Azalea 'Weston's Flamingo' problems — and how to fix them
Azalea 'Weston's Flamingo' (Rhododendron 'Weston's Flamingo') 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.
Chlorosis (yellow leaves)
Caused by alkaline soil preventing iron uptake. Test soil pH and apply chelated iron or ericaceous compost.
Bud blast
Buds blacken and fail to open, often caused by the fungus Pycnostysanus azaleae spread by rhododendron leafhopper. Control leafhopper populations and remove affected buds.
Vine weevil damage
Larvae eat roots; adults notch leaf margins. Apply nematode treatment (Steinernema kraussei) in late summer to target larvae in the soil.
Powdery mildew
White powdery coating on foliage in late summer due to poor airflow. Improve circulation and apply a sulfur-based fungicide if severe.
Root rot (Phytophthora)
Caused by waterlogged soil. Ensure sharp drainage and avoid overhead irrigation directly at the crown.
