Buying Guide
What size should I choose?
Match the blanket size to your garden area. Larger plots require bigger covers (10×30 ft or similar) to minimize seams and ensure full protection. For irregular shapes, consider a larger size you can cut down to fit.
What fabric weight is best?
Fabrics range from 0.9 to 1.2 oz/yd². Lighter weights offer better light transmission and airflow but may require more careful anchoring in windy areas. Heavier fabrics provide stronger frost protection but can reduce light reach if coverage is too dense.
How do I secure these covers?
Use landscape pins, stones, or weights to hold the edges. Hoops or frames help prevent cover contact with plant foliage and improve airflow. For trees and shrubs, wrap and secure with pins or tie-downs to prevent wind damage.
How long can I leave a frost cover in place?
Most covers are designed for seasonal use. Remove or adjust during warm days to prevent overheating and ensure adequate air exchange. In early spring, you can speed up germination by gradually exposing plants to increasing temperatures.
Maintenance and reuse
Most covers are reusable across seasons with proper cleaning and storage. Avoid sharp objects that could tear the fabric. Inspect seams and edges for wear and repair as needed to extend life.
FAQ
