Care of Annabelle Hydrangeas


Annabelle hydrangeas (Hydrangea arborescens) are deciduous shrubs that grow best in USDA zones 4 through 9. An Annabelle hydrangea boasts beautiful white flowers and reaches a height of 4 feet with a width of 5 feet. These shrubs grow best in neutral to acidic soil and are relatively easy to care for if you follow a few basic rules.

Step 1

Plant your Annabelle hydrangea in a spot that gets either full sun or partial shade. Too much shade will stunt the growth of the flowers. Full sun equals six hours or more sunlight per day. Partial shade means your Annabelle hydrangea is still able to get three hours or more of direct sunlight each day.

Step 2

Water your Annabelle hydrangea until the soil is moist. Don't let it get soggy, though. Backyard Gardener recommends 1 inch of water per week.

Step 3

Fertilize your Annabelle hydrangeas. Kennedy's Country Gardens recommends using a 5-10-5 granular fertilizer once each spring.

Step 4

Prune your Annabelle hydrangeas only if the flowers are becoming too heavy for the plant. It is best to do this in the middle of the spring, after all of your flowers have bloomed.

Step 5

Keep an eye out for pests. Snails and slugs are your hydrangea's biggest threat. If you notice any adults, set out a few beer cans that are half full with beer. The snails and slugs will climb in and drown.

Tips and Warnings

  • If you have a large infestation of snails or slugs you will have to use a chemical pesticide.
