According to folklore, blue hydrangea flowers symbolize remorse and gratitude, while pink hydrangea flowers signal romance.
Recommended Hydrangea Varieties
- Macrophylla (H. macrophylla) - Smooth (H. arborescens) - Panicle (H. paniculata) - Oakleaf (H. quercifolia) - Climbing (H. anomala)
Water plants deeply three times a week throughout the growing season for the first year or two after planting to encourage root growth.
Prune those that bloom on new growth in late winter or early spring before new growth starts. Those that bloom on old growth should be pruned after blooming, which gives them time to develop “old” wood before the next season to support plenty of buds.
Potential Pests and Diseases
Although hydrangeas generally are not subject to serious diseases or pest problems, Japanese beetles, aphids, and spider mites can affect the plants.
Preparing Hydrangeas for Winter
Some experts advise making a cage to cover the entire plant. Continue watering until the ground freezes and dress the soil with compost to provide food for the winter.
