How Often to Water Crepe Myrtle After Planting

Crepe myrtle trees (Lagerstroemia spp.) are popular ornamental trees in many landscapes due to their beautiful and showy summer blooms. However, achieving robust growth and healthy blooms requires proper care, including regular watering after planting. In this article, we’ll discuss how often to water crepe myrtle after planting to help ensure the success of your new tree.

Watering Frequency

The frequency of watering crepe myrtle after planting depends on several factors, including the soil, weather conditions, and the size of the tree. For the first few weeks after planting, it is important to keep the soil consistently moist, but not waterlogged. Aim to water the tree deeply once or twice a week, depending on the weather and soil conditions.

During periods of prolonged drought or high temperatures, crepe myrtle may need more frequent watering to prevent stress and wilting. In general, the tree should receive at least one inch of water per week, either from rainfall or supplemental watering.

Watering Techniques

The most effective way to water crepe myrtle after planting is by using a soaker hose or drip irrigation system. These methods deliver water directly to the root zone, minimizing runoff and allowing the tree to absorb water more efficiently.

When using a soaker hose, place it around the base of the tree, making sure to cover the entire root zone. Keep the water on for several hours, enough to soak the soil to a depth of 6-8 inches. If using a drip irrigation system, adjust the emitters to ensure even coverage of the root zone.

Avoid overhead watering methods, such as sprinklers, as they can waste water by evaporation, and may also promote fungal diseases in humid climates.

Watering Tips

Here are some additional tips to help you water crepe myrtle effectively:

Water early in the morning or late in the day to minimize water loss and evaporation.

Avoid getting water on the leaves and blooms of the tree, as this can promote fungal diseases.

Apply mulch around the base of the tree to help retain moisture in the soil, but keep the mulch away from the trunk to prevent rot.

Check the soil moisture regularly, especially during hot and dry periods, and adjust the watering frequency as needed.

Don’t forget to water the tree during its first winter, as winter drought can also stress the tree.

Conclusion

Crepe myrtle trees are a beautiful addition to any landscape, but they require proper care and watering to ensure healthy growth and abundant blooms. By following the tips and techniques outlined above, you can help your new tree establish a strong root system and thrive for years to come.
