Hi,

I planted a peach 'Peregrine' and a nectarine 'Lord Napier' tree in
Spring
2002. All through 2002 I didn't get a single leaf. This year, the trees
are
covered in leaves and seem to be growing well.

However in the last couple of weeks I have noticed bright red
"blisters"
appearing on the leaves of the trees. All the blossom was killed in our
late severe frosts.

Does anyone know what caused the red blisters? Will the trees live?

It's Peach Leaf Curl, a fungal disease. It is spread by spores that live
in the soil during winter and are 'splashed' onto the leaves in rain. It
will not do a lot of harm, the leaves usually drop off and can then be
collected and burnt, or you could pick them off. Protecting the tree in
Spring with a fleece cover is supposed to help. I have noticed that mine
has much less of the disease this year, but have no idea why. It won't
stop it fruiting, and later leaves are always OK.

I've read that it is best treated as it can weaken or kill the tree
