The snowball-shaped blooms make hydrangeas a popular pick among gardeners. Depending on whether the soil is acidic or alkaline, hydrangeas can show off light blue or pink blossoms that are sure to draw attention to your garden. After a long winter, some preparation needs to be done for the hydrangeas to provide the best growth during the spring and summer months.
Prune the hydrangea plant before it begins to bloom. Remove any brown, dried or dead foliage to make room for new growth. Take care when you prune so you do not to damage the hydrangea.
Water the hydrangea plant often, depending on the frequency of rain in your area. If the winter was a dry winter, water the hydrangea heavily by soaking the soil around the plant thoroughly. Hydrangeas require large amounts water because of their large blooms and thick foliage. The soil around the hydrangea should always be moist to the touch.
Add a water soluble fertilizer when you water. Fertilize the hydrangea once before it begins to bloom in the spring, and once per month following, until blooming has ceased for the winter. You can purchase a water soluble fertilizer at your local garden specialty store, or home improvement store.
Apply mulch around the hydrangeas. The mulch should be approximately 3 to 4 inches deep. The mulch will aid in keeping weed growth down, and will retain moisture so the hydrangea plant will stay well hydrated in the upcoming summer.
