Hydrangeas are flowering shrubs that put forth large, showy blooms during the summer. Gardeners who want robust and healthy hydrangeas must focus on providing enough sunshine and water for their plants. It's also important to prune hydrangeas after they blossom so that the shrubs can develop next year’s flower buds. Hydrangeas also require fertilization to thrive; however, they don't require special fertilization. All-purpose Miracle-Gro fertilizer is well suited for hydrangeas.
Things You'll Need
Miracle-Gro fertilizer
Watering can
Mix the Miracle-Gro fertilizer with water according to package instructions for the size of your hydrangea shrubs.
Apply the Miracle-Gro fertilizer every other time you water, about every two to three weeks. Pour it onto the soil under the shrub, being careful not to get any fertilizer on the foliage. Doing so could burn the tender leaves and blossoms. Immediately rinse off any splashes.
Generously water the shrubs immediately after fertilizing to prevent the fertilizer from burning the uppermost roots of the shrub.
Tips & Warnings
If you are concerned about low acidity in your soil, fertilize with Miracle-Gro's Miracid once per week during the growing season. Miracid is a soil acidifier that helps boost soil acidity. Generously water hydrangea shrubs immediately after fertilizing with Miracid to prevent the fertilizer from burning the uppermost roots of the shrubs. Miracid also helps encourage hydrangea blossoms to bloom blue.
