Learn how to make a tree stump planter and make use of an old stump that you want to get rid of. Hollow it out from the center using whatever the sharp tool you have like a mattock, an ax (axe) or a chainsaw. Work on to make a hole that is 4-8 inches deep and has at least 3 inches border. With the help of a drill, make drainage holes into the side of the stump so that they slope down towards the ground and water will drain from them easily. With all the previous three steps done, your DIY tree stump planter is complete. Now fill it with well draining potting soil that is rich in compost and plants your favorite flowers in it.
