Care Instructions

Watering

Water newly planted lavender weekly for the first month, then every 2–3 weeks. Once established (1 year), water only during prolonged drought. Lavender is more often killed by overwatering than drought.

Sunlight

Absolute full sun (6–8+ hours). No exceptions. Even 4 hours of shade causes weak growth and poor flowering.

Soil

Fast-draining, lean, sandy or gravelly soil is essential. pH 6.5–7.5. Add grit or coarse sand to heavy clay soil. Never amend with compost — lavender hates rich soil.

Seasonal Guide

Best Planting Time

Spring after last frost. Allow the full growing season to establish before winter. In mild climates, fall planting works well.

Bloom / Growth Season

Peak bloom May–July. Shear back by one-third immediately after blooming to encourage a second flush and maintain compact shape.

Dormancy

Semi-evergreen. Mulch with gravel (not bark) around base in cold winters. Never cut back hard in fall — wait until spring to see what survived.

Common Problems & Solutions

Root rot / Phytophthora (sudden collapse)

Ensure perfect drainage — this is non-negotiable. Raise planting bed 6–12 inches. Once root rot sets in, the plant cannot be saved.

Woody, sparse center (aged plant)

Cannot rejuvenate severely woody lavender. Replace every 5–8 years. Annual light shearing after bloom prevents this.

Xylella or shab disease (gray, dying stems)

Remove and destroy affected plants. Do not replant lavender in the same spot for 3+ years.
