Growth Stages

1

Seedling

4-8 weeks

Tiny seedlings with fine needle-like cotyledons and primary leaves beginning to emerge

Keep soil moist but not waterlogged; provide bright indirect light; maintain consistent warmth (65-75°F). Handle carefully as seedlings are delicate.

2

Vegetative Growth

3-6 months

Young plant developing bushy form with narrow, linear, aromatic leaves; no flowers yet

Maintain moderate moisture during establishment; gradually acclimate to full sun; avoid heavy fertilization. Prune lightly to encourage branching if needed.

3

Pre-flowering

2-4 weeks

Mature plant developing terminal flower buds at branch tips; dense foliage well-established

Reduce watering slightly to encourage flowering; maintain full sun exposure; avoid over-fertilizing. Do not prune at this stage.

4

Flowering

6-12 weeks

Plant covered with clusters of small white to pale pink flowers; highly ornamental

Maintain consistent watering during bloom; allow flowers to complete cycle. Do not deadhead unless harvesting for cut flowers.

5

Post-flowering

8-12 weeks

Flowers fade to brown seed capsules; plant focuses on seed production and growth

Reduce supplemental watering; maintain full sun. Light pruning can be done after flowering to maintain shape, but avoid removing too much growth.
