Cultivation
Management
- 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…
Varieties
- The popular mophead hydrangea, also known as bigleaf or florist hydrangea, is sometimes easy to recognize because it is the one whose flower color changes with the soil pH: blue in acid soil, pink in alkaline. There are a few varieties that simply stay white, making it much harder to categorize them from the flowers.
Prevention
- 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.
Uses
- It's probably not surprising that oakleaf hydrangea is easily recognized by its oakleaf-shaped foliage. Since its major attraction is its foliage, loss of bloom is less disappointing than in other varieties. Oakleaf hydrangea also blooms on new season growth and can be pruned in late winter or early spring, while dormant, to remove dead wood. If it has experienced winter dieback…
Culture
- Peegees do not require hard pruning to the ground. New flower buds will be set on new spring growth. Some gentle pruning in late winter or early spring will not only keep the plants from becoming overgrown, it will also encourage more new growth and hopefully more flower buds. You can deadhead the flowers, as soon as they become unattractive and cl...
Appearance
- Tea of Heaven is a small shrub with narrow, pointed leaves and flattened flowerheads. It is sometimes confused with Hydrangea macrophylla because the flowers can look like lacecaps and/or be blue or pink, but it by no means has big leaves. Hydrangea serrata also blooms on new wood and should be pruned in late winter or early spring.
Causes
- The stunning climbing hydrangea is the type you see slowly making its way up a tree or support. It is a vine, not a shrub and requires little to no pruning. Once climbing hydrangeas become established, they can grow quite vigorously and may need occasional summer pruning to stay in bounds.
