Plant Frost Covers: A Complete Guide to Protecting Your Plants from Cold Weather
When temperatures drop unexpectedly, frost can severely damage plants — especially tender vegetables, flowers, and
young trees. Fortunately, plant frost covers provide an easy and effective way to protect your garden
from frost, wind, and freezing temperatures. This guide explains
what frost covers are, how to use them, and when to apply them for best results.
What Are Plant Frost Covers?
Plant frost covers (also called frost blankets or garden fleece) are lightweight fabrics designed to
trap warmth and prevent frost from forming directly on plants. They allow light, air, and moisture to
pass through while maintaining a protective layer of insulation. Frost covers are reusable and suitable for both
short-term and season-long use.

How to Use Plant Frost Covers
Frost Cover Properly Draped Over Plants
Step 1: Choose the Right Cover
Select a lightweight, breathable frost cover appropriate for the level of frost protection you need. Heavier covers
offer more insulation for severe cold.
Step 2: Apply the Cover in the Afternoon
Place the cover over plants before sunset to trap ground heat. Ensure it reaches the ground to prevent cold air from
getting in.
Step 3: Secure the Cover
Use stones, landscape staples, or soil to anchor the edges of the cover, preventing it from blowing away in wind.
Step 4: Remove or Ventilate When Warmer
Take off or lift the cover during warmer days to let plants breathe and receive sunlight.
