Row covers can keep troublesome pests of spring vegetables, such as spinach leafminer, from damaging the leaves. Other early pests that can be screened out include aphid, leafhopper, cabbageworm, and cabbage looper. Summer pest protection is offered against squash bug, cucumber beetle, bean beetle, corn earworm, grasshopper and whitefly.
This lightweight fabric provides an effective screen to reduce damage from flea beetles, thrips, aphids, whiteflies, striped cucumber beetles, and other insects that are virus vectors. Porous to both air and water. It allows 90-93% light transmission without heat build up and is UV stabilized so it won't deteriorate quickly.
Using Garden Fabrics in the Summer
Floating Row Cover are Multipurpose Summer Sheets for the Garden. It can protect new seeds or cool-weather crops from harsh summer heat/sun. Shade over a bed can create a cool microclimate that will help prevent bolting and bitterness in heat-sensitive crops such as lettuce and spinach, make it possible to grow warm weather crops in areas with very hot summers, and hasten germination of cool-weather fall crops.
Most states will face the first frost in late August or early September, some states may be delayed to October, or even November. Preparing in advance is pretty important. Protecting plants with row covers can provide a means to modify the environment around the plant, prevent losses from untimely frosts and freezes. Made of Polypropylene, row covers can give as much as 8 degrees of frost protection at both ends of the gardening season.
Row covers create a Micro-Climate, make it possible to produce earlier crops in the spring, grow cool-season crops in summer, maintain production well into the fall, and even harvest crops through the winter.
Heavier row cover fabric can be used to extend the growing season for a variety of crops, including cucurbits, lettuce, edible-pod peas, carrots, radishes and others. With a little luck from the weather and help from Row Covers, you can enjoy cool-weather crops right into early winter. What a treat it is to pick fresh lettuce, spinach, chard, cabbage, beets, kale, herbs, radishes, carrots and turnips even after the first snow-fall.
Reusing Garden Covers
Most covers will last one or two seasons. You can extend their life by keeping the edges pinned securely, and in windy areas, securing the fabrics tightly over hoops. When not in use, garden fabric should be folded and stored away from sun and moisture.
