Imagine going to all the trouble of removing a section of your lawn to plant it Garden bedOnly to see the grass reappear. When grass descends into the planting bed, it becomes a weed that competes for the same nutrients, sunlight, and space that your flowers and edibles thrive on. Grass can suffocate bedding plants and create a messy look. While chemical herbicides may seem like an easy way to deal with unwanted grass in your flower bed, there are safer approaches. Keep reading to learn how to keep grass out of flower beds without reaching for chemicals.

Cover the area with cardboard or newspaper.

You can tackle the rest of the grass in the area before you start with smothering your flower bed. Also known as layering or composting, smothering involves covering an existing patch of grass with several layers of overlapping cardboard or newspaper. This technique works by preventing any sunlight from reaching the grass Killing blades of grass and weakens their root system. Moisten the paper product before arranging it in the flower bed and anchor it with mulch, soil or rocks.

Keep in mind that it can take up to 8 weeks for the grass to die, so this method requires some patience, and if you already have plants in the bed, you’ll need to work around them carefully. Another benefit of using cardboard or newspaper is that it improves the quality of the soil as it breaks down.

Install the root barrier edge.

Installing a physical barrier between flower beds and the surrounding lawn can help keep weeds out. Grasses spread underground through rhizomes and stolons, explains Gaetano Virone, a landscaping and irrigation expert and founder and head. Environmental designers irrigation in Wall Township, New Jersey. Use a garden edging made of sturdy materials such as wood, steel, brick or stone to prevent grass roots from spreading into the bed. “Install a physical root barrier at least 6 inches deep around the perimeter of the entire bed,” Viron recommends.

Place landscape fabric in the bed.

Place commercial-grade landscape fabric under your soil or amendments, Viron says. This woven material effectively blocks sunlight to keep grass out. “I’ve seen homeowners skip this or go too budget-friendly, and then wonder why they’re pulling hay after two seasons.” To use it, first prepare the ground by removing any existing grass. Then place the fabric on the flower bed and hold it in place with staples or small garden stakes. “Overlap the seams by at least a foot,” says Viron. “Be sure to cut a hole big enough for the plant to go in. Garden bed.

Dig a steep trench.

Another safe alternative to herbicides is trenching. It involves digging a trench between the edges Garden bed and lawn, which creates a ditch so that grass cannot grow across the area. The best way to do this is to use a sharp shovel to dig 4 to 6 inches deep in a V-shape along the edge of the garden bed. For best results, leave the grass side of the trench vertical, but slope the flower bed side about 45 degrees. Keep the edge of the trench clean by mowing or mowing occasionally.

Add a layer of mulch.

Mulching is another way to suppress grass growth in garden beds. It acts as a barrier to prevent sunlight from reaching the grass seeds. Pine bark, shredded hardwood, straw and shredded leaves are recommended materials to use for mulching. The best way to prevent grass in the beds is to temporarily layer the new area with at least 8 inches of mulch (for about 4 weeks). After planting, add a 2- to 3-inch layer of mulch to your flower bed to prevent weeds from reappearing.

Set irrigation zones.

Viron suggests setting up irrigation zones for your landscape. “If your existing lawn zones are dumping water into the new bed area, you’re actively encouraging the grass to reclaim that land,” he warns. “Just redirecting or capping the heads to suit the needs of the new planting zone is something we look at almost every time. Residential redesign We do, and that makes a real difference in what takes root and what doesn’t.”
