Buying Guide
What size should I choose?
Consider bed width and length. Larger sizes save time on multiple rows but may require more anchor points. Hooped kits add rigidity for taller plants.
What fabric thickness is right?
0.55 oz/yd² is light and breathable, good for mild frost and seedling protection. 0.9 oz/yd² is thicker and more durable for heavier frost and wind, but may reduce light slightly.
Do I need hoops or frames?
Hoops simplify installation and reduce fabric contact with foliage. If you don’t want frames, choose a flat cover with adequate anchoring in calm conditions.
How should I install and secure covers?
Lay the cover over plants and stake the edges with rocks, soil, or garden staples. For longer runs, use hoops every 3–6 feet and secure with ties or clips.
How long can covers stay in place?
Most covers are designed for seasonal use. Remove in warm weeks to prevent overheating or disease buildup and wash between seasons to extend life.
