A hydrangea care guide is typically an instruction booklet or leaflet that explains how to plant, water, grow, prune and maintain a hydrangea. These guides are designed to help grow healthy hydrangeas.
While there are many different kinds of hydrangeas, general hydrangea care guides instruct readers to plant the hydrangea in a spot that receives an equal amount of sun and shade throughout the day. The soil also needs to be moist with good drainage. Hydrangeas should be planted at least three inches apart, and they do not need to be placed in very deep holes. Once a hydrangea is planted, spread compost around the plant every year to ensure that it continues to grow and bloom.
