Apply a 2- to 4-inch layer of organic mulch over the entire surface of the black plastic weed barrier. Spread the mulch over the edges of the weed barrier so the black plastic doesn’t show.
Use several layers of old newspaper in place of black plastic weed barrier if you want a more environmentally friendly way to reduce weed growth through your mulch. Lay the newspaper down and cover with a 2- to 4-inch layer of organic mulch. You’ll have to replace the newspaper and mulch more often, however, because the newspaper will biodegrade over time. Fabric weed barriers are another option, though they aren’t always as effective as plastic in preventing weeds from growing.

Things You Will Need
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.
Weeds are the enemy of gardeners around the country. These pesky plants decrease the beauty of your yard and rob vital moisture and nutrients from your flowers, vegetables and lawn. Mulch helps minimize weeds but also retains more moisture and helps moderate the temperature of your soil. The trick to keeping weeds from growing through your mulch is to put a layer of weed barrier underneath.
Spread a layer of black plastic weed barrier over the planting area. If you already have plants growing in the area, cut holes in the black plastic to fit over them.
Overlap the strips of black plastic weed barrier so weeds can’t sneak their way through the edges of the material.
Rake the area smooth and remove any old mulch, rocks or debris that could poke a hole in your weed barrier.
Your landscaping adds a lot of beauty to your property and you likely appreciate them for their aesthetic appeal. That is until you start seeing weeds creep in. Weeds are an eyesore that can really detract from the overall look of your landscape beds.
How to Stop Weeds from Growing in Mulch
For instance, if you are dealing with Monkey Grass, we have a specialized control product to address that. If you have Nutsedge creeping into your plant beds from the lawn, we can mix up a specialized product to handle that. Our technicians are trained to know what products to use, where to apply them, and when to apply them—as all of these details matter. Keep in mind that because different seasons produce different weeds, it’s important that products are rotated based on season, too.
Enhancing the Health of Your Flower Beds
Hand-pulling can be time consuming and fortunately, it is not your only option.
Applying mulch every spring makes sense on several levels. It helps enrich the soil and helps retain moisture during the dry summer months. But the main reason most of us mulch is weed control. We faithfully lay down a couple of inches of mulch and cross our fingers that we’ve won the battle. But most of us aren’t so lucky: weeds almost always find a way to pop up, even in the most beautifully mulched landscaping. Why are weeds so hard to tame, and what can you do to stop them? Here are a few tips:
Why Do Weeds Grow In Mulch?
For flower beds and landscaping, we like a chipped or shredded bark mulch with a relatively coarse texture. It decomposes relatively slowly and doesn’t blow away so it can do its job and keep sunlight from reaching the soil. Inorganic mulch (like stones or gravel) does an excellent job of preventing weed growth. However, it doesn’t offer the soil-improving benefits of organic mulch.
What’s the Best Mulch to Prevent Weeds?
We all know how tenacious weeds can be. They thrive on the very same things your garden does: sunlight, water, and nutrients in the soil. Weeds take pretty much any opportunity to grow and aren’t picky about where they take root. As plant-based mulch decomposes, it provides an attractive, nutrient-rich environment for weeds to take root.
