The Q&A Archives: lavendar plant w/browning stems

Question: My lavendar plant is on the west side of the house (however does have shade at late afternoon)...not doing well. Showing signs of browning leaves (stems?) up the plant. Want to try and save the plant. Do I need to replant to different location/fertilize?

Answer: Lavender does best in an open situation with good air circulation, full sun, and perfect drainage. It also prefers a rather dry soil on the alkaline side. As a rule it is not a heavy feeder. Summer browning is usually do to either overwatering or to fungal problems caused by high humidity combined with poor air circulation.

While it is possible that moving it would help, particularly if it is crowded or the house is interfering with air circulation, do keep in mind that transplanting is stressful for the plant and could kill it if it is already severely stressed.

In general it's also a good idea to avoid overhead watering. In either case, trimming it back by at least half immediately after the first flush of bloom can also help reduce browning later in the season.

Good luck with your lavender!
