Green Velvet Boxwood is a popular choice for many gardeners and landscapers due to its beautiful evergreen foliage and compact growth habit. However, there are times when this plant can experience issues, such as turning brown. One common cause of browning in Green Velvet Boxwood is winter burn, which occurs when the plant is exposed to drying winter winds.
Winter burn is a result of foliar desiccation, which is the drying out of the leaves. Boxwoods, including the Green Velvet variety, are particularly susceptible to this problem. During the winter months, the combination of cold temperatures and strong winds can quickly dehydrate the leaves, leading to discoloration and browning.
The symptoms of winter burn on Green Velvet Boxwood usually manifest as a reddish-orange to brown discoloration along the midrib or entire interior portion of the leaf. Interestingly, the leaf margins often retain some green color. This distinct pattern of browning can help identify winter burn as the cause of the issue.
To prevent winter burn in Green Velvet Boxwood, there are several measures you can take. Firstly, consider planting the shrubs in a location that offers some protection from drying winter winds. This could be near a building, fence, or other larger plants that can act as a windbreak. Alternatively, you can create a physical barrier using burlap or other materials to shield the plants from direct wind exposure.
Another preventive measure is to provide adequate moisture to the plants throughout the winter season. Even though the ground may be frozen, it’s important to water the boxwoods during dry periods when the temperatures are above freezing. This can help replenish any moisture lost through evaporation and reduce the risk of foliar desiccation.
In addition to protective measures, it’s crucial to maintain the overall health of the Green Velvet Boxwood. Ensure the plants are properly watered during the growing season, providing a deep soak rather than frequent shallow watering. Avoid over-fertilizing, as excessive nutrients can make the plants more susceptible to winter burn.
If your Green Velvet Boxwood has already turned brown due to winter burn, there are a few steps you can take to help it recover. Firstly, prune away any dead or damaged branches, making clean cuts just above a healthy bud or branch collar. This will promote new growth and improve the overall appearance of the plant.
It’s also important to continue providing proper care to the boxwood, including watering during dry periods and applying a layer of organic mulch around the base of the shrubs. Mulch helps retain moisture in the soil and provides insulation to the roots.
If your Green Velvet Boxwood is turning brown, it is likely experiencing winter burn. This can be caused by drying winter winds and foliar desiccation. Taking preventive measures, such as planting in a sheltered location and providing adequate moisture, can help avoid this issue. If browning has already occurred, pruning and continued care can aid in the recovery of the plant. Remember to closely monitor the health of your boxwoods and take action promptly to ensure their vitality and beauty.
