3 Ways to Stop Weeds from Growing in Mulch

3 Oct 18

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?

There are several reasons why weeds may be breaking through your mulch bedding. Follow our tips below to discover the reasons why and the best ways to prevent them from showing up again in the future!

Remove Weeds from an Existing Mulch Bed

If you already have planted your mulch and are seeing weeds growing through it, this could be for a number of reasons. It could be that your mulch is low quality, your bed isn’t thick enough, or your mulch is older and breaking down. Regardless of the cause, you’ll want to start by manually dealing with the problem

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

Purchase High-Quality Mulch

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

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.

Pro Tip: Use a dyed mulch to have your mulch bed retain its color all year long!

Use Landscaping Fabric

Another sure-fire way to prevent weeds when planting your bed is to employ the use of a landscaping fabric. Landscaping fabric is a thin textile you can purchase at most local garden stores and is designed to prevent the growth of weeds by blocking sunlight to them.  

Once you have planted all trees, shrubs, or bushes in the area you will want to cut the fabric to size before you begin the mulching process. Since the material is relatively thick it should be easy for you to cut and shape it to fit perfectly in the location. Once in place, you’ll want to spread mulch as normal and cover the fabric completely. This will help to prevent weeds for up to 5 years depending on the type of landscaping fabric you purchased.
