Weeping cherry trees are popular landscape trees for their beautiful pink flowers that cover the tree in the spring. Because of their popularity, the trees are readily available in most nurseries and garden centers. Weeping cherry trees are normally grafted to a root stock of the species that is hardier than the weeping form, about 6 feet from the ground. These trees are normally 20 to 30 feet tall with a 15- to 25-foot spread. Purchase the tree in a pot from a nursery for the healthiest trees with the best chance of survival.
Stake the tree for the first year to prevent them from being windblown or leaning to one side from heavy growth. Use landscape ties and tie loosely, checking on them every 2 months to make sure they have not become too tight.
Water the tree twice a week for the first two weeks after planting. Irrigate to keep the soil moist, but not soggy, for the first growing season. Once the tree is established, once a week watering will be needed when there has not been sufficient rain.
Apply a flowering tree fertilizer once you start to notice new growth the first season and each spring in the following years. Follow manufacturer's directions on the amount to apply per size and age of the tree.
Spread a 4-inch layer of shredded bark mulch under the canopy of the tree. The mulch will keep the weeds from growing and help to retain moisture. As the mulch decomposes it supplies needed nutrients to the soil. Re-apply the mulch in the fall and spring to keep it at 4 inches. Keep mulch 3 inches from the trunk of the tree.
Place a 2-inch layer of compost over the mulch in mid-summer. Regular watering will leach the compost through the mulch and supply the soil with nutrients for the tree and keep the soil from compacting.
Mix 1 part bleach to 10 parts water in a bucket to sterilize your pruning shears before using them on the tree. This will keep you from spreading any disease from another tree to your weeping cherry.
Cut off dead or damaged branches whenever they are noticed. Grafted trees must have all branches and water sprouts cut off at the trunk whenever they grow from beneath the graft line. These branches will grow straight up as they are not from a weeping form of tree.
