1. Soil

 Soil

 

Luckily, Crepe Myrtle varieties are not very demanding for a particular soil pH, but they like slightly acidic or neutral soil over alkaline. Once planted, you should use soil to pack the roots. To ensure healthy growth and proper crepe myrtle bush care, start with wet soil and regularly water across the first year in the growing season. It helps avoid air pockets and does not dry the roots.

 

In all situations, the soil must be well-draining because the plant cannot tolerate standing water as it can result in root rotting. In addition, you must not grow the crepe myrtle in very rich soil. It can result in more foliage than desired.

 

2. How much sun do crepe myrtles need?

An imperative aspect of understanding how to care for crepe myrtle trees is understanding the plant’s sun requirements. The plant thrives in full sun and demands at least six hours of full sun. If the plant does not receive ample sunlight, it becomes droopy, and leaves begin to fall.

 

Hence, you must plant them in a spot where it receives sunlight for most of the day. You will fail to offer the necessary crepe myrtle bush care if you grow the tree in shaded areas, resulting in stunted growth.

 

3. Location

Pick a location with generous space for the tree to grow to its intended height sans restriction. When planting the crepe myrtle, ensure there is ample horizontal space to allow the plant to expand, but be thorough with your chosen variety’s maximum height, as the overhanging elements or porch ceilings might curtail their growth.

 

Regardless, for proper crepe myrtle tree care, it is recommended to have an unobstructed space like a fence line or driveway to plant the trees as it receives necessary sunlight without having to compete for space.

 

4. Water

Water

 

Unlike most trees, crepe myrtles demand consistent watering till they establish their roots. But that does not mean you overwater the plants. Even though it has medium watering requirements, it can be reasonably drought-resistant, provided it receives water at least once a week.

 

If you live in a geography wherein rains are infrequent, you must ensure that the surrounding soil is perennially moist. How to care for crape myrtle depends on the trunk’s diameter. It indicates how much water the tree demands. If it is large, the watering requirement will be high. The ideal situation for care is eliminating overwatering and planting trees in well-drained soil.

 

5. Fertilizer

Ensuring the plant receives the desired nutrition is vital for the crepe myrtle tree care. Ideally, you must fertilize the plant lightly or avoid it altogether. These supplemental fertilizers boost foliage growth but inhibit bloom production. So, if necessary to use a fertilizer, opt for a slow-release alternative with high nitrogen content.

 

When the leaves appear first, you can use this fertilizer for proper crepe myrtle bush care. An acid mulch comprising oak leaves or pine bark can also help promote growth. To understand whether the feed is suitable for your plant, check the label and read through its NPK formulation.

 

However, before fertilization, perform a soil assessment test to assess whether your soil is deficient or if there is any other issue. How to take care of crepe myrtle once the growing season ceases? Following the growing season, crepe myrtles should be fertilized only once a year, typically in the spring before the emergence of the new growth.

As you prepare for the colder months, you can discontinue the fertilizer to toughen the plant for dormancy.

 

6. Temperature and humidity

As per the USDA zone map, crepe myrtle grows in the hardiness zones six through nine, but sadly, if you want to execute proper care, planting north of seven is not recommended. Only the well-guarded underground or mulched roots can be hardy to thrive in colder climates.

 

However, the exposed branches may die if the temperature drops below -5-degree Fahrenheit. In case of dead branches, how to care for crepe myrtle? You can prune all the branches to the soil level to guard the roots. The plant blooms on the new wood, implying new growth every spring. Once established, the plant is drought and heat-tolerant.

Most people find pruning the crepe myrtle a chore. However, it is pivotal for multiple reasons. Hence, for best results your crepe myrtle tree care, must include pruning the crepe myrtle in early spring or winter.

 

Crepe myrtles have a fast growth rate. Pruning can further help foster bloom production and beautify the plant by elevating seasonal interest, exfoliating the bark, and establishing the best form and size by eliminating errant branches and suckers.

 

In the case of giant trees and shrubs, you can chop off twiggy growth, remove basal suckers, cross branches, and those growing towards the plant’s center. Be careful while pruning, and progress slowly, removing the side branches up to four to five feet, thereby revealing the beautiful bark of the trunks.

 

Since crepe myrtles blossom on the new wood, proper crepe myrtle tree care demands pruning during early spring or winter. It motivates attractive blooming. Please remember if you wish to establish the plant in the tree form, you must prune all but one trunk using loppers or hand pruners. It helps determine a clear leader.

 

However, deciding to grow as a tree can be added to the continuous chore of tidying the suckers. You will have to perform regular structural pruning till there is an established leader.

Step 3 – Lastly, wrap small and young Crepe trees with burlap and add an insulating filter like straw or leaves to receive added protection. For dwarf plants, you can use bush jackets. These are reusable insulating covers enveloping the plant. During the spring, get rid of all the extra wraps and mulch.
