Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with delicate cotyledons and first true leaves emerging

Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to proper spacing once they develop true leaves.

2

Vegetative

3-4 weeks

Young plants developing bushy foliage with small, oval-shaped leaves

Water moderately and pinch back growing tips to encourage bushier growth. Fertilize every 2-3 weeks with balanced fertilizer if growing in containers.

3

Establishment

4-6 weeks

Mature plant with full foliage, becoming more compact and dense

Continue regular watering and harvesting to promote bushiness. Plant can now tolerate slightly drier conditions. Mulch to conserve moisture.

4

Flowering

4-8 weeks

Small, pale pink or white flowers appear in clusters at stem tips

Pinch off flowers for culinary use, or allow some to bloom for ornamental value and pollinator attraction. Flowering slightly reduces leaf flavor intensity.

5

Harvest

Ongoing throughout growing season

Plant is full and ready for regular leaf harvesting throughout the season

Harvest regularly to maintain shape and promote new leaf production. Cut stems just above leaf nodes. Remove flowers if prioritizing leaf flavor.

Harvest Tips

Begin harvesting leaves when the plant has at least 6 inches of growth. Pinch or cut stems just above a leaf node to encourage bushiness. For best flavor, harvest in the morning after dew dries. Can be harvested continuously throughout the growing season. Dry leaves by hanging in bundles or using a dehydrator for storage.
