Difficulty: Moderately Easy
Step1
Give your hydrangeas morning exposure to the sun. Allow for shade in the afternoon or keep them in the sun all day as long as you water them frequently.
Step2
Fertilize your hydrangeas once or twice a year. Apply fertilizer only once in the middle of summer if you live in cooler climates. Fertilize once at the beginning of summer and once toward the end if your climate is hot. For best results, use a slow-releasing fertilizer.
Step3
Prune your hydrangeas in the spring. Cut back old branches and stems, but avoid the plant's new growth. Clip half of the stems of your hydrangea in the summer.
Step4
Protect your hydrangeas in inclement weather. Cover them when the temperature is going to drop below 25 degrees F.
