Yes, using landscape fabric under rubber mulch is highly recommended by many suppliers and landscapers to prevent weeds and stop the rubber from sinking into the soil, creating a more stable, long-lasting barrier, especially for play areas; however, some gardeners dislike fabric because weeds can still grow on top (from windblown seeds) and become hard to remove, while it also hinders soil health and natural mulch decomposition.
Landscape fabric will keep your rubber mulch from sinking into the sand and substrate, but weeds don't always need soil to germinate, most just need moisture, which is why you still have to weed gravel paths and the like.
Install Landscape Fabric Barrier. Placing a landscape fabric as a separation barrier between your mulch and dirt is crucial. One of the most important parts of keeping your mulch bed looking new is preventing weeds from germinating. A landscape fabric or weed block reduces the amount of upkeep you have to do.
Landscape cloth is not conducive to planting new plants, transplanting or dividing existing plants. An area that has landscape fabric is a nightmare to plant in. You have to cut through the fabric in order to place new plants.
Cons of Rubber Mulch
Rubber mulch can also get very hot in the sun. This can be problematic for plants that prefer cooler soil temperatures. Additionally, there are concerns about the potential leaching of chemicals from the rubber into the soil.
It Suppresses Weeds
One of the primary jobs of mulch is to keep weeds at bay, and rubber mulch does this job admirably. As long as you add a thick layer of rubber mulch over your garden, it will block sunlight and prevent weeds from germinating, killing them before they can grow and spread.
Unlike wood or gravel, closed-cell sponge rubber mulch doesn't absorb water, ensuring fast drainage and preventing puddles, mold, or mildew. It stays resilient under heavy use, resists breakdown, and is made with safer materials than recycled tire mulch.
To put it simply, you should put a layer of organic material at the bottom of your garden bed, which will break down and enrich the soil. This can include compost, or woody material such as logs, dry wood, branches, and leaves.
Pine needles, grass clippings, and shredded leaves are free alternatives to landscape fabric. They're also environmentally friendly and easy to spread in your garden and flower beds. Pine needles, mulched leaves, and recycled grass clippings prevent soil erosion, hold onto moisture, and enrich the soil with nitrogen.
Yes, landscape fabric is entirely water permeable. Landscape fabric is made up of thin strands of plastic that are woven together and allow water and air through it. In heavy rain events, landscape fabric will drain water slower than usual, but it does not entirely stop water from draining.
Mulch glue, mulch adhesive or gravel binder is a product you spray onto mulch and other materials to hold them in place. Mulch glue offers two key benefits: Mulch glue makes it easy to blow loose leaves and debris from planting beds and walkways without disturbing the mulch.
Safety First
When playground rubber mulch is used at its recommended depth of at least six inches, it offers superior fall protection. It's twice as effective as wood mulch and three times better than sand. This makes playground rubber mulch a top choice for areas under swings and at the base of tall slides.
Should You Use Landscape Fabric Under Mulch? Here's What We've Seen Go Wrong. Landscape fabric under mulch may seem like a smart weed-control solution, but it often causes more harm than good. Over time, it blocks water and nutrients, damages roots, and traps decomposed mulch—leading to more weeds.
Yes, weed barrier fabric is recommended under loose materials like wood chips and rubber mulch. This helps prevent weeds and grass from growing up through the material.
Landscape fabric is typically used as a landscape management tool for the purpose of weed suppression and erosion control. It can do these things, but not as effectively as other organic mulches, and it usually causes secondary issues in the landscape through time.
Reader comment: "I am a huge fan of landscaping fabric for weed control. I have never noticed any adverse effect on the health of my succulents. In fact, the succulents in the area I covered with landscaping fabric (and rock cover) look better than those planted in soil with only rock cover.
Rubber mulch has a few downsides, including its high initial cost, flammability, and potential harm to humans or the environment.
Although sold as a solution to weeds, it often causes more harm than good. None are suitable for the health of the soil or the well-being of the plants it supposedly protects. This fabric blocks sunlight, impedes soil aeration, disrupts water infiltration, and prevents natural soil enrichment.

Seven Beginner Raised Bed Gardening Mistakes to Avoid
Yes, you should typically place soil on top of landscape fabric when making a raised garden bed or for landscaping. Landscape fabric helps to block weeds, retain moisture in the soil, and prevent soil erosion, but it is not meant to be the growing surface.
A place that landscape fabric is highly recommended is under non-decomposing products - such as river rock or rubber mulch. Those materials do not break down, therefore do not create a future problem. They actually help keep the landscape gravel from sinking into the soil and needing replenishment as often.
English Ivy is a plant that can remove 78% of airborne mold in 12 hours.
Rubber mulch is highly effective in deterring a wide range of pests commonly found in gardens and exteriors, including ants, termites, mice, and snails. This effectiveness stems from several key factors. First, rubber mulch does not serve as a food source for many pests like organic materials do.
