The Annabelle Hydrangea is easy to grow and dependable. It is perhaps the most popular old-fashioned shrub grown in American gardens today.
The Annabelle produces white flowers up to 12 inches across and blooms every year even after severe pruning or intensely cold winters. The huge, white blooms appear in early to late summer, and the Annabelle will grow to be approximately 3 to 4 feet tall.
Soil should be consistently moist but well draining for the Annabelle to thrive. This particular hydrangea can grow in full sun if it is watered well, but will bloom more freely in partial shade. As far as fertilizing, an all purpose fertilizer should be applied once prior to the leaves emerging and again once the Annabelle has flowered. Annabelle hydrangea is great to use in borders, hedges, foundation, or accent plantings.
How to plant Annabelle Hydrangea
Dig your planting hole to twice the diameter of the hydrangea root ball. You should dig the hole so that once planted, the hydrangea will be at the same level in the ground as it was in its container.
Before you place your hydrangea into its hole, you should loosen the soil around the outside of the root ball. This will help the roots to spread more easily once it is planted.
Place your hydrangea shrubs into the hole. Backfill the hole with soil and pack it down firmly. Water well to help get rid of air pockets in the soil.
Add a layer of mulch to your newly planted hydrangea. This will help the soil to conserve moisture.
