Angel's Blush Hydrangea - very slow to grow - Knowledgebase Question

Seattle, WA
Question by minda
December 22, 2005
I bought 3 Angel's Blush Hydrangeas in 2001, prepared a new bed with lots of compost and have had them on a sprinkler system every summer but they have not grown more than 1 foot. They are on the north side of a 6' lattice fence but they get at least 5 hrs/day of sunlight in the summer months. They aren't flowering much and the few flowers are very small. What should I do to get them to grow and flower better?

Thank you.

Angel's Blush Hydrangea is typically a vigorously growing shrub that thrives in either shade or part sun. It can take a full season for the roots to establish themselves, but once that happens, they should really grow well. The site sounds fine for your shrubs, as does the regular water they receive, so I'm at a loss as to why they aren't growing well for you. You didn't mention whether or not you've pruned your hydrangeas. Annual pruning will encourage new growth and will help your plants produce new flowering shoots. Next spring, just as the buds begin to swell on the branches, cut your shrubs back by several inches to encourage new flowering stems. The shock of pruning should make them wake up and grow. Best wishes with your garden!
