When temperatures drop near freezing, even brief exposure can damage leaves, stems, and fruit. A few simple steps tonight can save your garden and help you enjoy more of your harvest.

Let’s get into it.

What Is a Frost Advisory?

A frost advisory indicates that overnight temperatures are expected to fall to levels that can cause frost to form on exposed plants. While some hardy plants tolerate these conditions, tender vegetables, flowers, and fruiting plants may suffer damage.

How To Protect Your Garden Tonight

1. Cover before sunset.
Covering plants while there is still daylight traps warmth from the soil.

2. Use breathable materials.
Sheets, blankets, pillowcases, or light cloths are ideal. Avoid plastic directly on plants, as it can cause freezing where it touches.

3. Anchor the edges.
Use rocks, boards, bricks, or other weights to prevent cold air from sneaking under the covers and to keep them secure against wind.

4. Do not crush plants.
Use stakes, cages, or other supports to keep the cover from resting on the leaves and stems.

5. Add extra insulation if needed.
For temperatures near freezing, layering a tarp or plastic over the cloth can provide extra warmth. Keep the cover from touching the plants directly.

6. Uncover in the morning.
Once frost has melted and the sun is up, remove covers to allow plants to warm and dry naturally.

When To Consider Harvesting

If frost is imminent and you prefer not to cover your plants, harvest any tender produce that is still ripening. This allows you to preserve the last of your harvest.

Final Thoughts

A light frost does not have to end your gardening season. With a few sheets or blankets and a little effort, you can protect most tender plants and enjoy your garden a little longer.

Plan ahead tonight and give your plants a fighting chance.

Plan ahead for next year and begin collecting old sheets, blankets, and other cloth.
