Help, my hydrangea is wilting

Summer heat causes flowers to wither

Especially at high summer temperatures or in a sunny location, the hydrangea flower balls often hang limp. This is a completely natural process that the hydrangea uses to protect itself from excessive evaporation. If the temperatures drop, the flowers appear fresh again after a short time.

Do not water immediately

The hydrangea does not tolerate waterlogging well. Therefore, please always check whether the upper centimeters of the substrate feel dry before pouring. On very hot days and sunny locations, it is advisable to shade the hydrangea from time to time. As a rule, the plant recovers quickly when it is no longer exposed to direct sunlight.

Wilting from excessive watering

Waterlogging leads to root rot in hydrangeas. As a result, the roots can no longer absorb enough water to supply the plant with moisture. The flowers droop limply and wither.

Remedy for indoor plants

  • Carefully remove the plant from the pot.
  • If the substrate is spongy and has a foul odor, the hydrangea must be converted.
  • Then carefully remove the substrate and the broken roots.
  • Place in a flower pot with holes covered with potsherds.
  • Use good quality hydrangea or rhododendron soil.
  • In future, only water when the substrate feels dry and immediately pour away excess water.

Natural withering of the flowers

After a while, the hydrangea flowers will fade and the hydrangea will wilt. In order for the hydrangea to set new flowers, you should continuously cut out or break out what has withered during the summer.


  • Grip the stem below the flower with your thumb and index finger.
  • Cut with your thumbnail and break away to one side.

This method is particularly gentle on the plant as the resulting wound closes very quickly.


Do not cut back wilted hydrangeas at first. The plants often recover surprisingly well from “swimming accidents” or short periods of drought.
