Prepare your perennial flowers for winter by cutting back dead foliage and adding a layer of mulch to protect roots from freezing temperatures.
Consider dividing overcrowded perennial plants in the fall to promote healthier growth and prevent disease in the upcoming season.
Water your perennial flowers deeply before the ground freezes to help them stay hydrated throughout the winter months.
Protect delicate perennial flowers from frost by covering them with a breathable fabric or using a frost cloth during cold nights.
Remove any fallen leaves or debris from around your perennial flowers to prevent pests and diseases from overwintering in your garden.
Check on your perennial flowers periodically during the winter months to ensure they are not suffering from frost heave or dehydration.
