|A 17 year old Bradford Pear tree - suckers are coming up everywhere. With the repeated cutting of the suckers, it has created massive
|Pear trees tend to send up suckers for no apparent reason at all. Usually it's because the roots are close to the surface of the soil. When a tree is young you can encourage deep roots with infrequent but deep watering. As the tree matures the roots will remain below ground. When a tree is water stressed it will send roots close to the soil surface to take advantange of rainfall and of water applied to a nearby lawn or flower bed. There's not much you can do to stop the suckering now that the roots are at the soil surface. There is a product called Sucker Stopper that is supposed to stop the root suckering. You should be able to find it at your local garden center. If not, you can find it online from the manufacturer. Water sprouts in the top of the tree can grow if you prune while the tree is actively growing. Try pruning them off in December or January when your tree is resting. With any luck no new suckers will develop. Wish I had more information to share. Best wishes with your Bradford Pear.
