A weeping, flowering cherry tree is one of the most beautiful of all of the ornamental trees. We bought my mother-in-law one for Mother’s Day many years ago. She was so excited. Being a certified nurseryman, I planted the tree exactly the way it should be done. The next year it bloomed nicely—and even better the next year.
However, after about four or five years, my mother-in-law called me right after the tree had bloomed. She expressed concern because the tree barely bloomed at all that spring. In fact, she said it was pitiful. The next time we went for a visit, I took my pruning clippers and small pruning saw. While she watched, I got the ladder and went to work. Several times I heard her say, “O my,” and “O dear.”
Correct, effective pruning is different than just “shearing” the tree to look like a lollipop. There are two basic types of branches that need to be removed. The first is a branch that is growing the wrong direction. These branches rub the other branches and can cause disease. They also block out the sunlight that is needed for flower buds to form.
The other type of branch to prune is a “sucker” branch that shoots out beneath the graft. These branches are incredibly dangerous to the life of the tree. They will draw all of the strength and energy from the tree into themselves, and the tree will often die—but only above the graft, which is where the blooms grow. read more
