Prepare the perennial by cutting back dead foliage and mulching around the base. Choose a sheltered spot, cover with a thick layer of mulch, and protect with a frost cloth.
Monitor the plant throughout winter, ensuring the soil stays moist but not waterlogged. Remove snow from the top of the mulch to prevent excessive moisture. Insulate with additional mulch if needed.
In early spring, gradually remove the mulch and frost cloth as temperatures rise. Trim any damaged parts and provide a balanced fertilizer to promote new growth. Resume regular watering and care.
Check for signs of growth and adjust care accordingly. Keep an eye out for pests or diseases that may have overwintered with the plant. Enjoy the beautiful blooms of your perennial as it thrives in the new season.
Consider dividing the plant in the fall if it has outgrown its space or to rejuvenate its growth. Replant divisions in suitable locations for continued beauty year after year.
Follow these steps to successfully overwinter the longest lasting perennial flower in cold climates, ensuring a vibrant and healthy plant for years to come.
