Pruning crepe myrtles is a common practice among gardeners and landscapers, but there is often confusion about why people cut them back so far. There are several reasons why this is done, and it is important to understand the objectives of pruning in order to properly care for these beautiful trees.
1. Maintain Natural Form: Crepe myrtles have a naturally graceful and elegant form, with multiple trunks and branches that grow in a vase-like shape. However, over time, some branches may become weak or grow in undesirable directions. Pruning can help maintain the natural form of the tree by selectively removing these unwanted branches, allowing the tree to grow in a balanced and aesthetically pleasing way.
2. Strengthen Branches: By pruning crepe myrtles, you can encourage the growth of strong and sturdy branches. When a tree is pruned back, it stimulates new growth and allows for the development of thicker and more resilient branches. This is especially important for crepe myrtles, as their beautiful flowers can be quite heavy and may cause weak branches to droop or break. Pruning helps create a strong framework that can support the weight of the flowers, preventing damage and ensuring the longevity of the tree.
3. Upright Flowers: Another objective of pruning crepe myrtles is to encourage upright flower growth. When a tree is pruned back, it directs the energy of the plant towards producing new growth and flowers. By selectively removing branches, you can create a more open canopy that allows sunlight to reach all parts of the tree, ensuring that flowers are evenly distributed. This helps prevent the formation of dense clusters of flowers that may droop or become weighed down by rain, resulting in a more visually appealing and healthier tree.
4. Air Circulation: Pruning also plays a crucial role in promoting air circulation within the crepe myrtle canopy. When a tree is densely packed with branches, air movement is restricted, creating a humid and stagnant environment that can be conducive to the growth of fungal diseases. By selectively thinning out branches, you create space for air to flow freely through the tree, reducing the risk of disease and promoting overall tree health.
In my personal experience as a gardener, I have witnessed the positive impact of pruning on crepe myrtles. By following the objectives mentioned above, I have been able to maintain the natural form of the trees, strengthen their branches, and promote upright flower growth. The result is a visually stunning tree that enhances the beauty of the landscape while also ensuring the health and longevity of the plant.
Pruning crepe myrtles back is done to maintain their natural form, strengthen branches, promote upright flowers, and enhance air circulation within the canopy. By understanding these objectives and implementing proper pruning techniques, you can ensure the health and beauty of your crepe myrtle trees for years to come.
