  • Straw or Mulch: A thick layer of straw or mulch can be spread around the base of plants to provide insulation from the ground up.
  • Cardboard Boxes: For smaller plants, cardboard boxes can serve as a quick and effective protective covering.

How to Properly Cover Plants

To maximize the effectiveness of your coverings, follow these guidelines:

  1. Cover Before Nightfall: It is essential to cover plants before temperatures drop to ensure they retain heat.
  1. Secure Edges: Use rocks, bricks, or soil to secure the edges of your coverings to prevent them from blowing away.
  1. Remove During the Day: If temperatures rise during the day, remove coverings to allow plants to breathe and receive sunlight.
  1. Avoid Contact with Foliage: Ensure that any covering material does not touch the leaves, as this can cause frost burn.
  1. Monitor Temperature: Use a thermometer to monitor the temperature around your plants to determine the effectiveness of your coverings.
