Some varieties of trees can sow themselves energetically by dropping seeds onto the soil. If you do not keep a careful watch over your landscape, a tree sapling might begin growing in an undesired spot. Often by the time you notice the sapling, it is large enough to prevent you from simply pulling it up out of the soil. When this occurs, you must remove a sapling tree by extracting it from the growing location.
Create four or five superficial wounds just slightly deeper than the bark of the sapling with the pruning saw or lopping shears. Space the notches between 3 and 4 inches apart and place them at various spots along the sapling trunk.
Apply the glyphosate herbicide to the notches with the paintbrush. Coat each notch generously with glyphosate to enable the herbicide to soak into the sapling's inner system. The tree will transport the glyphosate down to the roots of the sapling to kill the sapling.
Wait and watch the progress of the glyphosate on the sapling. Over the next one to two weeks, you should notice the sapling begin to wither and die. If the tree does not begin to visibly die within this period, apply the glyphosate a second time.
Cut down the sapling with the pruning saw or lopping shears just above the soil level after the tree withers and dies.
