Growing a weeping willow tree is relatively easy. Given proper care and adequate drainage, these trees are adaptable to most types and pH levels of soil. Choose an area that gets full to partial sun, as weeping willows do not like full shade. While weeping willows are young, they are more susceptible to pests such as deer. However, if you keep such pests away, willows grow quite quickly. Water, fertilize, and prune them to ensure strong, centralized, vigorous growth over the course of their 30-year life span.
Select an area that receives good drainage and full to partial sunlight. Do not select a site that is close to underground utilities (water, sewer, electrical, or phone lines). As they grow, willow roots will expand to about 3 times the circumference of the canopy of the grown tree.
Dig a hole with your shovel that is twice as wide and twice as deep as the root ball of the sapling.
Place the sapling in the hole, and cover the root ball completely with soil. Make sure to tamp the soil down firmly so that there are no air pockets around the roots. Air pockets can cause the roots to dry out and die.
Apply a good all-purpose fertilizer to the soil around the tree as the package instructs.
Water the soil around the tree regularly. Do not water the base of the tree directly, as this can encourage root and trunk rot. As the tree grows, this will become less of a danger.
Apply deer repellant to the top of the sapling as the package instructs, if deer are a problem in your area.
Prune your willow vigorously in its youth. Development of a strong central trunk is essential to its well being. Prune away any smaller trunks that try to form so that this strong central trunk establishes itself early on.
