Troubleshooting
Nectarine Lord Napier problems — and how to fix them
Nectarine Lord Napier (Prunus persica var. nucipersica 'Lord Napier') 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.
Peach leaf curl
Nectarines are highly susceptible; rain-spread Taphrina blisters and reddens spring foliage, so cover wall-trained trees from January to May to keep leaves dry.
Fruit splitting
The skinless fruit splits with sudden rain or uneven watering, then rots; water steadily, mulch, and shelter the crop where possible.
Brown rot
Monilinia rapidly rots damaged or split fruit; remove rotting and mummified fruit immediately and keep the fan open for airflow.
Poor set in cold springs
Early blossom opens before pollinators are active; hand-pollinate flowers with a soft brush at midday in dry weather to secure a crop.
