This years crop of cherries is the best ever,though I’ve never picked them before. How can I tell if they are edible type?The tree is green leaved with white cherry blossom in Spring, as distinct from maroon leaf type tree.I’m keen to pick and use them if edible. Secondly, the same tree is c.14 ft high, with c. 12ft.span , and I’d like to know how and when to prune it correctly.Many Thanks , DOCC.
