2

Vegetative Growth

4-6 weeks

Plant develops sturdy stems and numerous leaves. Plant grows 6-12 inches tall before being hardened off for transplanting

Gradually increase light intensity and air circulation. Thin seedlings or pot up individually when 2-3 true leaves appear. Begin fertilizing weekly with diluted balanced fertilizer.

3

Establishment & Flowering

3-4 weeks

After transplanting to garden, plant establishes roots (1-2 weeks), then begins flowering with small yellow flowers appearing in clusters

Install sturdy stakes or cages immediately. Pinch off lower leaves as plant grows. Apply consistent deep watering. Mulch around base to retain moisture and regulate temperature.

4

Fruit Development & Ripening

4-6 weeks

Small green fruits develop from flowers and gradually mature to deep purple-black color. Fruits are ready 20-30 days after flowering

Maintain consistent watering to prevent cracking. Prune excessive foliage to improve air circulation and sun exposure. Remove some lateral branches if plant becomes too dense. Monitor for pests.

5

Peak Harvest

6-10 weeks

Plant produces continuous crops of dark purple-black fruits throughout season until frost. Fruits reach maximum color and flavor when fully ripe

Harvest ripe fruits regularly to encourage continued production. Continue watering and monitoring for late-season pests. In zones 3-4, extend season with row covers or harvest green fruits before frost.
