Q.trimming a weeping cherry tree
I have a weeping cherry tree (grafted type) at least 10 years old. it is starting to be odd shape and I want to know if I trim some of the larger branches, about 1 1/2 inch, will they sprout again from the ends or become a stump type end?

The branches won't sprout directly from the ends where you pruned them, but they will put out more side branches from buds closer to the trunk. Proper pruning can correct your tree's shape. It may be best to contact an arborist or other professional for help. This article will help you learn about weeping cherry tree pruning:
