The weeping mulberry tree (Morus alba) is a grafted cultivar of the white mulberry, native to Northern China. Originally, the tree's leaves provided food for silkworms and were an important part of China's silk industry. In the United States today, weeping mulberries are used primarily as landscaping trees. Their unusual umbrella-shaped canopy and large green leaves add visual impact to any yard. Weeping mulberries have shallow roots and can crack sidewalks and driveways if planted too closely. They reach heights of 15 feet, depending on the variety, and grow in USDA zones 4 to 8.
Select a location that receives six to eight hours of sunlight daily for your mulberry. Dig a hole with your shovel as deep as the mulberry's rootball and twice as wide. Lay the soil on a tarp spread on the ground next to the hole.
Mix three shovelfuls of compost into the soil on the tarp to lighten it and improve drainage.
Remove the mulberry tree from its pot or cut the ties securing burlap from the rootball. Set the tree in the hole, making sure it stands straight. Cut and slide the burlap from beneath the tree, taking care not to disturb the roots.
Backfill the hole halfway with soil. Fill the hole with water to remove any air pockets and allow the hole to drain completely.
Fill the hole with the remaining soil until it mounds 2 to 3 inches above the surrounding soil. Tamp down lightly with your foot to remove air pockets and prevent settling. Water the tree again for 20 minutes. Apply 3 to 4 inches of wood chip mulch around the tree to prevent moisture loss.
