Cultivation

Hydrangeas with this characteristic tend to bloom in early summer, and the flowers die by mid summer. At this point the shrub begins producing the buds that will bloom the following year. Hydrangeas that bloo…

Management
Varieties
Prevention
- When to prune a hydrangea depends on when it sets its flower buds. Other than the modern repeat blooming hydrangeas, like \"Endless Summer\" and \"Lime Light\", most older hydrangeas set the next season's flower buds in either late summer/fall or during the growing season. Hydrangeas that set their buds late in the season are the most likely to have trouble blooming. I…

Culture
- Bigleaf hydrangeas are the variety most susceptible to winter bud injury. If you live in an area with severe winters or your plant is exposed to winter winds, you might need to offer it some winter protection, to protect the flower buds. Tying the branches together and wrapping them with burlap isnt pretty, but it could mean winter survival. Remove the burlap when the buds begin to swell.
Appearance

Causes

You can deadhead the flowers, as soon as they become unattractive and cl...
