Many fabrics are UV-protected but will last longer if they are not directly exposed to sunlight. A layer of mulch or other ground material provides this coverage. Landscape fabric Landscape fabric staples Plants (optional) Mulch or other ground cover (optional) Instructions. Dig out all weeds, grass, and other vegetation, using a garden hoe, shovel, or other tool.
Dig deep enough to get the roots; if you miss the roots, some plants can spread even when covered with landscape fabric. Use a hoe with a swinging motion, bringing the blade down toward the ground and slightly back toward your body, striking the ground at approximately a 45-degree angle. Ideally, you'll penetrate the soil deeply enough to get under the roots and lift out the whole weed, roots and all. Alternatively, you can kill the plants with a non-selective, or broad-spectrum, herbicide (such as Roundup). Apply the herbicide as directed by the manufacturer, and allow time for the plants to die completely. Herbicide is often recommended for weeds that spread with rhizomes or stolons, which can be difficult to eradicate with digging alone. Rake the area thoroughly with a steel garden rake, also called a bow rake. Pull up any uprooted weeds and rake out all twigs, stones, and other sharp objects that could damage the landscape fabric.
Discard the loosened rocks and debris as you rake until the soil surface is smooth and flat. Roll out the landscape fabric so it is parallel to the long dimension of the area. Cut the material off of the roll, as needed, with a sharp utility knife (it helps to replace the blade frequently so it is always sharp). If desired, you can run the pieces long and trim them later; it's better to have too much fabric than too little. If you need more than one row of fabric, overlap the pieces by at least 6 inches. Fabric manufacturers may say 3 inches is enough, but 6 is better. If the fabric has different sides (such as one shiny and one dull side), be sure to install it with the proper side facing up, as directed. Temporarily weight down the fabric, if necessary, with stones or other heavy objects. Confirm that the fabric is positioned properly, then secure it with landscape fabric staples, using a hammer or small hand maul. Drive a staple every 10 feet, or so, along the edges and seams and as needed over the interior areas (keep in mind that your ground cover, if you are using it, will help hold down the fabric). Plant Through the Landscape Fabric (optional) If you're adding plants in the area, make an X-shaped incision in the landscape fabric for each plant, using scissors or a utility knife. Cut from the outside toward the center, and make the incisions just big enough for digging a hole for the root ball of the plant. The fewer and smaller the holes you put in the fabric the better. Pull the flaps aside to dig the hole, and dump the soil into a wheelbarrow or tub, rather than onto the surrounding fabric. Install the plant, back-fill around the root ball with soil, and lightly tamp the soil to eliminate air pockets. Lay the four flaps of fabric snugly against the base of the plant to cover the soil. Landscape fabric, while permeable, will likely limit the amount of moisture from rainfall or spray irrigation from reaching the soil below the fabric. When planting within fabric, keep a close eye your plants to make sure they are getting enough water. Add Mulch (optional) Cover the landscape fabric with mulch or other ground cover, if desired. If using natural mulch, such as wood chips or pine needles, add no more than about 2 inches of the cover. If using stone, you may need less than 2 inches for full coverage, depending on the stone and the planned use of the area. Spread and smooth the ground cover with a rake, being careful not to damage the fabric. Areas covered with landscape fabric need some maintenance to remain weed-free over time.
Soil and dust that blows onto the top of the fabric can build up and eventually support the germination of weed seeds. Any organic mulch applied over the fabric inevitably breaks down into soil, creating fertile ground for weeds and grasses. When the area becomes choked with soil and debris, it's time to remove and clean or replace the ground cover. Stone ground covers can be raked off and hosed down to remove accumulated dirt. For this reason, there's no sense in using a thick layer of organic mulch over landscape fabric because all mulch biodegrades and turns into soil; a thicker layer just means more soil that can harbor weeds as well as a higher replacement cost. And, because you have the landscape fabric to stop weeds from below, there's no benefit to having a thick layer of mulch on top, as you would use when trying to suppress weeds without fabric. "The secret to preventing weeds is to cover the soil with vegetation to prevent sunlight from reaching the soil and encouraging weed seeds to grow,” says landscape architect Patrick Devereux, co-owner of Stone Oak Landscapes in Cudahy, Wis. To minimize your time digging out weeds so you can recline on the deck and dig into the newest best-selling novel instead, all you need is a sound game plan. Plan ahead to reduce weeds Whether you’ve just dug up the planting beds near your cabin’s foundation so you can start with a fresh palette, or you’re planning a new bed, Devereux recommends selecting cultivars that grow closely together and get dense foliage so you don’t have a lot of mulch or bare soil between the plants.
You don’t have to stick with just one type of plant to create these solid groupings; using a variety will add visual interest.
