Caring for Willow Oak

Willow Oak Trees are easy to grow and extremely adaptable. Spring and Fall are ideal times to plant. However, if you avoid freezing and hot temperatures you can plant your Oak tree almost any time of the year.

Willow Oaks thrive in full to part sun and are adaptable to any soil, even tolerating wet areas. These trees are even drought tolerant once established. Water deeply twice weekly for the first 3 months after planting. This helps the roots establish properly. Add a layer of 2 to 3 inches of mulch when planting to help keep the soil moist. Do not allow the mulch to touch the trunk as this increases the chances of pests and disease. Fertilize in early spring with a basic slow release fertilizer. Willow Oaks don't generally require pruning, but, if needed, prune when they are dormant in winter or early spring to remove any dead, dying, or crowded branches, or to maintain shape. The Willow Oak is pest and disease resistant, as well as pollution and salt tolerant.

Willow Oaks only rarely have issues with pests or disease. Occasionally, Scale and Mites can infest these Oaks. You can treat these pests naturally with horticultural oil, neem oil, or insecticidal soap. For severe infections you can use pesticides like carbaryl, also known as Sevin. In extremely humid areas, fungal issues can arise. Generally, treating after infection isn't extremely effective, so if you have problems yearly treat in early spring with fungicides to prevent infection. Neem Oil is an organic method of treating some fungal diseases and pests. It can be effective, but the entire tree must be coated in order for this method to be effective.

Landscape ideas

The Willow Oak provides excellent shade with its dense and broad canopy.  Be sure to provide your oak tree with plenty of room to grow.  Reaching heights up to 60 feet and a width of about 40 feet, a full grown Willow Oak is a substantial tree.  This shade tree is ideal to be the main, focal tree in your yard.  If you have a large yard or piece of land, oaks are great for planting in a row to provide shade in the summer.  And they look beautiful too! The Willow Oak offers rich, orange color in fall that will liven up your landscape.  Plant about 18 feet apart when planting in rows.
