Suckers, also known as “water sprouts,” are notorious for sprouting from the base and crotches of some trees. They grow fast and straight. These succulent shoots are more susceptible to disease and insects. Prune these suckers on a regular basis. They occur most frequently on Canada Red Cherry, crab apples, and many other trees. Over-fertilization may trigger the production of sprouts.
Don’t give these suckers a break!
