Hydrangeas were my mother’s favorite flower and landscape shrub and she was a strong influence for me to include hydrangeas in my garden. I now have 55 separate plants on a pie-shaped .73 acre lot. Most I have purchased outright to get different varieties, and about 12 or so are propagated, something I learned how to do from Master Gardener workshops.
A large factor on how hydrangeas will perform is Mother Nature. A dip in temperature in the spring — a late frost will devastate the summer performance of many hydrangeas. Knowing the type of hydrangeas you have, where it will thrive, its sun requirements, and ultimately how to prune correctly are essential for growing profuse blooms.
In Delaware, Zone 7b, we had a very wet, soggy spring and no late frosts! The result: a blooming bonanza for Hydrangeas! July will bring the paniculatas such as Limelight, Little Limelight and Little firelight.
