Establishment
2-4 weeksYoung transplants with limited foliage; early root development. Plants appear delicate with sparse leaves.
Water lightly but consistently. Protect from extreme heat and wind. Ensure excellent drainage. Avoid fertilizing; lavender prefers poor soil.
Vegetative Growth
4-8 weeksBushy foliage development with silvery-green leaves becoming more dense. Plant increases in height and width.
Maintain moderate watering. Begin light shaping by pinching back tips to encourage bushiness. No fertilizer needed; can reduce growth.
Pre-Flowering
2-3 weeksFlower buds begin forming along stems. Plants appear fuller with visible bud spikes emerging from the foliage.
Reduce watering further. Do not fertilize. Ensure maximum sunlight. Stake tall plants if needed in windy locations.
Flowering & Blooming
6-10 weeks (can repeat with deadheading)Pure white flower spikes fully open along stem tips, creating striking contrast with silvery foliage. Heavy bloom period.
Deadhead spent flowers to encourage continuous blooming. Water only when soil is dry. Enjoy fresh or dried flowers; cut for arrangements.
Post-Bloom & Dormancy
3-5 monthsFlowering slows; some flowers fade to pale tan. Foliage remains attractive through winter. Plant enters semi-dormant state in cold climates.
Cut back lightly after bloom (not more than 1/3 of plant). Minimal watering in winter. Light pruning in early spring before growth resumes.

Harvest Tips
Harvest flowers at peak bloom (mid to late morning after dew dries) for strongest fragrance. Cut stems 6-12 inches long just below flower spikes. For drying, harvest just as flowers begin to open; bundle loosely and hang upside down in a warm, dark, airy location for 1-2 weeks. Deadhead regularly during bloom season to promote continuous flowering.
