How to Protect Hydrangeas From Winter Frost

One common reason why hydrangeas fail to bloom during summer is winter frost. Hydrangea buds are sensitive to cold. When the temperature falls below 25 degrees fahrenheit during winter, you can lose the hydrangea buds. Protecting your hydrangreas against the winter cold is extremely important. hortensia verzorgen

Trimming the Hydrangea Bush

Keeping your hydrangeas safe through the winter starts before August. Towards the end of summer, trim your hydrangea bushes to remove dead and weak branches. Cut close to the base of the stem you want to trim off. Be careful not to snip off the healthy branches because this is where the flowering buds are located.

Insulate your In-Ground Hydrangeas

To keep your hydrangea from freezing in the cold, create insulation all around your hydrangea bush. One way to do this is by using chicken wire and dried leaves.

What you do is you stake sticks around the perimeter of your hydrangea bush. The sticks should be about 10 inches taller than the bush once planted into the ground. Next, put chicken wire around and on top across the sticks, completely surrounding the hydrangea bush. Finally, carefully fill the cage with pine needles and leaves to insulate your plant.

Many home gardeners recommend using oak leaves because they tend to stay in place better than other types of leaves. Do keep bags of dried leaves in your store room throughout winter to replace the leaves that settle in your insulation.

When insulating your plant, be careful not to damage the ends of the branches. These are where the flowering buds are located. You do not want to inadvertently damage or snap off these buds.

Protection for Potted Hydrangeas

The best way to protect your potted hydrangeas from the winter frost is to bring them indoors before autumn ends. Sometimes, because potted hydrangeas may be too large to easily move, you have to keep them outside during winter. In this case, should still insulate them.

To insulate potted hydrangeas, what you do is you first fill in the plant in between its branches with dried leaves. Next, compress the plant by tying the branches together with a rope. Make sure the branches are snug but not too tight. Next, get some foam insulation to wrap around both the plant and the pot. Make sure the sides and the top are covered.
