Troubleshooting
Peregrine Peach problems — and how to fix them
Peregrine Peach (Prunus persica 'Peregrine') 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 dominant UK peach problem; rain-borne Taphrina blisters spring leaves, so cover wall-trained trees from January to May to keep the foliage dry.
Brown rot
Monilinia rots ripening fruit through wasp or split-skin wounds; remove and bin affected and mummified fruit and prune for an open, airy canopy.
Frost on early blossom
Peregrine flowers early and can lose blossom to spring frost; drape fleece on cold nights and hand-pollinate under cover to secure fruit set.
Overcropping
Sets fruit heavily, giving undersized fruit and strained branches; thin fruitlets to about one every 15 cm after the natural June drop.
