With the summer heat upon us, be sure to keep your hydrangeas well hydrated. Some wilting during the hottest part of the day is normal, but if your plants are still wilted in the morning, that’s a clear sign they need water.

A deep watering can help your hydrangeas recover and continue to thrive through the heat. Keep an eye on your plants, and remember that consistent moisture is especially important during periods of extreme temperatures.

Stay cool, and happy gardening!
