Growth Stages

1

Seedling

3-4 weeks

Tiny, delicate leaves emerge; very slow growth initially. Small rosettes develop with fine, narrow foliage.

Keep soil barely moist, not wet. Provide bright indirect light initially. Avoid damping off by ensuring excellent air circulation. Transplant to individual pots when first true leaves appear.

2

Vegetative Growth

4-6 weeks

Plant develops bushy form with silvery-green, narrow foliage. No flowers yet; energy focused on establishing roots and branching structure.

Reduce watering significantly; let soil dry between waterings. Provide full sun. Pinch back growing tips to encourage bushier, compact growth. Begin monthly light feeding if not in rich soil.

3

Budding & Early Flowering

2-3 weeks

Dense flower buds form at stem tips, typically purple. Plant becomes fuller and more robust. First flowers begin opening.

Continue full sun exposure. Maintain dry conditions between waterings. Avoid high-nitrogen fertilizer which promotes foliage at expense of flowers. Flowers attract pollinators.

4

Peak Flowering

6-8 weeks

Abundant purple flower spikes completely cover plant. Intense fragrance. Compact, mound-forming appearance at 12-24 inches tall.

Continue minimal watering. Deadhead spent flowers to encourage continuous blooming through summer. Can cut stems for fresh arrangements or drying. Monitor for pests.

5

Late Season & Dormancy

Ongoing through fall/winter

Flowering slows in late summer. Foliage remains silvery-green. Plant prepares for winter dormancy in cooler zones.

Do not cut back heavily before winter in cold zones; light pruning only in fall. Cut back to 6 inches in early spring after danger of hard frost passes. In warm zones (8-9), can prune lightly after flowering to maintain shape.

Common Pests

  • Hand-pick beetles, spray foliage with insecticidal soap or neem oil in early morning. Encourage beneficial insects. Rarely severe on healthy plants.

  • Increase humidity by misting foliage, spray with water to dislodge. Use neem oil or insecticidal soap if severe. Ensure good air circulation.

  • Spray with strong water stream or insecticidal soap. Encourage ladybugs and parasitic wasps. Rarely a major problem on lavender.

  • Prevent through excellent drainage and avoiding overwatering. Remove and discard affected plants. Improve soil drainage with gravel and sand amendments.

  • Prune out infected stems, improve air circulation, avoid overhead watering. Disinfect pruning tools between cuts. May require removal of severely affected plants.

Harvest Tips

Cut flower stems for fresh arrangements in mid-bloom when flowers are just fully open and fragrance is strongest, typically mid-summer. For drying, cut stems in late morning after dew dries but before peak heat. Tie in bundles and hang upside down in a warm, dry, well-ventilated location for 2-3 weeks. Harvest leaves anytime during growing season for culinary or craft use; best fragrance mid-morning after dew dries.
