How to Plant a Hydrangea Shrub


Hydrangeas are flowering plants that can be grown in USDA zones 4 through 9. According to the U.S. National Arboretum, there are about 23 species of hydrangeas. Most hydrangeas are considered shrubs that reach a height between 3 and 9 feet. A few are considered small trees. You can recognize a hydrangea by its flowers because they are said to resemble the head of a mop. The flower colors are either blue, red, pink, white or purple. Planting hydrangeas in your garden can give it that extra color you are looking for.

Step 1

Choose a location in your garden that gets a little bit of shade, but has soil that drains well. Hydrangeas can tolerate full sun, but partial shade is best. If the soil does not drain well, mix pine bark mulch in it.

Step 2

Make sure the location you choose will allow a space of 4 feet by 4 feet for each hydrangea. This will allow the hydrangea to reach its full potential.

Step 3

Dig a hole that is large enough to fit the hydrangea rootball, and no larger. Hydrangeas should not be planted deep in the soil.

Step 4

Set your hydrangea rootball in the soil and cover it with some of the soil you dug up. Pat the top of the soil to release any air pockets that may have formed around the rootball.

Step 5

Water the hydrangea and keep the soil moist. Do not allow the soil to become soggy as hydrangeas are very prone to root rot.

Step 6

Fertilize your hydrangeas. The University of Rhode Island recommends a 5-10-10 fertilizer. Do this once in the spring and once during the summer.

Tips and Warnings

  • Growing your hydrangeas in an area of your garden that is fully shaded will result in less flowering.
