Weeping Pussy Willow
It’s best to prune your Weeping Pussy Willow tree when it is young and hasn’t grown overly dense. Cutting off the lower limbs will allow new branches to sprout. This will improve the overall health of the tree and produce long straight branches. Trimming during its younger years will also help it produce fewer branches that hang over the lair.
Weeping Pussy Willows are susceptible to fungal diseases. These can cause brown patches on the leaves or wilting branches. If left untreated, they can stunt the plant and die. To treat these diseases, use a copper fungicide. Another fungal disease is twig blight, which causes the twigs to become black and develop cankers. Powdery mildew, which leaves a white film on the leaves, is another common problem. You can treat this with a fungicide or by applying neem oil.
Pruning a Japanese willow bush is an important part of caring for the plant. It is best to prune the shrub when it is small to control its size.

The best time to prune a Japanese willow is late winter or early spring.
To start pruning your Japanese willow, remove approximately 30 percent of its height. Then, prune the new growth back to a height of about a foot or less. This process will help the willow grow more efficiently.

To get the best result from your willow bush, begin by pruning its top growth and cutting back the older branches. This will encourage new growth and reduce the risk of disease.

While pruning a willow tree is not necessary every day, you should be very careful not to cut the trunk. This can result in sap oozing out of the tree. In addition, it can be difficult to identify the central leader. To make it easier to determine the central leader, trim back the largest branch of the trunk.
