How to prune a mulberry tree
Disinfect your clippers before trimming.
To make sure that your mulberry tree stays healthy and disease free, be sure to clean your clippers before using them. You can do this with a household disinfectant product, such as lysol or bleach.
You can also rub isopropyl alcohol on the clippers to disinfect them. Cleaning your clippers is especially important if you have more than one mulberry tree.
