Troubleshooting
Asian Pear problems — and how to fix them
Asian Pear (Pyrus pyrifolia) 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.
Fireblight susceptibility
Asian pears are notably prone to fireblight, with shoots blackening as if scorched. Cut well below affected wood into healthy growth, disinfecting tools, and avoid heavy nitrogen feeding.
Frost damage to early blossom
Early flowering risks losing crops to spring frost. Choose a sheltered, slightly elevated site and protect blossom with fleece on frosty nights.
Small, gritty fruit without thinning
Heavy natural set gives many small fruit. Thin to one fruit per cluster in early summer for the large, sweet, crisp pears the type is grown for.
Pear scab and codling moth
Scabby blotches in wet springs and maggoty cores from codling moth. Remove fallen leaves, prune for airflow and use pheromone traps.
Prevent asian pear problems before they start
Most asian pear issues are care-mismatch, not bad luck. Dial in the basics:
