Trim back any dead foliage and remove weeds around the plants. Mulch around the base to protect roots from freezing temperatures.
Water your perennial flowers deeply before the ground freezes to provide moisture throughout the winter. Consider using a soaker hose for even watering.
Protect delicate plants by covering them with a layer of burlap or a frost cloth. This will shield them from harsh winter winds and frost.
Consider dividing overcrowded perennial plants in the fall to promote healthier growth in the spring. Replant divisions in well-draining soil.
Monitor your perennial flowers throughout the winter for signs of stress or damage. Remove any heavy snow buildup to prevent breakage.
By following these steps, you can ensure that your perennial flowers survive the winter and thrive again in the coming spring.
