7 Tips to Protect Your Plants During a Freeze

A cold front is moving into Middle Tennessee and we will have a few chilly mornings, especially Thursday morning. Tuesday night, we will reach a low of 37 and Wednesday will remain cool with a high of 55. Temps drop again Wednesday evening to 35 and we’re expecting to have areas of frost Thursday morning. These frigid temps are lower than typical April weather and may kill crops and sensitive vegetation and possibly damage unprotected outdoor plumbing.

Check out our 7 plant protection tips:

1. Water the soil thoroughly (except around succulents). Wet soil holds heat better than dry soil, protecting roots and warming air near the soil.

2. Bed sheets, drop cloths, blankets and plastic sheets make suitable covers for vulnerable plants. Use stakes to keep material, especially plastic, from touching foliage.

3. Remove the coverings when temperatures rise the next day.

4. For a short cold period, low plantings can be covered with mulch, such as straw or leaf mold. Remove once the danger of frost has passed.

5. Place a 100-watt lamp designed for outdoor use in the interior of a small tree. It can emit enough warmth to reduce frost damage. Holiday lights (not the LED type) serve a similar function, but be sure they don’t touch any covering materials.

6. Spray an anti-transpirant, available at your local nursery, on the foliage of cold-sensitive plants to seal in moisture. One application can protect up to three months by coating the leaves with an invisible polymer film.

7. Cluster container plants close together and, if possible, in a sheltered spot close to the house.
