Even if you lovingly care for your plants throughout the year, giving them water, sunlight, and nutrient-rich soil, cold temperatures can quickly lay waste to your hard work. To ensure your plants enjoy as long a growing season as possible, it’s important to protect them as best you can against frosts and cooler temperatures. Plant blankets and frost covers are designed to do just that, while still being breathable enough to allow for ventilation. Plus, if used correctly, they can also be effective at preventing insect damage and deterring rabbits or deer that see your plants as a morning snack.
Plant blankets are usually available in a range of sizes, so if you don’t see the dimensions you want in our coverage, it should be easy to select an alternative size.

This 0.74-ounce blanket is ideal for those looking for a light-duty plant cover to use somewhere that doesn’t get particularly cold or windy. This frost blanket’s light weight makes it simple to work with, easy to cut, and safe to use with delicate plants that you don’t want to be crushed.
Its 10 by 30–foot size is big enough to cover long rows, and it’s great for doubling up if you want a bit more protection. In addition to providing frost protection, this cover is also suitable for deterring insects, but still allows enough sunlight to stream through.
