How to choose the best frost protection covers
Selecting the right cover involves matching the product’s specifications to your garden’s specific needs. The primary goal is to create a microclimate that shields plants from freezing temperatures while maintaining healthy growing conditions.
What to look for
- Material and Weight: Covers are typically made from breathable non-woven polypropylene fabric. The weight (e.g., 1.5 oz/yd² vs. 3.2 oz/yd²) correlates with insulation level—heavier fabrics generally provide more frost protection but may allow less light through. Ensure the material is listed as breathable to prevent moisture buildup.
- Size and Shape: Measure your plants’ height and width. For individual shrubs or trees, a fitted cover with a drawstring or zipper works well. For vegetable beds or rows, a large rectangular blanket you can drape and secure is more practical. Some large blankets can be cut to custom sizes.
- Closure and Access: Drawstrings help secure the cover at the base against wind. Zippers offer convenient access for watering or checking on plants without removing the entire cover, which is helpful for longer-term protection.
- Light Transmission: Plants still need light. Look for listings that mention light transmittance (e.g., 70-90% for floating row covers, 40-60% for heavier frost blankets). This ensures your plants can photosynthesize while covered.
- Versatility: Many covers serve multiple seasons, acting as insect barriers, sun shields, or animal deterrents in spring and summer. Check the listed uses to get more from your purchase.
For more on timing your seasonal garden tasks, see our Seasonal Gardening Guide. Always follow the manufacturer’s instructions for putting on and removing covers to avoid damaging plants or negating the protective effect. Remember, the cover traps heat radiating from the soil, so it’s most effective when placed over plants before sunset and removed on warmer mornings.
FAQ
What temperature can frost protection covers handle?
Protection levels vary by product. Some listings specify a temperature rating (e.g., “down to 2°F”), while others do not. The level of protection depends on the fabric weight, how well the cover is secured, and the duration of the cold snap. Heavier fabrics generally offer more insulation. It’s a good practice to check the specific product listing for any stated temperature guidelines.
Can I leave frost covers on my plants all day?
It depends on the cover and the weather. On sunny days, even breathable covers can cause overheating if left on. Most manufacturers recommend removing covers once temperatures rise above freezing during the day to allow plants full sunlight and air circulation. However, some heavier covers designed for winter-long shrub protection are meant to stay on for extended periods. Always refer to the usage instructions provided with your specific cover.
Are frost blankets reusable?
Yes, all the covers in our comparison are listed as reusable. They are typically made from durable, non-woven fabric designed to withstand multiple seasons. Proper care, such as drying wet covers before storage and handling them gently to avoid tears, will extend their lifespan. Check individual listings for any specific care instructions.
What’s the difference between a frost blanket and a fitted shrub cover?
A frost blanket is usually a large sheet of fabric that you drape over plants or rows and secure at the edges. A fitted shrub cover is shaped more like a bag or jacket, often with a drawstring or zipper, designed to enclose an individual plant. Blankets offer flexibility for covering irregular or grouped plantings, while fitted covers provide a neater, more secure fit on specific shrubs or small trees.
