Factors To Consider

Crape myrtles are sun-loving plants and enjoy at least 6 hours of sunlight per day. However, there are several factors to consider before planting them in full sun.

  • Climate: crape myrtles are more adaptable to full sun in humid climates than in arid or temperate climates.

Alternatives To Full Sun For Crape Myrtles

If full sun is not an option, other suitable growing conditions for crape myrtles include:

  • Morning sun: morning sunlight is less intense than afternoon sun, making it an excellent alternative for crape myrtles.
  • Shaded pathways: crape myrtles can grow successfully along paths or areas that are partially shaded by nearby buildings and trees.

  • Cercospora leaf spot: small, circular purple or brown spots on leaves. Avoid watering over the foliage and remove fallen leaves to prevent and control.
