Frost can be a serious threat to your outdoor plant box, especially during the colder months. To keep your plants safe, follow these practical steps:

1. Use Frost Covers or Blankets: Cover your plant box with breathable fabric or specialized frost blankets overnight to trap heat and shield plants from freezing temperatures.

2. Mulch the Soil: Apply a thick layer of mulch (straw, leaves, or wood chips) around the base of your plants to insulate the roots and retain soil warmth.

3. Water Before Frost: Moist soil holds heat better than dry soil. Water your plants in the afternoon before an expected frost to help them stay warmer.

4. Move Potted Plants Indoors: If possible, relocate portable plant boxes to a sheltered area like a garage or porch during extreme cold spells.

5. Install Windbreaks: Place barriers like burlap or wooden panels around your plant box to reduce wind exposure, which can worsen frost damage.

By taking these precautions, you can minimize frost damage and keep your outdoor plant box thriving even in chilly weather. Stay proactive and monitor weather forecasts to act in time!
