It won't lose any of that ability by retaining moisture <br />and it*s hard finish won't silt in either. So Typar can be counted on <br />to continue breathing well for years of dependable service. <br />T^Y THIS <br />Wet a piece of Typar (there's a sample enclosed). Shake it and lay it <br />out to dry. It will dry quickly, the water that clings is just surface <br />water - the fabric hasn't absorbed it. <br />Now wet a competing spunbond, woven or needle punched fabric - wring it <br />out and lay it out to dry. If water isn't beading on the surface of the <br />fabric, it has absorbed water. Then note liow much longer it takes to dry <br />than Typar. If it will absorb that much water from a few seconds exposure, <br />imagine how much moisture that material is going tn hold in a heavy soil <br />UNDER A LAYER 01' NOLCIl. Natural evaporation is very important to plant <br />health, it's the major reason to use a "breathing” weed barrier. <br />BREATHABILITY IS IMPORTANT TO YOUR PLANTS <br />Without good air movement plants won't grow well. in some sev^ere cases <br />plants will actually be killed. We've seen this effect when black poly <br />is used over a heavy soil. The soil gets heavier and wetter and more so <br />until the ^i^nts begin to show a yellow color and finally fail. While <br />the problem isn't always that severe, plants will perform better wb <br />a breathable weed barrier is used that will allow near normal absorption <br />and evaporation of water. <br />TYPAR PREVENTS WEEDS <br />While no product can probably be consiviered ”100*^ weed proof (weeds even <br />penetrate blacktop roadways) Typar's performance is excellent. In a com­ <br />parative test last summer, for example, Typar performed at the top of the <br />group. <br />A wooden frame was constructed in which 3x3* squares allowed random <br />placement of several weed barriers. Each fabric was used in at least <br />two of the squares. The frame was then placed over an area containing <br />e variety of native weeds. In order to simulate the worst poirible <br />landscape conditions a very weedy area was chosen and the weeds were <br />not treated in any way before covering them with the fabrics. The <br />squares were then filled with a mulch material over the weed barrier <br />to the depth of the 2x4 frame. Watering was provided in the same <br />frequencies as new pMntings would be watered. <br />The black polyethelene - (both 4 mil and 6 mil) were the first to fail <br />within just a couple of weeks rhizome types of grasses, especially nut <br />sedge, began to penetiate them. The woven and needle punched polyeth­ <br />elene material was penetrated by nutsedge in the sixth week. Both the <br />black plastic and the woven poly material event* y allowed several <br />varieties of weeds to penetrate. <br />? <br />>;4 <br />Z' <br />* \ <br />. ^1.
