Troubleshooting
Nanking Cherry problems — and how to fix them
Nanking Cherry (Prunus tomentosa) 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.
Poor fruit set
Largely self-incompatible; plant two or more genetically different seedlings nearby so bees can cross-pollinate, or expect sparse crops.
Brown rot (Monilinia)
Blossoms and fruit turn brown and mummify in wet springs; remove mummies, thin for airflow, and avoid overhead watering.
Short-lived stems
Individual canes decline after 10-15 years; renew the shrub by cutting out the oldest stems at the base to encourage vigorous replacements.
Bird predation
Ripe cherries are stripped fast by birds; net plants or harvest promptly as fruit colours.
