I have a plum tree in my garden that was healthy last year, but this year all the plums have split and the leaves look dry and curled up. Any idea what could be wrong?

Phil Dudman says

Splitting commonly occurs in fruit when watering is erratic, such as when a long dry spell is followed by a soaking. Give trees a regular deep watering during dry periods. The leaves look like they have had a visit from plum leaf-curling aphids. Look for them when the tree produces a new flush of growth, and dislodge them with a sharp spray of water or apply a soap spray.
