Polypropylene Row Covers For Market Gardeners And Home Gardeners
 ✖  |
Pam Dawling, Louisa, Va.: “Polypropylene row covers are a good buy for market gardeners and home gardeners alike. They last longer and are tougher than polyester. Our favorite is Dupont’s Typar Xavan T131. It has lasted 6 years or more at Twin Oaks Community’s 3 1/2-acre vegetable garden. It transmits 75 percent of the light.
“We also like Agribon 19 spun-bonded polypropylene. It weighs less than half as much as Typar and lets in 85 percent of the light.
“The row covers are great at extending the season. For example, Agribon 19 offers 4 degrees of frost protection. They’re also great at protecting plants against insects and cross-pollination.
“ProtekNet insect mesh made by Dubois Agrinovation is an alternative to row covers in warm weather. Lighter weight versions are translucent nylon, and heavier ones are made from polyethylene. They come in 5 different mesh configurations and sizes and let in water, light and air. Different pests require different versions, sizes and shapes of mesh.
“We’ve used it to protect nursery seedbeds, cucurbit sowings, broccoli and cabbage transplants and more. It also shields plants from the sun, helping them recover from transplant shock. When no longer needed, it gets packed away for future use.
“Shade cloth is another good buy. It is available in a wide variety of widths and densities. It can be knitted or woven polypropylene or polyethylene, but knitted is about 25 percent lighter and won’t unravel when cut. We use 45 to 50 percent (light transmission) shade cloth over hoops for our summer lettuce. We use clothespins to attach it to the hoops, and once a bed has been harvested, we move the hoops and shade cloth to the next bed.
“Very dense (80 to 90 percent) shade cloth is great for covering produce on its way to the cooler.
“Shade cloth has been shown to increase pepper production, and Farmtek Growers Supply (www.farmtek.com) offers a great set of guidelines for use of various densities of shade cloth. Gemplers (www.gemplers.com) also sells a good range of shade cloth. For small areas, we’ve used scraps of window screen and old tent mesh windows. Anything is better than nothing!
