How to Train a Crepe Myrtle Into a Tree
Crepe myrtles are popular flowering shrubs that can be trained into beautiful, multi-stemmed trees. By proper pruning and training techniques, you can transform your crepe myrtle into an elegant tree form, adding height and structure to your garden. Here’s a step-by-step guide on how to train a crepe myrtle into a tree.
1. Select the right variety: Choose a crepe myrtle variety that is suitable for tree form growth. Look for varieties that naturally have a strong central leader and upright growth habit. Examples of suitable varieties include Natchez, Muskogee, and Tuscarora.
2. Choose a location: Crepe myrtles thrive in full sun, so select a spot in your garden that receives at least six hours of direct sunlight per day. Ensure that the soil is well-draining to prevent waterlogging, as crepe myrtles prefer slightly acidic soil.
3. Prune for a single trunk: In the first year, prune your crepe myrtle to encourage a single trunk. Select the strongest, most upright stem and remove all other stems at ground level. This will allow the selected stem to become the main trunk.
4. Train the branches: As your crepe myrtle grows, select 3-5 strong lateral branches to form the main framework of the tree. These branches should be evenly spaced around the trunk and have a wide angle of attachment. Remove any other branches that compete with the framework branches.
5. Prune for structure: Once your crepe myrtle has reached the desired height, it’s time to prune for structure. Remove any suckers or small branches that sprout from the base of the tree, as well as any weak, crossing, or rubbing branches. This will encourage a well-balanced and aesthetically pleasing tree form.
6. Maintain annual pruning: Crepe myrtles benefit from annual pruning during their dormant season, which is typically in late winter or early spring. Prune back any dead or damaged wood, thin out crowded branches, and shape the tree to maintain its desired form.
7. Provide adequate care: Proper care is essential for the health and longevity of your crepe myrtle tree. Water regularly, especially during dry spells, and mulch around the base of the tree to retain moisture and suppress weeds. Fertilize in early spring with a slow-release, balanced fertilizer to promote healthy growth and abundant blooms.
FAQs:
1. When is the best time to train a crepe myrtle into a tree?
The best time to train a crepe myrtle into a tree is during its dormant season, which is typically in late winter or early spring.
2. Can any crepe myrtle variety be trained into a tree?
Not all crepe myrtle varieties are suitable for tree form growth. Look for varieties that naturally have a strong central leader and upright growth habit.
3. How long does it take for a crepe myrtle to develop into a tree?
The time it takes for a crepe myrtle to develop into a tree depends on various factors such as the variety, growing conditions, and pruning techniques. On average, it may take 2-4 years to establish a tree-like form.
4. Should I remove all the branches except the selected trunk in the first year?
Yes, in the first year, it’s important to prune away all other stems at ground level, except for the strongest, most upright stem that will become the main trunk.
5. Is it necessary to prune my crepe myrtle every year?
Annual pruning is recommended to maintain the health and shape of your crepe myrtle tree. Prune during the dormant season to remove dead wood, thin out crowded branches, and shape the tree.
6. Can I train a mature crepe myrtle into a tree form?
While it is possible to train a mature crepe myrtle into a tree form, it can be more challenging as the shrub may have already developed multiple trunks. It is best to start training when the plant is young.
7. How tall can a crepe myrtle tree grow?
Crepe myrtle trees can reach heights ranging from 10 to 30 feet, depending on the variety and growing conditions. Regular pruning and training will help maintain the desired height and shape of your tree.
