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.
