The Kwanzan cherry (Prunus "Kwanzan") is a deciduous flowering tree that offers year-round interest. New foliage appears in a striking bronze color before turning green. In the fall the foliage turns from yellow to burnished brown. Although the Kwanzan cherry does not produce fruit, it bears bright pink, double flowers in the spring. Kwanzan cherry trees only live 15 to 25 years and are hardy in USDA zones 5 to 9.
Choose a planting area that receives full sun. The Kwanzan cherry tree is not particular about soil and can even be planted in clay.
Dig a hole that is the same depth at which the Kwanzan cherry tree has been growing. If you purchased a potted tree, measure the height of the pot and dig the hole to that depth. If the tree is bare root, measure the distance from the bottom of the rootball to the point where it joins the trunk and dig the hole to that depth. The hole should be three times as wide as the rootball.
Use a garden fork or pitchfork to scrape the inside walls of the hole. This makes it easier for the tree's roots to penetrate the soil.
Remove the tree from the pot and place the roots into the planting hole. Use your hands to spread them out in all directions. Fill the hole one-third of the way with soil and then fill it completely with water. When the water drains, finish filling the planting hole with soil. Use your feet to lightly tamp the soil around the base of the tree.
Add a 3-inch layer of mulch to the soil around the base of the tree. Keep it 3 inches from the trunk and spread it in a 3-foot radius around the tree.
Water the tree until the top 6 inches of soil is wet.
