There are many benefits of rubber mulch for your lawn and garden, but the downsides are many as well. Here are some of the downsides: Cost, Lifespan, and Metal Toxicity.

Read on to find out the truth about rubber mulch. Just remember, quality doesn’t come cheap. Rubber mulch is the best way to protect your lawn and garden from invasive weeds and pests.

Disadvantages of rubber mulch

While many people love the environmentally friendly and cost-effective benefits of rubber mulch, there are several drawbacks. These include flammability concerns and a relatively high initial cost. Furthermore, rubber mulch is difficult to remove from the ground, which makes it more expensive than other types of mulch. Rubber mulch also lacks organic material and does not decompose easily. This makes it less ideal for flower beds and vegetables, and its chemical residues are harmful to plants.

In addition to being a fire hazard, rubber mulch is inherently unappealing to most pests. Asian cockroaches and their babies are particularly attracted to rubber mulch. The mulch is also inorganic, meaning it does not absorb water. It also cannot be destroyed by fungi or mold, but it can ignite a tire-like fire, which is difficult to put out.

Rubber mulch is expensive and contains toxins. Some types contain carcinogenic substances, such as zinc oxide. While these compounds leach out with time, they remain harmful for plants. However, the risks are small compared to the potential health consequences. If you’re growing plants in hot climates, you’d be better off with other materials. And remember: if you’re going to use rubber mulch, make sure it’s made from recycled material.


The initial cost of rubber mulch is about $5-$7 per cubic foot, depending on the type of material used. For example, a playground that is 6,000 square feet will need approximately 5,000 cubic feet of rubber mulch surfacing. With this cost, rubber mulch can easily run into the tens of thousands of dollars. However, once installed, rubber mulch will be very low maintenance, as the material doesn’t need to be replaced as frequently.

Rubber mulch is a great upgrade from Engineered Wood Fiber. It won’t compact, decompose, attract animals, or attract insects. And it won’t need replenishing. Rubber mulch is produced from recycled tires, making it a good solution to the growing concern over the disposal of used tires. These tires are stripped of their steel by mechanical means, and the metal is scanned with powerful magnets to identify any loose metal.

The report also covers the competitive landscape in the Rubber Mulch market. The report provides a comprehensive analysis of major players, their product lines, and their market revenues. The research also includes their manufacturing processes and gross margins. And, it also includes an overview of each region’s market for Rubber Mulch. This information will help market players decide the most appropriate growth strategies to maximize profits. The Global Rubber Mulch Market is projected to grow at a CAGR of 6.8% from 2017 to 2029.


While rubber mulch does help to slow weed growth, it cannot be tilled into the ground. That means you have to manually weed the area once it has been mulched. The product also doesn’t provide any soil nutrients. Because of its low water-holding capacity, it is not ideal for organic gardening. It also requires manual removal. Moreover, it is more expensive than organic mulches. In addition, it has a shorter life span than many other mulch products.

While wood chip mulch may look good on the surface, it degrades over time, requiring constant replacement. Another drawback of wood chip mulch is its poor drainage. On the other hand, rubber mulch has a very long life span because it is made of shredded tires. Tires can last for tens of thousands of miles or up to six years. Rubber mulch is a great option for playgrounds. If you are concerned about safety, rubber mulch may not be the best choice.

Once installed, rubber mulch can last for years if properly cleaned. Regularly cleaning the mulch will keep it looking new and hygienic. It is also easy to clean up pet poop. But remember that the pile of leaves is a fire hazard and can be easily ignited. As it is heavy, you should use a blower to clean up leaves and other debris. However, make sure to use several angles when cleaning the mulch.

Metal toxicity

Many people wonder if using rubber mulch is safe for plants. Although rubber mulch adds no nutrients to the soil, it can clog the pores, preventing water, air, and nutrients from reaching the roots of plants. The resulting shallow rooting may lead to plant death. Rubber mulch can also accumulate heavy metals like zinc, which can negatively affect the health of plants in acidic soils. The following information can help you decide whether or not rubber mulch is safe for your plants.

The main disadvantage of recycled rubber mulch is that it is difficult to remove once it has been applied. The resulting soil will be contaminated with toxic metals and other harmful chemicals. Additionally, some varieties of recycled rubber mulch may leach toxic chemicals. Rubber mulch can also be flammable, producing fumes that resemble those produced by tire fires. The material is also difficult to contain and can migrate into waterways. However, recycling rubber mulch has some benefits.

A study conducted at Yale University found that playground rubber mulch contains high levels of 12 carcinogens and heavy metals. Some of these substances are found in rubber tires, which are already toxic to humans. Further, the research team also discovered that rubber mulch is a source of many toxic substances, including lead, zinc, and cadmium. These substances can cause gastrointestinal and reproductive problems. Further, exposure to roadway contaminants can pose a potential liability for playground institutions.


If you are looking for a playground surfacing that is safe for children, rubber mulch is a great option. Its durability and shock absorbing capacity make it a popular choice. The highest fall rating among playground surfacing materials is ascribed to rubber mulch. Aside from being safe, rubber mulch can also be recycled. In playgrounds, 6 inches of rubber mulch will protect a child from 10 feet of impact. It’s recommended to install this mulch at least six inches deep.

The advantage of rubber mulch over other mulch products is its low maintenance. It doesn’t need to be raked or trimmed, unlike most organic mulches. Rubber mulch is also not susceptible to fading, so it can stay in place year after year without needing to be replaced every few years. This can save you money and time since you won’t need to replace the mulch every year. It also has the added advantage of being visually appealing.

Another drawback of rubber mulch is that it can leach heavy metals into groundwater. Because it contains a high level of zinc oxide, this metal can accumulate in plants. This is especially harmful in soils high in zinc. For this reason, it’s important to choose a rubber mulch with an environmentally friendly policy. There are several ways to recycle tires in your yard. Just make sure to follow all the manufacturer’s recommendations.


When choosing the color of rubber mulch, you’ll need to think about the area in which you’ll use the mulch. Most rubber mulch is brown, black, or red. You can also select an uncoated color. If you’d like your mulch a different color, contact a rubber mulch supplier for a custom order. Custom colors may be more expensive than standard options, but are well worth it if the mulch will help you create a more aesthetically appealing landscape.

Another benefit of rubber mulch is that it is very low-maintenance. Most brands will last 10 years or longer without needing to be replaced every year. Unlike wood mulch, rubber mulch allows water to filter through. It also keeps the soil moist and warm. It doesn’t attract certain pests like ants and spider mites. Because it doesn’t need to be replaced annually, the color won’t fade.

Another benefit of rubber mulch is its ability to keep the soil cooler while absorbing heat from the sun. While wood chips, pine straw, and other lightweight organic mulches float and drift in water, rubber mulch will stay put and not move in a flood. It can also be blown away by strong winds or leaf blowers. So if you don’t want to deal with cleanup after a flood, you should consider rubber mulch.
