The Kwanzan (Prunus serrulata) is an ornamental, pink-flowering cherry tree that grows well in U.S. hardiness zones 5B through 9A with sunny locations and well-drained soil. The average height and width of the Kwanzan is 15 to 25 feet. Early summer through early fall is the ideal time for planting a Kwanzan tree.
Mix one part organic potting soil with two parts sand in a large wheelbarrow. Add 1 tablespoon of 10-10-10 fertilizer per .01 pound of soil mixture.
Measure the depth and width of the Kwanzan tree root ball and multiply both of these measurements by three. For example, if the root ball is 2 feet deep and 3 feet wide, the results would be 6 and 9. Dig a hole the size of this measurement, then add the soil mixture from step 1 until the hole is a quarter full.
Remove the Kwanzan tree from the original potting container or cut the ties of the burlap casing. Place the tree into the hole and continue filling the hole with the soil mixture. Tap the dirt as you go to make certain it is firm around the root ball.
Water the newly planted Kwanzan tree until the ground is saturated but not soggy with standing water.
