Troubleshooting
Mountain Laurel 'Olympic Fire' problems — and how to fix them
Mountain Laurel 'Olympic Fire' (Kalmia latifolia 'Olympic Fire') 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.
Leaf scorch and chlorosis
Yellowing between veins signals alkaline soil or hard water locking out iron. Grow in acidic soil, water with rainwater and feed with ericaceous fertiliser.
Poor flowering
Often from too much shade or summer drought stressing the buds. Give dappled light and steady moisture, and deadhead spent flowers to redirect energy.
Leaf spot fungi
Purple-bordered spots on foliage in wet, crowded conditions. Improve airflow, clear fallen leaves and avoid overhead watering.
Root stress in heavy or dry soil
The shallow fibrous roots suffer in waterlogged clay or baked dry soil. Plant in well-prepared humus-rich soil and mulch to buffer moisture and temperature.
