As a gardening and landscaping expert, I can assure you that Mock Orange plants have the ability to survive winter in most cases. However, there are certain situations where they may need some extra protection to ensure their survival.
One such situation is when the Mock Orange plants are grown in areas with high snowfall. In such regions, the weight of the snow can potentially damage the branches or even break them. To prevent this, it is advisable to cover the plants with a protective layer. This can be done by using burlap or a frost cover to create a barrier between the plant and the heavy snow. This protective layer will help to distribute the weight of the snow more evenly, reducing the risk of damage to the plant.
Another scenario where Mock Orange plants may require winter protection is when they are planted near a building with a sloped roof. In such cases, the snow can easily slide off the roof and accumulate on the plants, causing harm. To avoid this, it is important to provide a physical barrier between the plants and the falling snow. This can be achieved by erecting a temporary fence or installing a snow guard on the roof to prevent the snow from sliding directly onto the plants.
Furthermore, if Mock Orange plants are grown at the lower end of their growing range, they may be more susceptible to winter damage. In such instances, it is recommended to provide extra insulation to the plants. This can be done by applying a thick layer of mulch around the base of the plant. The mulch will help to insulate the roots and protect them from extreme cold temperatures. Additionally, a frost cover or burlap can be used to wrap around the plant to provide an extra layer of protection against frost and freezing temperatures.
In my personal experience, I have encountered situations where Mock Orange plants have suffered winter damage due to heavy snow or freezing temperatures. However, with the appropriate protection measures, such as covering the plants or providing extra mulch, I have been able to successfully help the plants survive the winter.
To summarize, while Mock Orange plants are generally hardy and able to withstand winter conditions, there are certain situations where they may benefit from additional protection. This can include covering the plants with a frost cover or burlap in areas with high snowfall, creating a barrier between the plants and falling snow near buildings, or providing extra mulch and insulation for plants at the lower end of their growing range. By taking these precautions, the chances of a Mock Orange plant surviving winter are significantly increased.
