A member of the rose family, the weeping cherry (Prunus subhirtella 'Pendula') is a deciduous tree, native to Japan. Weeping cherry is considered a small tree, growing to heights of 20 to 30 feet with a 15- to 25-foot spread. When choosing a site to plant the tree, make sure that it gets full sun, with afternoon shade in the warmer regions. Weeping cherry tree is hardy to USDA zones 5a through 8b.
Dig a hole 1 inch shallower than the pot in which the weeping cherry tree is growing, but three times the width. Use a pitchfork or gardening fork to scrape the sides of the hole to make it easier for the roots to penetrate the soil.
Remove the weeping cherry tree from the pot and gently loosen the roots before placing it in the hole. Throw a shovelful of soil over the roots and then fill the hole halfway with water. When the water drains, fill the hole three-fourths of the way with soil and again fill it with water. Allow the water to drain and finish filling the hole with soil. The water helps remove air pockets within the soil that will dry the tree's roots.
Water the tree until the water forms a puddle around the base of the tree.
Pour 2 to 3 inches of mulch onto the soil and, beginning 6 inches away from the trunk, spread it completely around the tree.
