Frequently Asked Questions
What is landscape fabric?
Landscape fabric is a material placed around trees, flowers or shrubs to stop weeds and promote plant growth, without chemicals. It blocks sunlight so weeds can't grow, but it's also permeable so air and moisture can nourish your plants. Professionals have used it for years, and now it's growing in popularity among home gardeners and landscapers.
Is landscape fabric really better than plastic?
Yes! While black plastic does stop weeds, it also keeps air and water away from the soil, so plant-killing diseases develop. Landscape fabric blocks weeds, but its permeability allows the proper balance of air, water and nutrients into the soil. As a result, plants can grow up to twice the size of plants grown without fabric.
Are there different qualities in the fabrics available?
Yes. Our Pro Weed barrier is the only one with a 100% guarantee against no weeds. We carry two types of fabrics, non-woven and woven. The non-woven product is a consistent fabric that is fabricated by using a spun-bonded method, which sandwiches melt-blown material. The woven product is a tightly woven mesh that is strong and can handle even the toughest weeds. DeWitt Company Inc products are all U.V. treated to withstand the sun's decomposing effects. A rule of thumb: see the fabric's guarantee. The longer it is, the better it is.
What makes DeWitt fabrics better?

Will weeds grow on top of the fabric?
Weeds will grow anywhere there is an organic environment present that will allow germination. If wind blows soil and seeds onto the surface of any fabric or mulch covering, there is the possibility of weed growth. Mulch itself will eventually break down and create a soil-like environment for weed seed germination. Solution: Quick application of systemic herbicide and later application of early spring or late fall pre-emergence herbicide. Follow the directions on the label.
What if weeds grow under or through the fabric?
The primary causes are improper fabric application and sometimes extremely stubborn perennial weeds or grasses. Be sure to follow the recommended fabric application directions to fully cover the entire area. In the rare case of particular weeds actually growing under or through the fabric, a herbicide application may be needed. Solution: Application of herbicides may be necessary in particular installations. The use of a plant fabric will prevent most weed growth and limit the need for chemicals. DeWitt fabrics are the best available at any price.
Does it matter which side of Pro5 or Weed Barrier 20 yr. I put against the ground?
Pro5 ™ and 20 yr. Weed Barrier should be installed with the fuzzy side facing the ground. You can also lay the fabric both ways if you are on a slope and you are wanting things to stay in place.
I have put landscape fabric down and water is not going through. Why?
The manufacturers put a coating on the material to make it roll better. After 24-48 hours, this will break down and the water will go through normally.
If I use DeWitt landscape fabric do I still install the same amount of organic mulch?
No. You can reduce the amount of mulch you use by about 1/3. Example: Normal use of 2.5" would only require 1" to 1.5" with DeWitt landscape fabric. This is a cost savings to you.
How far apart should I space my anchoring pins?
Generally, every 3 to 5 feet apart is sufficient. If you have questions that have not been addressed here, please contact DeWitt for answers or additional information. DeWitt Company™ welcomes your interest in its landscaping fabric and horticultural products.
