Troubleshooting
European Beech problems — and how to fix them
European Beech (Fagus sylvatica) 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
Margins brown in hot sun or wind; give afternoon shade in warm climates and keep moisture steady.
Beech woolly aphid
White fluffy colonies on shoots and leaf undersides cause distortion and sooty mould; treat with insecticidal soap and improve airflow.
Drought sensitivity
Shallow roots make beech intolerant of dried-out soil; a bonsai that dries fully may not recover. Water consistently in summer.
Powdery mildew
White coating in humid, crowded conditions; thin the canopy and avoid wetting foliage in the evening.
