Troubleshooting
Sweet Cherry 'Stella' problems — and how to fix them
Sweet Cherry 'Stella' (Prunus avium 'Stella') 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.
Fruit splitting
Ripening cherries crack when heavy rain or watering follows dry conditions. Maintain even soil moisture and consider a rain cover or wall-trained position in wet climates.
Bird damage
Birds strip ripening cherries within days. Net dwarf and fan-trained trees as fruit colours; the compact Gisela 5 form makes netting practical.
Brown rot
Fruit rots with brown patches and buff spore rings, worse in warm, wet weather. Remove infected and mummified fruit and prune for airflow.
Cherry blackfly
Aphids curl and pucker the leaf tips in spring, weakening growth. Tolerate light attacks for predators or wash off; severe infestations check young trees.
