Troubleshooting
Quince 'Leskovac' problems — and how to fix them
Quince 'Leskovac' (Cydonia oblonga 'Leskovac') 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.
Quince leaf blight
Diplocarpon fungal leaf blight is the main problem, causing brown-spotted, distorted, falling leaves and blemished fruit in wet seasons. Rake up fallen leaves, prune for airflow and avoid overhead watering.
Fruit too hard to eat raw
'Leskovac' is among the more palatable quinces but is still essentially a cooking fruit; raw it is astringent and gritty. It excels cooked into jelly, paste and preserves.
Fireblight
Like other pome fruits quince can suffer fireblight, with blackened, hooked shoot tips. Prune out affected wood well below symptoms, disinfecting tools between cuts.
Codling moth and brown rot
Fruit can be tunnelled by codling moth larvae or develop brown rot. Use pheromone traps, remove mummified fruit and clear windfalls to break the cycle.
