Hydrangeas That Are Evergreen: A Guide to Growing and Caring for Them
Hydrangeas are beloved for their showy, abundant blooms that adorn gardens across the world. But did you know that there are varieties of hydrangeas that remain evergreen throughout the year? These beautiful plants provide interest and structure in the garden even during the colder months. In this guide, we will explore the world of evergreen hydrangeas and provide tips on how to grow and care for them.
What are Evergreen Hydrangeas?
Evergreen hydrangeas are a type of hydrangea that keep their leaves throughout the year. Unlike deciduous hydrangeas, which lose their leaves in the fall, evergreen hydrangeas retain their foliage, providing structure and color to the garden all year long. There are several species of evergreen hydrangeas, including Hydrangea seemannii and Hydrangea integrifolia, both of which are native to Asia.
Growing Evergreen Hydrangeas
When it comes to growing evergreen hydrangeas, the most important factor is location. These plants prefer partial shade or filtered sunlight, as direct sunlight can scorch their leaves. Additionally, they prefer moist, well-drained soil that is rich in organic matter. It's also important to avoid planting evergreen hydrangeas in areas with strong winds or extreme temperatures, as they can be sensitive to both.
When planting evergreen hydrangeas, be sure to dig a hole that is twice the size of the plant's root ball. Mix in some compost or peat moss to improve the soil's moisture retention and nutrient levels. After planting, water the plant well and apply a layer of mulch around the base to help retain moisture.
Caring for Evergreen Hydrangeas
Once established, evergreen hydrangeas require relatively little maintenance. Water them regularly during dry spells, but be careful not to overwater, as this can lead to root rot. Fertilize the plants once a year in the spring using a balanced, slow-release fertilizer. Pruning should be done in the late summer or early fall to shape the plant and remove any dead or diseased branches.
It's also important to monitor evergreen hydrangeas for pests and diseases. Common issues include aphids, spider mites, and powdery mildew. If you notice any signs of infestation or disease, act quickly to prevent further damage. Most issues can be treated with insecticidal soap or fungicide, depending on the problem.
Choosing the Right Evergreen Hydrangea
When selecting an evergreen hydrangea for your garden, consider the plant's size, bloom time, and overall appearance. Some varieties, such as Hydrangea seemannii, can grow up to 30 feet tall, while others, like Hydrangea integrifolia, are more compact and suitable for smaller gardens. Additionally, some evergreen hydrangeas bloom in the spring, while others bloom later in the summer or fall.
Other factors to consider include leaf size and shape, as well as color. Some evergreen hydrangeas have large, glossy leaves, while others have smaller, more delicate foliage. The color of the leaves can also vary from deep green to bronze or burgundy. Ultimately, the right evergreen hydrangea for you will depend on your personal preferences and the conditions in your garden.
Evergreen hydrangeas are a wonderful addition to any garden, providing year-round interest and beauty. By selecting the right location, providing proper care, and monitoring for pests and diseases, you can enjoy these stunning plants for years to come.
