Using your small loppers, cut off the terminal branches of young plants to remove fruit buds. Young (1- to 3-year-old) plants shouldn't be allowed to bear fruit, since it can stunt plant growth and reduce future yields. You don't need to do any additional pruning on young bushes.
Use your long-handled pruning loppers to prune all low-spreading branches, as well as weak canes toward the center of the plant.
Prune any diseased or infested canes, cutting below the point of damage.
Thin the top of the plant by pruning 20 percent of the shorter, thinner shoots.
