Dallas Mavericks – Threes for Trees Planting 032919 Digging the soil to make space for a tree. It takes a lot of shovel work to make space for a tree. It takes a team to dig a hole. You want to make sure the hole is deep enough. Tamping down the dirt before planting the tree. Rolling the tree to the hole making sure you don’t damage the tree. Filling in the hole after the tree is planted is also important. Putting mulch around the tree to create a well for when the tree is watered. Moving the mulch to make sure it does not touch the tree trunk. After the tree is planted, it needs to be watered deeply. A group shot of the children and members of the Dallas Mavericks.
