1. Not Enough Sun
- Lavender needs at least 6 hours of full sun (ideally more) to flower profusely.
- Fix: Move the plant or trim back shading neighbors. A south- or west-facing spot is ideal.
2. Too Much Water or Poor Drainage
- Waterlogged roots lead to poor bloom and die-back.
- Fix: Plant in well-draining, sandy soil. Water only when soil is dry to the touch. For pots, always empty saucers and use gritty compost.
3. No or Incorrect Pruning
- Lavender flowers on new growth, but unpruned plants become woody and bloom less.
- Fix: After flowering, prune back stems by about one-third (not into old, leafless wood). In spring, shape if needed.
4. Rich Soil or Over-Fertilizing
- Lavender thrives on lean, slow-draining soil—too much fertility means leaves, not blooms.
- Fix: Avoid manure or heavy feeding. Sandy, slightly alkaline soil is best.
5. Wrong Variety or Climate
- Some lavenders (Spanish, French) don’t thrive in cold/wet climates.
- Fix: English lavender (‘Hidcote’, ‘Munstead’) is the most reliable for cooler areas.
6. Young Plant or Recent Planting
- Many lavenders don’t bloom much in their first year.
- Fix: Be patient—the best display comes in years 2–3.
7. Root Rot or Disease
- Signs: Wilting, black stems, yellowed or dying leaves.
- Fix: Improve drainage, cut out damaged parts, and replant if necessary.
