Pull up any weeds that are already growing in the area you want to mulch. Use a trowel to help you remove the roots of the weeds, which will decrease how many try to grow back.
Things You Will Need
Rake the area smooth and remove any old mulch, rocks or debris that could poke a hole in your weed barrier.
Cut small “X” shapes into the weed barrier if you want to plant new plants in the area before laying the mulch. Dig a hole in each “X” shape and place one plant inside each hole.
Yes, you can. Synthetic landscape fabrics provide a physical barrier to weeds yet allow air, water and nutrients through to plant roots. Spread the fabric over bare soil around trees and shrubs; overlap several inches of fabric at the seams. Anchor the material with U-shaped metal pins, then conceal it with 1 to 2 in. of mulch, such as stone or bark chips.
Too little fertilizer can lead to sparse lawn that loses the competition with weeds. Too much helps nurture certain weeds, notably annual bluegrass, Bermuda grass and crabgrass. Strike a balance by following the application rates on the package. And use a fertilizer with a high percentage of controlled-release nitrogen, such as sulfur-coated urea, ureaform or IBDU. These provide a slow, steady nutrient supply.
Can I Put Landscape Fabric Over Weeds?
Controlling weeds is a fight you can’t win entirely because they always grow back. But you can keep weeds under control by depriving new ones of the conditions they need to take root in the first place. Let’s look at how to prevent weeds from growing.

Use Landscaping Fabric
Mulch is great for your landscaping needs — it can help to preserve moisture, improve the fertility and health of your soil, and add some aesthetic appeal to your front or backyard. Another main reason mulch is purchased is to prevent the growth of pesky weeds from terrorizing your plants. However, why is it the case that sometimes even after mulching that weeds can still grow through?
First, pull all the weeds you can find by hand that is directly residing in the area of your mulch. Any additional weeds that are exposed around the area should also be sprayed with a common herbicide or weed killer that contains glyphosate (most common weed killers contain this). Finally, you’ll want to apply a granular pre-emergent product to the mulch bed to prevent future weeds from growing. You can purchase a pre-emergent granular product at your local garden store
Pro Tip: Use a dyed mulch to have your mulch bed retain its color all year long!
Purchase High-Quality Mulch
In Columbia, Missouri Voss Landscaping uses and suggests triple-shredded hardwood mulch to prevent weeds from growing. Higher quality mulch typically contains larger materials and chunks in it. If used liberally, about three inches deep, your high-quality mulch should prevent any future weeds from surfacing.
One of the benefits of mulch is that it prevents weeds from growing in the first place. If weeds are piercing through your mulch-bed, it may be the case that you are using a cheaper or low-quality mulch. These are typically made with grass clippings, straw, or leaves as opposed to wood chips, bark nuggets, and sawdust
