Growth Stages

1

Germination & Seedling

1-2 weeks

Tiny seeds germinate quickly in warm, moist soil. Seedlings emerge with cotyledons followed by true leaves within 1-2 weeks.

Keep soil warm (70-80°F) and consistently moist. Provide bright, indirect light. Thin seedlings to prevent overcrowding.

2

Vegetative Growth

2-3 weeks

Plant develops multiple stems and tender leaves. Foliage becomes lush and bushy with rapid height and lateral branching.

Water regularly and maintain consistent moisture. Fertilize weekly with balanced or nitrogen-rich fertilizer. Pinch off tops to encourage bushier growth.

3

Leaf Development & Expansion

1-2 weeks

Leaves grow larger and more abundant along stems. Plant reaches harvestable size with tender, succulent foliage.

Continue regular watering and fertilization. Ensure good air circulation to prevent fungal issues. Begin light harvesting of outer leaves.

4

Mature & Productive

4-8 weeks (ongoing in warm climates)

Plant is fully established with dense foliage. Continues producing tender leaves and stems throughout the growing season.

Harvest regularly to encourage continued branching and leaf production. Maintain consistent moisture and monthly fertilization. Remove any flowering stems promptly.

5

Decline (Bolting)

Variable, seasonal

Plant may begin flowering and produce less tender foliage as temperatures rise or day length increases.

Pinch off flower buds to redirect energy to leaf production. In very hot seasons, provide afternoon shade or consider succession planting.

Harvest Tips

Begin harvesting 30-45 days after planting when plants are 6-8 inches tall. Pinch off tender tips and upper 2-3 inches of stems regularly to encourage bushiness and prolong productivity.
