# Best Plant Frost Covers Source: https://balconygardenpicks.com/best/best-plant-frost-covers Updated: 2026-09-15 Publisher: Balcony Garden Picks. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://balconygardenpicks.com/how-we-research#our-score Container plants on a balcony feel the cold faster than those in the ground, since roots sit exposed in pots with air on every side. Frost covers give them a protective layer through cold snaps, helping tender herbs and flowers survive into the shoulder seasons. Breathable fleece lets plants breathe while trapping warmth, unlike plastic that can cause condensation. Look for drawstring or pot-fitting styles that stay put in wind, and a size that suits your containers. Reusable covers you can lift on and off make it easy to protect plants overnight and uncover them by day. ## Picks ### 1.
