Globe Willows are a very fast growing shade tree and one of the first trees to leaf-out in the spring. Small tassels are followed by long slender leaves. Really a beautiful tree when taken care of properly.
The tree is a very fast grower and gets very large, 30 to 50 feet high. They require full sun and water use is moderate to high.
Globe willows have several inherent problems. The tree will drop leaves and branches even when healthy, when stressed it will drop even more.
This is a natural process called Cladoptosis and can be a very messy problem, which happens year-round.
High winds will also break branches, as the tree has very soft wood.
Insects and diseases seem to plague the Globe Willow tree more than others.
Borers love the tree, as well as aphids and spider mites.
The disease "Frothy flux" runs rampant in willows and the fungus disease "Cytospora canker" is very devastating to Globe Willows.
Stress tends to invite these diseases, so proper care is essential for a well-shaped, healthy tree.
We don't recommend the Willow tree for the desert Southwest landscape, because of all these issues.
