Do You Have to Remove Weeds Under Weed Fabric?

Landscape fabric, also referred to as grass fabric, which is a thin barrier that allows moisture and air to the ground, while blocking sunlight and preventing many weeds. It is a semi-permanent solution best suited to perennial beds, since the fabric continues for at least five years prior to it requires replacement. You do need to eliminate any weeds from under the cloth before you install it, and only light weeding is required once it’s installed.

Catch Them Early

Weed removal before placing down the grass fabric prevents mature weeds from continuing to develop underneath the fabric. If the weeds are not pulled, they may eventually develop through the cloth, especially if the material is thin or contains an open mesh. When pulling up weeds, remove the top stem and the root system. Many weeds can develop from root departments left at the ground, which might develop through the fabric mulch after it’s installed.

Digging Deep

More involved weeding may be necessary in case your garden bed is especially weedy or contains a particular stubborn weed like nutsedge (Cyperus esculentus), that rises in U.S. Department of Agriculture plant hardiness zones 8 through 10. Tilling the soil before installing the cloth turns up any concealed weed seeds and tubers. These may sprout and grow under the cloth, eventually ripping through. Allowing the soil to dry out can ruin tubers of moisture-loving weeds like nutsedge, or you can cover the site with clear plastic for a single month during the sunniest and hottest aspect of the year to heat and kill the seeds and roots turned upward by tilling.

Keeping Up Appearances

Any weeds that begin to develop through the cloth after it’s installed need immediate drawing so that they don’t further harm the integrity of this cloth. Leaving the weeds when they’re young prevents them from causing a larger hole in the cloth and makes it easier to remove the whole root system. If a hole is left in the cloth, lay a brand new piece of landscape cloth over it as a spot. You may anchor down the patch with a U-shaped landscape stake. Weeds are more inclined to rise in and around the base of crops than through the cloth. Examine the dirt around the base of plants and below the edges of the fabric around the planting hole to get sprouting weeds, and pull them as soon as you visit them so they don’t become established.

In the Top Down

Organic or inorganic mulch is usually spread in a thin layer above the top of fabric. The mulch enhances the appearance of the material, and also helps protect it from harm. Organic mulch will gradually decompose, and dirt and decaying plant material will gather on top the cloth under the mulch layer. Weeds can germinate in this thin layer of compost and soil. Though they begin shallow-rooted, eventually the roots will grow through the cloth, which weakens it and also can cause more weeds growing underneath. Pull up any weeds that germinate on top the cloth after you spot them. Additionally, avoid cutting holes in the cloth unless you intend to plant in the hole immediately so weeds don’t invade the bare dirt.
