What to Do During a Frost Advisory
If a frost advisory is issued in your area, it’s essential to take action to safeguard your plants. The weather service recommends covering tender plants with blankets or other materials to trap heat near them. If possible, moving plants indoors will help prevent damage.

Be sure to prepare your outdoor space ahead of time to protect your plants from potential damage.
