Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge, followed by first true leaves. Plant is very delicate and small.

Keep soil warm (70-75°F) and consistently moist. Provide bright light (grow lights if indoors). Thin seedlings to strongest plant if direct sown.

2

Vegetative Growth

3-5 weeks

Plant develops multiple sets of true leaves and bushy branching structure. Stems are green with purple tinges. No flowers yet.

Pinch off top 1-2 inches regularly to encourage bushier growth. Reduce pinching 3-4 weeks before harvest to allow branching.

3

Pre-Flowering

2-3 weeks

Plant reaches 8-12 inches tall with full canopy. Flower buds begin to form at stem tips.

Continue moderate watering and full sun exposure. Pinching off early flower buds redirects energy to leaf production for longer harvest.

4

Flowering

4-8 weeks (continuous if deadheaded)

Purple-pink flowers bloom in spiky terminal clusters. Plant energy shifts toward seed production. Leaves become smaller and less flavorful.

Deadhead spent flowers to extend vegetative growth and leaf production. If allowing to flower for ornamental purposes, maintain regular watering.

5

Seed Production & Decline

2-4 weeks (or ongoing in containers indoors)

Flowers mature into seed pods. Leaves diminish in quantity and flavor. Plant gradually senesces.

Allow selected flowers to dry on plant if saving seeds. Cut back plant by one-third to encourage new growth, or end season.

Harvest Tips

Begin harvesting leaves once plant has 6-8 true leaves, typically 30-40 days after planting. Pinch off top 1-2 inches regularly for continuous harvest. For best flavor, harvest in the morning after dew dries. Remove flower buds to extend leaf production. Harvest entire plant 2-3 weeks before expected frost by cutting back to 1/3 of its height; it will regrow if season permits. Harvest regularly to prevent woodiness.
