When pruning trees, be sure to use the proper tools, and be sure that they are all in good condition.
Hand pruners are useful for branches less than one-half an inch thick.
For limbs up to 30 feet high, use pole pruners. Hand saws are the most common tool for homeowner pruning, but take extreme care when pruning with a power chain saw. Avoid power tools not specifically designed for pruning. Consider professional help for pruning larger trees. To remove a large branch, make an undercut on the branch about one foot from the trunk.
