Climbing hydrangea ((Hydrangea anomala subsp.petiolaris) is a deciduous vine with attractive foliage and white blooms that appear in mid-summer. This vine has aerial rootlets that allow it to easily attach to most surfaces. In winter the bark turns red, creating an interesting focal point in the garden after autumn's color is long gone. Climbing hydrangea is hardy in USDA zones four to seven and can grow up to 80 feet tall.
Remove all weeds, grass and large rocks from the chosen planting site. Use a garden fork to loosen the soil to a depth of 5 inches. Add 3 to 4 inches of organic compost and mix well with the loosened soil.
Dig a hole that is the same width and depth as the container that the plant is growing in. Gently squeeze the sides of the container until the root ball slips free. Use your fingers to loosen any roots that are compacted.
Lower the hydrangea into the hole and replace the soil. Pat down firmly to eliminate air pockets around the roots. Water until the soil is very moist but not enough to result in puddles.
Cover the soil around the climbing hydrangea with a 2-inch layer of organic mulch to help retain moisture and control weed growth.
Water regularly during the growing season whenever the top inch of soil does not stick to your finger.
