Cornus kousa 'Miss Satomi' problems — and how to fix them
Cornus kousa 'Miss Satomi' (Cornus kousa 'Miss Satomi') 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
Dry soil, drought or harsh sun brown the leaf margins; keep the rootzone evenly moist, mulch well and give afternoon shade in hot climates.
Slow to flower
Young trees may take a few years to bloom freely; this is normal establishment behaviour, not a fault, so be patient and avoid overfeeding with nitrogen.
Iron chlorosis on chalk
Yellowing leaves with green veins on shallow alkaline soil; acidify the soil, apply chelated iron, or grow in a container of ericaceous-leaning mix.
Powdery mildew
White coating on leaves in humid, crowded conditions; improve air movement, avoid overhead watering and remove badly affected foliage. Kousa types are more resistant than native flowering dogwood.
