Park's Plant Frost Protector Film
Start spring crops earlier and keep fall crops growing longer!
Light enough to cover most any crops with no support, it can also be stretched across support hoops. Just cut it to the size you need (or roll up the excess) and reuse many, many times! Perfect for direct-sown crops, too, to prevent seeds washing away or being eaten by birds.
This white plastic fabric is available in 2 different sizes.
