Phlox is a beautiful perennial that can add vibrant color to your garden year after year. Proper wintering ensures your phlox survives the cold months and blooms beautifully each spring. Here are the top 10 tips to winter your phlox with confidence.
1. Choose Hardy Varieties
Select phlox varieties that are hardy in your USDA plant hardiness zone. This increases their chances of surviving winter without extra protection.
2. Plant at the Right Time
Plant your phlox in the early spring or fall, giving it enough time to establish roots before the cold weather arrives.
3. Improve Soil Drainage
Ensure well-draining soil to prevent water from pooling around the roots during winter, which can cause rot.
4. Mulch Heavily
Apply a thick layer of mulch, such as straw, wood chips, or shredded leaves, around the base of your phlox to insulate the roots from extreme cold.
5. Cut Back in Fall
In late fall, trim back the dead or damaged stems to reduce disease risk and prepare the plant for dormancy.
6. Water Before the Freeze
Give your phlox a deep watering before the first hard frost to ensure it is well-hydrated going into winter.
7. Protect with Coverings
Use burlap or frost cloths to cover your phlox during especially harsh cold snaps for extra protection.
8. Avoid Fertilizing Late
Refrain from applying fertilizer late in the growing season, as this can encourage new growth that is vulnerable to winter damage.
9. Check for Pests and Diseases
Inspect your phlox regularly in fall for signs of pests or diseases and treat any issues promptly before winter sets in.
10. Plan for Early Spring Care
Once winter ends, remove mulch gradually and prepare your phlox for vigorous growth and blooming in the spring.
