How to Grow an Oak Leaf Hydrangea

Overview

Oakleaf hydrangea (Hydrangea quercifolia) is a large deciduous shrub with leaves resembling oak leaves and large, white flower clusters. Hardy in zones 5 to 9, the leaves turn color in the fall if planted in sunny areas. This shrub grows up to 5 feet high and just as wide and tolerates a bit of shade, especially in the afternoon hours. However, it may not do well in clay soils.

Planting and Care

Step 1

Plant container-grown plants in the spring, in well-drained soil. Dig a hole twice the diameter of the root ball, but only as deep as it was in the pot. Add a bit of compost or manure to the soil, mix well, and place the plant in the hole. Cover with soil, compact and water generously.

Step 2

Once established, oakleaf hydrangeas need not be watered as often, since they don't like "wet feet". Overwatering will cause the roots to rot.

Step 3

Hydrangeas can be fertilized once or twice during the summer. Chemical fertilizer in a 10-10-10 formula will work well, or you can add compost or manure to the soil around the base of the bush

Step 4

Oakleaf hydrangeas should have a thin layer of mulch around the base of the shrub throughout the blooming season.

Step 5

Regarding pruning; this variety of hydrangea doesn't require it, unless there are fallen or broken branches that need to be removed. Otherwise, just sit back and enjoy the show.
