Potted perennial plants face harsher winter conditions compared to those grown in the ground. Protecting them is essential to help them survive and thrive in spring.
Why Protect Potted Perennials
The roots of most plants are less cold-resistant than their above-ground parts. While soil insulates in-ground roots, potted plants have limited growing media, making their roots more vulnerable to freezing temperatures. To ensure survival, choose plants that are hardy to zones two levels cooler than your area.
Steps to Overwinter Potted Perennials
Prepare Plants and Pots
Water the plants well before winter sets in and check moisture levels throughout the season. This is especially important for evergreen plants to avoid winter burn. Moist soil freezes slower, offering better protection to roots.
Store Indoors
Move pots to cool, unheated spaces like a garage, shed, or basement. Ensure temperatures stay between 20°F and 45°F, as some perennials require cold dormancy for proper growth.
Sink Pots into the Ground
Place pots into the soil to insulate them from freezing temperatures. Mulch around the plants for extra protection. Remove them after the frost danger has passed.
Cluster and Mulch Pots
If sinking pots aren’t an option, group them in a sheltered area, like the north or east side of a building. Cover them heavily with straw, leaves, or mulch.
By following these methods, you can protect your potted perennials and enjoy their beauty again in the spring. Take time to safeguard your plants for a thriving garden year-round.
