Growth Stages

1

Seedling

3-4 weeks

Tiny plants with first true leaves appear 1-2 weeks after germination. Growth is slow initially.

Maintain 70-75°F soil temperature. Use grow lights if needed. Keep soil moist but not waterlogged. Thin to strongest seedlings.

2

Vegetative

4-6 weeks

Plant develops multiple stems and leaves. Compact, bushy form typical of Eight Ball variety. No flowers yet.

Harden off seedlings before transplanting. Provide consistent warmth (65-80°F). Fertilize bi-weekly with balanced fertilizer. Stake or support if needed.

3

Flowering

3-4 weeks

Purple or lavender flowers appear at leaf axils. Flowers are small and delicate. Plant continues growing new stems.

Ensure pollination by hand if needed or provide bee access. Continue regular watering. Switch to higher phosphorus fertilizer to encourage fruiting. Remove any damaged flowers.

4

Fruiting

3-4 weeks

Young fruits form at flower sites, initially green then gradually darkening to glossy deep purple. Fruits become round and billiard ball-shaped.

Support fruit-laden branches with stakes or cages. Maintain consistent watering to prevent blossom end rot. Reduce nitrogen fertilizer. Thin fruit if overcrowded (remove smallest).

5

Harvest

Ongoing, 6-10 weeks total harvest period

Fruits reach 2-3 inches in diameter, deep purple color, glossy finish, and firm texture. Ready for harvest.

Harvest when fruits reach full size but before skin loses shine. Use pruners to cut stem. Plant continues producing until frost.

Harvest Tips

Harvest when fruits are 2-3 inches in diameter with deep purple, glossy skin. Fruits should feel firm and slightly yield to gentle pressure. Cut with pruners rather than pulling to avoid damaging stems. Harvest regularly to encourage continued production. Pick before fully mature if skin begins to dull, as this indicates overripeness. Morning harvest after dew dries is ideal.
