Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with fine, thread-like cotyledons and first true leaves appearing within 2-3 weeks

Maintain consistent light and moderate moisture. Provide bright indirect light or grow lights. Avoid overwatering seedlings.

2

Vegetative Growth

4-6 weeks

Plants develop dense, bushy foliage with characteristic narrow, silver-green leaves. Compact growth habit becomes apparent.

Pinch back growing tips to encourage branching and fuller plants. Reduce watering frequency. Apply minimal fertilizer—lavender prefers lean soil.

3

Flowering

6-10 weeks (can bloom in waves)

Dense purple flower spikes emerge above foliage, with individual tubular florets opening progressively along the spike

Deadhead spent flowers to encourage additional bloom cycles. Provide full sun exposure. Reduce irrigation to concentrate essential oils.

4

Establishment/Hardening

Throughout growing season

Plant develops stronger root system and woody base; foliage becomes more aromatic and silvery

Minimal supplemental watering. Light pruning after flowering to maintain shape. No fertilizer needed.

5

Dormancy

3-4 months (fall/winter)

Winter rest period; foliage remains but growth slows significantly; some varieties may retain dried flower heads

No watering during dormancy in wet climates. Ensure excellent drainage. Prune dead wood in early spring. Mulch lightly with gravel in zone 5.

Harvest Tips

Harvest flower spikes in early morning after dew dries but before peak heat, when lowest florets are fully open and upper florets are still closed. Cut stems 6-10 inches long just above the foliage. For fresh use, cut anytime; for drying, harvest at peak bloom. Deadhead regularly to extend blooming season. Cut back plant by one-third after main flowering to rejuvenate growth.
