Dwarf weeping cherry trees may come from the nursery bare-root, burlaped or in a large pot. These trees do not like rich or heavy soil. A dwarf weeping cherry should be planted in sandy loam in an area that is protected from high winds. The soil should not be amended, as amending the soil could burn the roots. If the tree was purchased as a bare-root tree, soak the roots for at least eight hours to properly hydrate them.
Dig a planting hole that is twice as wide as the root ball. Make the planting hole no deeper than the graft union visible on the stem. The graft union is a bulge on the stem of the young tree.
Scarify the sides of the planting hole with a pitchfork or shovel. Fill the planting hole with water. Set the tree in the planting hole, turning it so that the best side is to the front. Backfill the planting hole with soil, lightly packing the soil as you backfill. Packing the soil too tightly denies oxygen to the roots and the tree will suffocate.
Create a watering ring around the perimeter of the planting hole. The watering ring helps to divert water to the outside roots of the tree, which encourages root growth and saves water. The watering ring should be about 3 inches in height. It should not come close to the base of the tree.
Mulch the dwarf weeping cherry tree with at least 3 inches of compost or pulverized bark, making sure to leave the base of the tree open. Water the tree with at least an inch of water.
Water the dwarf weeping cherry once a week with at least an inch of water. Deep watering promotes root growth and plant health, whereas shallow watering promotes a shallow root system and a tree that is easily uprooted.
