When buying a Willow, the best option is to choose a local nursery or grower. While they may not have the particular type you’re looking for, it’s always a good idea to check.

Native Region and Habitat Growing Needs of Willow Trees
Three of the largest willows are the black willow, the brittle willow, and the white willow. They grow to 65 feet or more.
The first grows in North America while the other two are Eurasian but widely naturalized. All three willow varieties are common in lowland areas.
It’s best to find a growing site that receives anywhere from full sun to partial shade.
The soil needs to be moist, well-draining, and a bit acidic. It’s not advised to plant a willow near underground power lines or sewers because weeping willows have long roots.
How to Grow Willow Tree
When learning how to grow a willow tree, the planting practice is very similar to other large trees. Dig a hole twice the width of the root ball. Place the root ball in the hole while gently separating its roots.
Fill the hole halfway with the soil and then pour two gallons of water into it. Fill the rest of the hole and tamp down to remove the air bubbles.
Willow trees grow best when planted by ponds or streams.
While willows tolerate most types of soil, be it alkaline, sandy, or clay-based soils, their preference is moist, well-draining, and slightly acidic soils. If soil is too alkaline, it can be made more acidic by adding sulfur.
Willows must be thoroughly watered once a week for the first year after planting. (or, even better, use a circular water hose to distribute water on a daily basis, as needed to keep the soil moist). After that, the tree needs just enough water so that the soil doesn’t dry out. Test the moisture level by sticking a finger or two into the soil. If the top two inches are dry, the tree needs to be watered.
Willow trees don’t need fertilizer to be healthy. If the leaves look pale, a balanced fertilizer may be added come spring.
Pruning Willow Trees
A willow tree needs to be pruned when it’s young to ensure there is one central trunk. It’s advisable to snip all its branches in late winter or early spring. That will encourage new branches to grow and invigorate the tree.
Weeping willows have many pest and disease issues because of their edible bark. The tree can obstruct underground pipes and powerlines. They need to be planted at least fifty feet away from a house.
How to Identify Willow Tree Types (Willow Tree Identification Tips)
The most identified willow tree varieties are the weeping willow and the pussy willow. A few more varieties grow in Europe, North America, and Asia.
Willow trees are best known for their shapely and round canopies. It’s sometimes hard to tell the difference between species, but a closer look does reveal their various characteristics.
