Germination
7-14 daysTiny seedlings emerge with cotyledons (seed leaves) and first true leaves begin to appear.
Keep soil warm (70-75°F) and consistently moist. Provide bright light to prevent leggy seedlings. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
3-4 weeksPlant develops multiple stems and increasingly deep purple foliage. The distinctive dark burgundy color intensifies with sunlight exposure.
Pinch off growing tips regularly to encourage bushier growth and prevent early flowering. Feed with balanced fertilizer every 2-3 weeks. Remove any weak or spindly stems.
Pre-Flowering
2-3 weeksPlant reaches mature height with full bushy foliage. Flower buds begin to form at the top of stems.
Continue pinching back flower buds to extend the vegetative growth phase and encourage leaf production. This maintains tenderness and flavor. Water consistently and monitor for pests.
Flowering
2-4 weeks (continues through season if not pinched)Delicate pink or light purple flowers appear in terminal spikes. Flowering signals the plant is ready to set seed.
Harvest heavily before flowering to delay seed set and maintain leaf quality. If you want seeds, allow some flowers to remain. Flowers are edible and attractive in salads or as garnish.
Seed Production & Decline
Variable; 3-4 weeks to mature seedsFlowers develop into seed pods. Leaf quality and flavor deteriorate as energy is directed to seed production. Plant becomes woody and less productive.
If harvesting seeds, allow pods to dry on plant until brown and papery, then collect. For continued leaf harvest, remove flowering stems promptly. In cooler climates, plants begin declining as temperatures cool in fall.
Common Pests
-
Spray neem oil or insecticidal soap weekly; introduce yellow sticky traps; remove heavily infested leaves. Improve air circulation.
-
Spray with strong water stream to dislodge; use neem oil or insecticidal soap; encourage beneficial insects like ladybugs.
-

Harvest Tips
Begin harvesting when plant has 6-8 true leaves. Pinch off the top 0.5-1 inch of growing tips regularly to encourage bushier growth and continuous production. Harvest in the morning after dew dries for best flavor and aroma. Remove leaves from the top down, allowing lower stems to continue growing. Never remove more than one-third of the plant at once. For best flavor, harvest before flowers fully open. Continuous harvesting extends the plant's productive life and delays flowering.
