Troubleshooting
Peach Rochester problems — and how to fix them
Peach Rochester (Prunus persica 'Rochester') 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
The main pest of UK peaches; rain-borne Taphrina blisters leaves in spring, so cover wall-trained trees from midwinter to late spring to keep foliage dry.
Brown rot
Monilinia rots ripening fruit, entering through wasp or split-skin wounds; remove and bin rotted and mummified fruit and prune for an open canopy.
Poor pollination in cold springs
Early blossom may open before insects are active; hand-pollinate with a soft brush at midday in fine weather to ensure fruit set.
Overcropping
Sets too heavily, giving small fruit and limb breakage; thin fruitlets to roughly one every 15 cm after the June drop.
