About this plant
This climbing hydrangea has quite small heads of creamy white flowers that are held in rounded clusters and which carry a sweet fragrance, some say musky others honey. The flowers are borne in May. The hydrangea is also grown for its attractive foliage - the leaves are long and shiny green. It needs the protection of a warm wall or it can be grown into a tree. This is quite slow growing and is not reliably hardy across the country, so it may need some protection during winter.

Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming 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.

Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
