The Care of PeeGee Hydrangeas

Overview

The peegee hydrangea (Hydrangea paniculata) is also known as the grandiflora. The deciduous shrub grows 25 feet in height with a 16-foot spread. Long, white flower panicles that often reach 18 inches in length are produced in the late summer. As the flowers age, they turn a very light shade of pink. The flowers are all sterile. The peegee hydrangea is a cultivar from the 1860s, according to the Missouri Botanical Garden. The shrub is easy to maintain with no serious insect or disease threats. It is exceptionally cold-hardy and easily grown in the north United States as well as the hot, humid regions of the South.

Step 1

Plant in well-drained soil that is rich in organic matter. Mix in peat moss, aged manure, leaf debris or sawdust at a ratio of 50 percent organic matter with 50 percent garden soil. Choose a location that offers full to partial sunlight.

Step 2

Apply 3 to 4 inches of mulch such as peat moss, recycled plastic mulch or bark chips around the base of the peegee hydrangea. The mulch will help keep the soil moist in the height of the hot summer.

Step 3

Water the peegee hydrangea regularly to keep the soil moist but not water-logged. The shrub does not like standing water around its roots.

Step 4

Prune in the late winter after the flower production has ceased. Cut the branches back to the first few buds on each stem. The shrub should be pruned to five to 10 branches.

Step 5

Fertilize the hydrangea in early spring using a 10-10-10 general purpose fertilizer. Apply according to the directions on the label. Water the fertilizer into the ground thoroughly.
