Climbing hydrangeas will grow in full sun or shade. Plant it in rich, moisture-retentive but well-draining soil. It climbs with the aid of rootlike holdfasts, which cling to almost any surface. Climbing Hydrangea's growth habit is unusual for a vine, because plants have lateral branches that will grow out as much as 3 ft from the supporting structure, giving a rich, deep texture that is quite unlike that of other vines, which more typically twine up a narrow support. It is slow growing for the first 2-3 years after planting but will really take off once the roots are well established. There are no major insect or disease problems associated with climbing hydrangeas. |
