Leaf curl seems to attack a number of prunus species. In Cheshire I have
seen it on blackthorn which was growing on rather marshy , presumably non
ideal, ground.
Our Cheshire peach tree used to get it most years, even though I sprayed it
with Bordeaux mixture as recommended in the week after Christmas.
Our friends in Devon have a peach tree which has suffered in the same way.
In either location new leaves grow, the blistered remains are cleaned up and
burned, and the tree continues to fruit later in the year.
It seems to be a debilitating rather than fatal condition.
Best of luck!

Anyone know what is the best treatment for "laef curl" on Plum and
Greengage trees and the best time for treatment.

Thanks.
