Hydrangeas are one of the easiest shrubs to grow, and most cultivars are available in a variety of colors. The most popular varieties are blue and pink, although some can be white, green, or red. While most cultivars bloom for a short time in the spring, the flowers may change color as the plants age. For example, mountain hydrangeas can turn from pink to blue. The flower color of hydrangeas depends on the pH level of the soil.
If you are considering planting a hydrangea in your garden, you should know that they can become tall and spindly. While pruning isn’t necessary, it is important to be aware of the signs of an infestation. These pests can affect the health of the plant and make it grow taller. The most effective way to treat them is with organic insecticides. You can also look for vine weevils on your hydrangea, which can destroy the roots and cause the plant to decline.
Blooming popularity of Hydrangeas
Hydrangeas are a favorite among gardeners and can add a touch of elegance to your garden. Many types have beautiful blooms and are suitable for a variety of locations. They can also form a privacy screen or sprawling ground cover, depending on the variety and its type. Native to Asia and North America, hydrangeas are popular ornamentals and are a wonderful addition to any garden.
Pruning hydrangeas is important in order to promote growth. Cutting off spent flowers in the summer is not necessary. Leave the faded flowerheads on the shrub throughout the winter. A few small branches of the plant are fine to leave for the winter. However, you must prune them correctly so that the new growth can occur. If you want to prevent your hydrangeas from blooming again, you should cut off the buds and allow the shrubs to recover from the frost.
Pruning
Hybrid hydrangeas are tough native plants that flower in the early summer and continue to bloom into the fall. These shrubs can be trained to form a tree, and will produce flowers on the new wood. If you want to prune hydrangeas on their own, you can cut them to a healthy height above their buds. If you don’t want to prune them, you can choose a variety with a large leaf and a wide base.
While pruning is not necessary, hydrangeas will grow taller if they are left unpruned. You can prune them at the base of new wood to encourage flowering. If you have a large hydrangea, cut it back harder when it has new growth. Otherwise, it will continue to grow to be a small tree. If you prune, you should only trim the new wood that grows on the older wood.
