Troubleshooting
Crowberry problems — and how to fix them
Crowberry (Empetrum nigrum) is generally low-drama, 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 poorly drained sites
Despite tolerating moorland moisture, standing water around the crown causes root rot; ensure lateral drainage exists and raise plants on a gritty mound if planting in heavy soils.
Chlorosis on alkaline soils
Yellowing of young foliage indicates an elevated soil pH; treat with sequestered iron and acidify the growing medium with sulphur chips or switch to ericaceous compost.
