Q.pussy willow
I planted pussy willow tree 3 years ago. It is in a location that receives sun and some shade through the day. I water it weekly during the growing season in my area – March through October. It blooms each year but has grown very little since its planting. What does this tree need for growth and branching out?
Pruning out the shrub can actually help it grow more and produce more catkin filled branches.
Here are some links to help you with care and pruning.
