When frosty weather approaches, take fast and effective steps to protect your flowering bushes from freezing. By constructing a tent with a plastic or cloth tarp, you can cover flowering bushes for frost and save your landscaping plants from damage. When you protect plants from frost, you extend the growing season by several weeks and will continue to enjoy your beautiful landscape.
Pound the stakes into the ground around the flowering bushes. If you have only one flowering bush, one stake will suffice. If you have a row of flowering bushes, pound stakes approximately 5 feet apart along the row of bushes. Pound each stake into the soil 6 inches. Your stakes should be 2 feet taller than the bushes.
Place the tarp or sheet over the stakes to create a tent. For best results, create the tent over the bushes so there is at least 1 foot of empty space between the tarp or sheet and the tops of the bushes. This empty space will serve as warm insulation for the bushes.
Pull the sides of the tarp or sheet down to the soil and secure the tarp or sheet with bricks or rocks so it will not blow away.
Leave the tarp or sheet over the bushes until the following morning when the temperature moderates. Remove the cover from the bushes when the temperature reaches at least 40 degrees Fahrenheit.
