Growth Stages

1

Seed Germination

7-10 days

Tiny seedlings with two small cotyledons emerge from soil; very delicate at this stage.

Keep soil warm (70-75°F), moist but not saturated. Provide bright indirect light. Use a heating mat if needed. Thin seedlings to 2-3 inches apart.

2

Seedling & Transplant

3-4 weeks

True leaves appear, plant develops root system. Seedlings reach 3-4 inches tall with 2-3 sets of true leaves.

Provide bright light (12-16 hours). Keep soil consistently moist. Harden off gradually before transplanting outdoors. Protect from wind and cold.

3

Vegetative Growth

4-6 weeks

Plant establishes bushy form with increasing ruffled foliage. Leaves become larger and more textured, plant reaches 8-12 inches tall.

Pinch off flower buds and top growing tips to encourage bushier, leafier growth. Water regularly. Feed with balanced liquid fertilizer every 2 weeks.

4

Flowering

Ongoing if not deadheaded

Small white or pale pink flowers appear in terminal spikes. Flowering signals plant is preparing to set seed.

Pinch off flowers immediately to redirect energy to leaf production and delay senescence. Flowering reduces leaf flavor intensity.

5

Harvest

Until frost or senescence

Plant is mature and producing abundant ruffled leaves ready for culinary use. Plant may begin to decline if flowers are not removed.

Harvest regularly to encourage continued growth. Pick from top down, removing no more than 1/3 of plant at a time. Use within a few hours for best flavor.

Harvest Tips

Begin harvesting when plant is 6-8 inches tall by pinching off the top 2-3 leaf sets. Harvest regularly and frequently—this encourages bushier growth and delays flowering. Pick leaves in the morning after dew dries for best flavor and aroma. Use leaves fresh immediately or refrigerate in a damp paper towel for up to one week. For longer storage, freeze in ice cube trays with water or olive oil, or dry by hanging or using a dehydrator at low temperature (95-115°F).

Fun Facts
