The 411 on Weeping Willow Tree Care

Weeping Willow Tree

If you want a truly magical tree that adds whimsy, texture, and shade to your landscape design, the weeping willow is a great option to consider. Not only does it offer an elegant appeal that adds value to your home, but the tree's potential 40-foot height and 35-foot spread ensure you will have definition and shade around your home for many years to come.

Of course, proper care of your tree is necessary if you want it to look appealing and grow in a healthy manner. This guide and tree-care professionals will help you maintain your weeping willow tree.


Fertilizing may not be the most important part of maintaining a weeping willow tree, but it is still helpful if you want the tree to grow efficiently and as healthy as possible.

The tree's roots are quite grand and complicated, spreading out far into the ground below. Instead of applying the fertilizer directly to the tree, apply the fertilizer to the soil to ensure that the nutrients reach the roots.

Many people have their soil tested before purchasing a fertilizer, since this can help determine what nutrients are lacking. However, a balanced 20-20-20 fertilizer containing equal parts of nitrogen, phosphorus, and potassium, is a good option.

After applying the slow-release fertilizer to the soil of your weeping willow, water the tree and ground thoroughly.


Pruning is the most important part of caring for your weeping willow tree. It is necessary for a few reasons, including improving the tree’s look, promoting new growth, and preventing diseases and infections.

Late winter is the best time to prune your weeping willow. Since the tree will be dormant during this time, any wounds will heal before new growth appears in the spring season.

The classic weeping willow design is classic and beautiful, but it requires a good amount of upkeep. The limbs can grow out so wide that they hang toward the ground. The weight of these low-lying limbs can pull down the tree's canopy, affecting its look and increasing the risk of limbs breaking off.

Pruning off branches and foliage that hang too close to the ground will save your tree from damage. Avoid cutting off any branches that are leaders, or the strongest branches of the tree. Focus on cutting branches that have v-shaped junctions instead, since these branches will most likely eventually break and fall off.

Finally, you should also prune off any branches that are broken and discolored. This will prevent limbs from breaking and falling off onto your home, vehicle, or other structure. In addition, removing discolored or decaying branches can stop pests and diseases from spreading through the rest of the tree.


While rare, certain diseases can be life-threatening to your tree. Knowing the signs that your tree is in distress is essential for early diagnosis and effective treatment.

Willow scab and black canker are two common diseases that harm weeping willow trees. Both are caused by a fungus that attacks the foliage first, causing red, black, or brownish spots on the leaves. Eventually, the fungus can spread into the branches and trunk, causing severe damage.

Although not as serious, powdery mildew can affect your weeping willow tree. As the name suggests, this fungal disease causes a white or grey powdery residue on the surface of the leaves. It will usually not kill the tree, but it can cause early defoliation.

No matter which type of fungus is threatening your weeping willow, applying a fungicide as soon as you notice the signs is imperative. Removing any limbs and foliage that show signs of the disease is also necessary to stop the infection from spreading and killing your tree.
