Preparing Your Garden for the Weekend Freeze

A significant freeze is headed for North Georgia and the Fayette County area this weekend, bringing the coldest temperatures of the season so far. With overnight lows projected to plummet into the upper 20s and low 30s on Saturday, November 14 and Sunday, November 15, tender landscaping and potted plants face the threat of frost damage. Taking a few proactive steps before sunset on Friday will make the difference between a thriving spring garden and a landscape of dead foliage.

1. Move Containers Indoors -The simplest line of defense is relocation. Bring all potted tropicals, succulents, ferns, and annuals inside your home, garage, or a basement to shield them from wind chill and direct frost formation. I plan to do this with my pots filled with blooming Sunpatiens. They still look great and I would like to see them add some color through Thanksgiving.

2. Water the Soil Deeply – It sounds counterintuitive, but you should water your garden beds thoroughly on Friday morning. Wet soil traps heat much better than dry soil. As the moisture evaporates slowly overnight, it releases latent heat that radiates upward into the plant’s root zone, keeping the surrounding air a few degrees warmer.

3. Cover Vulnerable Vegetation – For newly-planted shrubs, like young camellias, hydrangeas, or late-season vegetables, construct a protective tent. Use breathable fabric materials such as canvas drop cloths, old bedsheets, or burlap. Avoid using raw plastic directly against the leaves, as it conducts cold and can scorch the foliage wherever it touches. Anchor the fabric edges firmly to the ground using bricks, landscape pins, or rocks to trap the rising earth warmth completely.

Taking some time to prepare your yard before the cold front hits will preserve your hard work and keep your garden from damage through the weekend chill.
