Container lavender fails most often in a large wet pot, not a small dry one. Start with unrestricted drainage, mineral structure in the mix and the sunniest position available.
Use a modest pot with real drainage
Choose a pot only 2–4 inches wider than the root ball. Several large drainage holes matter more than decorative gravel at the bottom.
Terracotta dries faster than glazed or plastic pots and can help in humid or rainy climates. Never leave the pot inside a non-draining cover after watering.
- Modest diameter
- Multiple open holes
- No standing saucer water
- Stable in wind
Build air into the mix
Use a quality container mix amended with coarse mineral material appropriate to local products. The goal is fast drainage and air, not sand packed into a dense base.
Keep the woody crown slightly above the final surface and avoid moisture-holding mulch against it.
Field note: Adding a little grit cannot rescue a pot with blocked holes.
Water by dryness and prune only green growth
Water thoroughly, then wait until the mix dries substantially before watering again. Frequency changes with pot material, wind, heat and plant size.
After flowering, remove spent stems and lightly shape green growth. Do not cut into old bare wood, which may not resprout.
- 6–8 hours of sun
- Deep, infrequent watering
- Air around the crown
- Light annual pruning
Questions beginners ask
What size pot does lavender need?
Start a few inches wider than the root ball rather than using an oversized container that stays wet.
Should gravel be placed at the bottom?
No drainage layer substitutes for open holes and a well-structured mix throughout the pot.
