Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with 2-4 true leaves; slow initial growth

Keep soil lightly moist but not waterlogged. Provide bright light. Thin seedlings to prevent crowding.

2

Vegetative Growth

4-8 weeks

Plant develops bushy form with increasing small gray-green foliage

Reduce watering as plant establishes. Begin light pinching to encourage bushiness. No fertilizer needed on poor soil.

3

Pre-flowering

2-3 weeks

Plant becomes more compact and woody; leaf flavor intensifies

Continue light watering. Plant is drought-tolerant at this stage. Light pruning maintains shape.

4

Flowering

4-8 weeks (spring/early summer)

Delicate pink, purple, or white flower spikes appear along stem tips

Flowers are edible and attract pollinators. Harvest leaves before heavy flowering for best flavor, or allow flowering for ornamental interest.

5

Dormancy/Winter Rest

3-4 months

Growth slows significantly in cold regions; plant retains foliage but may look sparse

Minimal watering. No fertilizer. In zones 5-6, provide light mulch protection. Prune back dead wood in early spring.

Common Pests

  • Spray with neem oil or insecticidal soap; use yellow sticky traps

  • Increase humidity; spray with water or neem oil; ensure good air circulation

  • Manually remove or spray with horticultural oil in dormant season

  • Improve drainage immediately; reduce watering; repot in fresh, well-draining soil if in containers

Harvest Tips

Begin harvesting when plant is 6 inches tall, cutting leaf tips regularly to encourage bushiness. Best flavor is before flowering. Pinch off top 1/4 to 1/3 of stems. For drying, harvest in early morning after dew dries but before hot sun, ideally just before flowering. Hang dry in bundles in a warm, airy location for 1-2 weeks. Can be frozen fresh or dried for storage.
