Growth Stages

1

Seedling

3-4 weeks

Tiny cotyledons emerge; true leaves appear within 1-2 weeks. Seedlings are delicate with thin stems.

Keep soil consistently moist. Provide 14-16 hours of grow light 2-3 inches above seedlings. Maintain 70-75°F for optimal germination.

2

Vegetative

4-6 weeks

Plant develops sturdy stems and oval, lobed leaves. Compact branching habit begins to show; plant remains bushy and low-growing.

Transplant to larger containers when 2-3 true leaves appear. Harden off gradually before moving outdoors. Begin weekly feeding with balanced fertilizer once established.

3

Flowering

3-4 weeks

Purple flowers with yellow centers emerge at leaf axils. Multiple buds develop along stems simultaneously, creating dense flowering clusters.

Maintain consistent soil moisture and warmth (65-75°F nights minimum). Switch to lower-nitrogen, phosphorus-rich fertilizer. Hand-pollinate flowers or gently shake stems to ensure fruit set.

4

Fruiting

3-4 weeks to first harvest

Small, glossy dark purple fruits develop from flowers. Fruits elongate to 4-6 inches with smooth skin; can set 15-25 fruits per plant.

Support branches with light stakes or cages if fruits become heavy. Maintain consistent watering to prevent fruit cracking. Continue balanced feeding every 2-3 weeks.

5

Harvest

6-12 weeks (ongoing through season)

Fruits reach full size with dark purple, glossy skin. Flesh remains creamy and tender; seeds are small and underdeveloped.

Harvest regularly (every 2-3 days) to encourage continued production. Use pruning shears to cut fruits with 1-inch stem attached. Plant continues producing until frost.
