In the formal style of pruning, one focuses on pruning for an outward shape of the tree rather than inner openness. This style also helps to encourage additional blooming, as it forces the tree to grow more new wood on which the newer blossoms appear.

Garden Shears
To prune a crepe myrtle tree use sharp and clean pruning tools.
The bypass pruning shears will give good effective results, but use a saw for branches which are more than one inch in diameter. So, clean your garden tools with a solution of 1 part of bleach and 4 parts of water. Then start at the bottom and trim out all the suckers, that are growing around the base of the tree.
