Answer: I think your shrub will benefit from a little pruning to encourage new growth. Prune all of the stems down by one-third to promote healthy new growth. Endless Summer owes its success to its ability to bloom on new wood as well as old. Many Hydrangeas are perfectly hardy in the north, but late frosts freeze out the buds and they never come into bloom. By repeating over such a long period, Endless Summer avoids that problem, giving you color no matter how icy your spring turned out to be.
These flowering shrubs thrive in part-shade and prefer a moist, woodsy soil enriched with peat moss and leaf mold. For best success, water them well throughout the growing season.
