Growth Stages

1

Seedling

10-14 days

Tiny plants with cotyledons and first true leaves developing. Very delicate and light-sensitive.

Provide bright light (grow lights 2-3 inches above seedlings), maintain 70-75°F soil temperature, keep soil moist but not waterlogged, and gently fan seedlings to strengthen stems.

2

Vegetative Growth

4-6 weeks

Plant develops 6-8 true leaves and becomes stockier. Stem thickens and root system expands rapidly.

Pot up into larger containers as needed, maintain consistent moisture, provide full light, and begin gentle outdoor hardening off 7-10 days before transplanting.

3

Flowering

3-4 weeks

Yellow flowers appear in clusters (typically 5-8 flowers per inflorescence). Plant reaches mature height and branching structure.

Ensure adequate light, maintain consistent watering, support plant with stakes or cages, remove lower leaves as plant grows, and maintain 70-80°F temperatures for optimal pollination.

4

Fruit Development

4-5 weeks

Flowers transition to small green fruits that gradually enlarge. Golden coloring begins to develop as fruits mature.

Prune selectively (remove excess suckers on determinate varieties only if crowding), maintain steady watering schedule, fertilize every 2-3 weeks with balanced formula, and monitor for pests and diseases.

5

Harvest

3-4 weeks

Fruits reach full golden-yellow color with slight give when gently squeezed. Flavor is sweet and rich at full ripeness.

Harvest when fully colored but before over-ripening; can pick at light-yellow stage and ripen indoors; typically produces 30-50 fruits per plant; harvest regularly to encourage continued production.
