problem with stella and sunburst cherries on gisela / colt rootstocks. I live in W. Yorks on heavy clay. cherry trees seem to grow well here. I bought 2 trees 2 years ago. the trees fruit fine and do not appear to have any infestation. However most of the year, the leaves fold in half along the main vein of the leaves leaving mostly the underside showing, which makes the trees look drab. They look thirsty and the leaves open up a bit if the tree is drenched with water. Is this an effect of the dwarfing rootstocks? If so, will the trees always be like this?
