Protecting Tender Annuals from a Late Freeze in Alabama

Emergency Frost Protection for Petunias, Geraniums & Roses

With lows near freezing and daytime highs only 40–45°F, here's the practical plan:

1. Cover at Night

• Use lightweight painter's plastic (drop cloth weight) over all tender plants.
• Secure edges with bricks/soil. Remove each morning.
• Roses just breaking dormancy benefit from covering too.

2. Daytime Garage Storage?

• If days stay ≤45°F, keep pots in garage during the day as well.
• If days reach 50°F+, set outside in sun but cover at night.

3. What Can Take a Light Frost

Petunias, geraniums, snapdragons, dianthus can survive a brief 30–32°F dip if acclimated. Impatiens, begonias, coleus cannot—keep them protected.

4. Long-Term Prep

Keep plastic sheeting on hand. Increasing temperature swings make this an annual ritual.
