The oakleaf hydrangea (Hydrangea quercifolia)is a deciduous shrub native to the southwestern United States. The hairy leaves are 4- to 6-inches long and shaped like oak leaves, hence the name oakleaf hydrangea. In the fall, the leaves turn crimson and bronze. The oakleaf hydrangea can reach a height of 8 feet and prefers rich and moist soil. Starting in the spring, the oakleaf hydrangea begins producing creamy white flowers that eventually fade to pink and green.
Place the 1-gallon pot in the area where the oakleaf hydrangea will remain. Oakleaf hydrangea's prefer partial to full shade, although they can withstand some sunlight, so make sure the pot is not situated in full sun the entire day. Avoid hot and dry planting sites.
Lay a one-inch layer of broken pot pieces on the bottom of the 1-gallon pot. This will prevent the water from gushing out after a good watering and ensure a slow and gradual release.
Fill the pot up three-quarters of the way with one-part compost and one-part potting soil. With a garden trowel, turn over the nutrient-laden mixture to fully incorporate both into the pot. Test the soil to ensure you have the ideal pH between 5.5 and 6.5.
Dig a hole large enough to accommodate the root ball of the hydrangea. Remove the oakleaf hydrangea from its original pot and gently pull apart the root ball to allow each root to begin soaking up needed nutrients and water.
Insert the hydrangea into the dug hole and fill up the remaining sides with soil. Press firmly down around the plant to ensure a snug fit into the soil.
Lay a 3- to 4-inch layer of mulch over the plant to ensure a moist soil, the preferred soil type of the oakleaf hydrangea. Thoroughly water the hydrangea until the roots have become fully established.
