I have a rhodo which was under the canopy of a diseased plum tree which has recently been removed. I live in West Vancouver and the tree is in my front yard, facing northwest. It now receives more sunshine and needs to be pruned because many of the branches are bending over, some touching the ground. I am afraid that they will crack or break due to the weight of the snow come winter. I’d like to know how I should prune the tree, when and because of the increase in the amount of sunshine it now receives, what kind of mulch I should lay beneath it?
