Tips For Promoting Healthy Growth

Crepe myrtles are popular ornamental trees known for their beautifully bloomed flowers and a wide range of sizes, from tall trees to compact shrubs. They are easy to grow and care for but need some maintenance to promote healthy growth.

Here are some tips on how to keep your crepe myrtles healthy and vibrant.

Pruning Techniques And When To Prune

Proper pruning is crucial for the healthy growth of crepe myrtles.

  • prune for shape: prune your crepe myrtle to shape it while it is still dormant in early spring. You can also do some light pruning during the growing season if needed.
  • deadheading: deadheading helps encourage blooming by removing expired flower heads. It also prevents the formation of seedpods that can drain the plant’s energy.

Fertilizer Application And Schedule

Crepe myrtles do not require high-nitrogen fertilizers. Instead, they thrive on moderate to low-nitrogen fertilizers that contain phosphorus and potassium.

  • when to fertilize: apply fertilizer after the tree blooms and before the fall season starts. In most cases, one or two applications per year should suffice.
  • fertilizer choice: choose fertilizers that are specifically for flowering trees and shrubs. Avoid using fast-release fertilizers that may damage the roots.
  • proper application: apply the fertilizer in a slow, steady stream to the drip line of the tree. Water the tree thoroughly after fertilizing to allow the nutrients to penetrate the soil.

Pest Management Practices

Like any other plants, crepe myrtles can become vulnerable to pests and diseases.

  • inspect regularly: regularly inspect your crepe myrtle for signs of pests and diseases. Some common pests include aphids, spider mites, and scale insects.
  • natural remedies: use natural remedies such as insecticidal soaps or neem oil instead of chemical pesticides. They are safer for the environment and do not harm beneficial insects.
  • prune out damage: prune out damaged or infected parts of the tree to stop the spread of disease. Burn or dispose of the infected plant parts immediately.
