Tips for Growing Heat-Tolerant Hydrangeas

Even heat-tolerant hydrangeas need proper care to thrive in hot climates. Here are some tips to help your hydrangeas flourish:

  1. Choose the Right Location: Plant your hydrangeas where they’ll receive morning sun and afternoon shade. This helps protect them from the most intense heat of the day.
  2. Water Regularly: Hydrangeas need consistent moisture, especially in hot weather. Water deeply and regularly, ensuring the soil stays evenly moist but not waterlogged.
  3. Mulch Generously: Apply a thick layer of mulch around the base of your hydrangeas to help retain soil moisture and regulate temperature. Mulch also helps to suppress weeds.
  4. Feed Wisely: Use a balanced, slow-release fertilizer in the spring to support healthy growth and blooming. Avoid over-fertilizing, as this can lead to lush foliage at the expense of flowers.
  5. Prune Properly: Pruning needs vary by hydrangea type. For example, Panicle and Smooth Hydrangeas bloom on new wood and can be pruned in late winter or early spring. Oakleaf and Bigleaf Hydrangeas bloom on old wood, so prune them after flowering to avoid cutting off next year’s buds.
  6. Monitor for Pests and Diseases: Keep an eye out for common hydrangea pests like aphids and spider mites, as well as diseases like powdery mildew. Treat any issues promptly to keep your plants healthy.
