Troubleshooting
Sea Wormwood problems — and how to fix them
Sea Wormwood (Artemisia maritima) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot in clay or wet soils
This coastal species requires near-perfect drainage. Inland planting in heavy soils almost always results in failure. Use raised beds with a grit and sand mix for inland trials.
Leggy growth
Without annual trimming, plants become open and woody at the base. Clip by one-third in early spring before new growth and again lightly after flowering to keep a neat dome.
Spider mite in hot, dry conditions
Despite liking dry conditions, the fine foliage can host spider mites in hot summers. Mist foliage with water in the evening during extreme heat; avoid indoor overwintering in low-humidity rooms.
