Growth Stages

1

Seedling/Establishment

3-4 weeks

Young plants with soft, gray-green foliage developing first true leaves; roots establishing in soil

Keep soil lightly moist, not wet. Provide bright light. Gradually acclimate to outdoor conditions if starting indoors.

2

Vegetative Growth

4-8 weeks

Plant develops fuller foliage mound with silvery-green leaves; no flowers yet; height reaches 12-18 inches

Water sparingly once established. Begin reducing watering frequency. Pinch stem tips early on to encourage bushy growth. Ensure excellent drainage.

3

Budding & Early Flowering

2-3 weeks

Flower buds form at stem tips; first purple flower spikes appear; plant reaches mature compact size

Maintain dry conditions. Deadhead spent flowers to encourage continued blooming. Reduce fertilizer; lavender prefers lean conditions.

4

Peak Flowering

6-8 weeks (mid-summer through early fall)

Abundant purple-violet flower spikes in full bloom; strong fragrance; attracts pollinators; foliage remains silvery

Harvest flowers as needed for fresh or dried use. Continue deadheading to extend bloom. Water only if extreme heat occurs.

5

Post-Flowering & Hardening Off

4-6 weeks (fall)

Flowers fade; seed heads form; foliage begins to prepare for dormancy or winter; growth slows

Reduce deadheading in late season to allow some seed heads to form naturally. Do not fertilize. Do not cut back severely; wait until spring. Ensure good drainage for winter moisture control.

Harvest Tips

Harvest flower spikes when 1/3 to 1/2 of the flowers on the spike are open, typically mid-morning after dew dries. Cut stems 6-8 inches above ground. Tie in small bundles and hang dry in a warm, well-ventilated, dark location for 2-3 weeks. Harvest foliage anytime during growing season for fresh use; best flavor before flowering. For dried flowers and culinary use, harvest at peak bloom.
