About this plant
This is a vigorous hydrangea that clings to shady walls. There are heart-shaped leaves, shiny as polished shoes in spring, and then, a little later, flat heads of creamy-white flowers in June. There is brief yellow autumn colour and pleasure in seeing the long-reaching brown shoots seeking to extend their territory. It is very useful to clad difficult sites where few ornamental plants will grow and it makes a pretty good job of shinning up old trees.

Water to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Summer
Summer - early · Outdoors
Apply slow release fertiliser
Apply a slow release fertiliser which is spread around the root area of the plants soon after they have come into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Summer · Planting
Prune after flowering
Remove any dead or damaged branches, or any growth that looks very untidy. Trim the plant back if necessary to keep it within bounds.
