  1. Increase irrigation

    Water your hydrangea plant more often to compensate for the summer heat that causes wilting. Give your plant at least 10 gallons of water every week using a slow, steady drip system. Increase water application if wilting continues.

  2. Treat diseased leaves

    Inspect the hydrangea leaves for any pest infestation. Powder on the leaves is a sign of mildew, and you need to water in the morning and evening to decrease humidity. Remove infected leaves, and spray the plant with 4 teaspoons of baking soda and 2 tablespoons of horticultural oil mixed in a gallon of water.

  3. Treat infested plants

    Treat the hydrangea for an aphid infestation if the leaves have small, yellowish insects on them. Wash the leaves, and spray them with a mixture containing 2 ounces of dishwashing soap and 1 gallon of water.

  4. Treat the soil

    If your plant continues to wilt and has yellowing leaves, treat the soil with an iron supplement. Add 2/3 ounce of chileated iron to 10 gallons of water. Apply the iron supplement only to the roots of the plant.
