Troubleshooting
Western Bog Laurel problems — and how to fix them
Western Bog Laurel (Kalmia microphylla) 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.
Drought and root death
The single most common problem in cultivation; the plant is acutely sensitive to drying out and can die rapidly if soil moisture fails. Grow only in reliable bog or pond-edge conditions with continuous moisture.
Alkaline soil chlorosis
Yellowing and stunting result quickly when pH rises above 6 or when calcium carbonate is present; use only rainwater for irrigation, acidify with sulphur if needed, and never apply lime to adjacent beds.
