Last-minute protection from frost
Easy ways to keep container plants safe
When a freeze is predicted and you need to quickly protect tender container plants, try this method.
1. Grab a tomato cage from storage and invert it over your container as shown, so the ends stick up in the air. (Placing a small cafe table or an outdoor chair ― right side up ― over the plant would also work.)
2. In the evening, drape thick plastic, burlap, or other fabric over the cage, making sure it doesn’t touch the plant’s foliage.
