  • Why Should I Spray My Tree? Many trees produce suckers every spring. Even though you cut them back, the suckers will continue to come back all summer long, which can require a lot of pruning. One application of Sucker-Stopper RTU can prevent growth of suckers. After pruning, many trees will put out suckers around the pruning wound. One application of Sucker-Stopper RTU after pruning will prevent these suckers from returning. Thoroughly cover the primary wound, or where the existing sprouts have been removed. Be sure to treat before new growth suckers are 10 inches in length. The earlier you treat, the better the results. Control should last about 3 months, depending on the species.
