Yellow plum/damson leaves
I planted maiden Merryweather Damson and Czar Plum trees in March this year and they seemed to take well and flowered well. I dug in a little compost at planting time, staked the trees and have kept them well watered during what few dry spells we have had this summer. Despite this they have both put on very little growth and the leaves are quite sparse and yellow. Does anyone know what might be causing this and what/ if anything can I do? I plated two maiden apple trees at the same time and both have flourished in their first season.
