Annabelle Hydrangea Planting Guidelines

Hydrangea is a deciduous shrub that is native to southern New England, the Midwest and the southern U.S. The Annabelle hydrangea blooms in very large, white pom-pom like flowers, in late June. The flowers can become so large and heavy that they will be weighted down by a heavy rain and droop to the ground. When choosing your planting location keep in mind that the Annabelle hydrangea will grow 3 to 5 feet tall and is generally wider than it is tall. Plant your hydrangea in early summer or late fall.

Light Requirements

Choosing a planting location will depend upon where you live. If you live in the northern U.S., you can plant your Annabelle hydrangea where it will receive all-day sun. Ideally, you will want to give the Annabelle hydrangea dappled sunlight. It may be tempting to plant the Annabelle under a large tree, but it is not advisable. Hydrangea need moisture and can't compete with the roots of large trees. If you can't find a spot with dappled sunlight plant your Annabelle hydrangea where it will receive afternoon shade. This is especially important if you live in an area with hot summer temperatures.

Soil Requirements

The texture of the soil in which the Annabelle is planted will bear heavily upon its success in your garden. Well-drained soil is a must. It's always a good idea to amend the soil prior to planting by adding amendments such as sphagnum peat moss, pine-bark mulch and aged compost. If you have a soil ph meter, aim for a slightly acidic to neutral soil pH.

How to Plant

Dig the planting hole so that it is bowl-shaped, and three times the width of the pot in which it currently sits. The depth of the planting hole should be deep enough to allow the crown of the plant to sit about one inch below the surface of the soil. Gently loosen the rootball and spread the roots out. Place the Annabelle hydrangea into the planting hole and fan out the roots. Make sure that the bottom of the plant is sitting firmly on the bottom of the hole. Backfill the hole with soil, firming it as you go to remove air pockets. Add a 3-inch layer of aged mulch to the soil around the base of the plant and water well.
