Is Colored Mulch Toxic?

In the garden, there are many questions related to colored mulches.

Is it toxic or not? What kind of health risks does it pose? Can I use it safely in my garden?

These are some of the most common questions which arise from using colored mulches. Let’s look at these issues one by one:

Are Colored Mulches Toxicity Safe For Dogs And Cats ?

Colored mulches are generally considered safe for dogs and cats. However, they may present different kinds of health concerns when used in small quantities. So, it is better to avoid using them in your garden if possible. If you have any doubts about their safety for pets, then you can always ask your veterinarian before using them in the garden.

What Kind Of Health Risks Does Colored Mulch Present?

Dyed mulches contain various substances such as silica, iron oxide, and other minerals. They are usually made up of several ingredients. Some of these ingredients may cause allergic reactions in humans and animals. Other harmful substances include lead, cadmium, arsenic, boron nitride (BNN), chromium oxide (CrO2), copper sulfate (CuSO4) and others. All of these materials can cause cancer in humans and animals. They can also cause respiratory problems and other health concerns. So it is better to avoid using these dyed mulches if possible. You can always opt for a safe alternative such as a plain natural mulch, gravel or nothing at all.

What Are The Alternatives To Colored Mulches?

The most obvious choice would be plain natural mulch (e.g. pine bark, pine straw, wood chips, etc. made from a natural material). If you want to add a splash of color, consider using plain white gravel or some colorful rock instead. Or you can leave the soil completely bare. It’s up to you and your tastes.

Is Colored Mulch Safe For Dogs And Cats?

Yes, colored mulches are generally safe for dogs and cats. They are non-toxic (although there is always a small risk of an allergic reaction). Sometimes animals like to consume mulches. This can be harmful if large quantities are eaten. But this is usually not a problem if the mulch is used in reasonable quantities in your garden.

Is Colored Mulch Safe For Horses?

Colored mulches can be safely used for horses subject to the following conditions:

The horse should not be allowed to eat large quantities of the colored mulch (as per general rule).

The colored mulch should not contain a large quantity of copper sulfate (CuSO4) or any other poisonous materials.

Some colored mulches may stain the horse’s skin and/or coat.

Is Black Decorative Mulch Safe For Dogs And Cats?

As mentioned above, colored mulches are generally non-toxic. However, black decorative mulch may contain lead which is toxic to humans and animals. Ingesting large quantities can cause lead poisoning. Lead poisoning can cause serious damage to various organs such as the brain and the kidneys. In severe cases, it can be fatal.

In addition, decorative mulches in general have been known to cause intestinal obstruction in dogs and cats if ingested. This is due to the stringy nature of some mulches (e.g. shredded bark) which may become knotted inside the intestines causing a blockage.

So it is recommended to keep all mulches out of the reach of dogs and cats for their own safety.

Is Colored Decorative Landscape Gravel Safe For Dogs And Cats?

As mentioned above colored decorative landscape gravel should not be allowed to be ingested. Most decorative landscape gravels are quite rough and may cause a lot of damage when they are swallowed. A reasonably large stone might not cause that much harm if it becomes stuck in the intestines. However, decorative landscape gravels tend to be very small and very smooth. These small smooth gravels can cause very serious and life threatening damage if they become stuck in the intestines.

If your pet does happen to swallow some decorative gravel there is a possibility that an intestinal obstruction may occur. This is a true medical emergency which may require surgical intervention to remove the gravel from the intestines.

So it is recommended to keep all decorative gravels out of the reach of dogs and cats for their own safety.

What Is Black Stain?

Black stain is a substance used to darken and color concrete or soil. Sometimes it is also called “Black Beauty Sealer” or “Concrete Sealer”. Black stain contains asphalt which is a naturally occurring substance found in rocks and soil. Asphalt is usually black or dark brown in color. Asphalt has been used in various applications for many years such as road paving, roofing, waterproofing, etc.

Black stain can be advertised as pet friendly if it does not contain any volatile organic compounds (VOCs). Most of the time black stain is compatible with pets but it may clog the animal’s pores and fur which could lead to skin irritation, rashes, or other allergic reactions in some animals.

The primary danger of black stain is similar to colored mulches. Ingesting large quantities can cause intestinal blockages. This is not likely to happen with most pets, but if you have a large outdoor dog or cat who is prone to eating things they shouldn’t and they consume a large amount of black stained concrete, it is possible that some obstruction may occur.

It should also be noted that tar based sealers can be quite slippery. If you have a pet who likes to walk on freshly black stained asphalt then they could be injured if they slip and fall. This is not likely, but worth mentioning.

If You Choose To Use A Non-Pet Friendly Product

If you choose to use a non-pet friendly product in your landscape and you have pets, it is recommended that you place fresh dirt in areas your pets have access to. Solid sealed concrete or large expanses of mulch can become quite slippery when wet, so it is always a good idea to keep your pet’s paws in dirt rather than mulch or wet concrete.

Hopefully this article has shed some light on pet friendly landscaping materials and you can make an informed decision on what to use in your own landscape.

Is Colored Mulch Safe For Kids?

Mulch is fantastic for your landscape. It saves time and money, and it makes your yard look better than ever. But there are many types of mulches out there and some may not be safe for children to play on or near.

Children can easily get mulch all over their hands and then put them in their mouths. This can be a problem because some types of mulch can cause serious illness if ingested. It is important to keep your children safe from contaminated mulch.

So what kinds of mulches are toxic to children?

Garden center mulches: Most mulches sold at the garden center, especially the brightly colored ones are treated with chemicals and dyes in order to enhance their appearance. While many of these dyes are harmless, some of them contain high levels of lead. Lead is a poisonous metal that can cause serious illness and brain damage in young children.

Wood mulches: If you use wood mulch, there is a chance it was treated with the poisonous pesticide pentachlorophenol (PCP). This chemical has been banned in many states and can cause serious damage to young children. It is important that you don’t use wood mulch if it is from a unidentified source.

Organic mulches: While most organic mulches are safe, there is one type that you should avoid using in your landscape. This is shredded bark. Since shredded bark resembles candy, many people use it as a decorative filler for birthday parties. Children may eat the mulch thinking that it is candy and this can cause several health problems.

It should also be noted that some safe mulches, such as clay based ones have a higher level of dust. This dust can irritate children’s eyes and lungs. It is best to keep children away from these types of mulches until they have had a chance to settle.

As you can see, mulch can be dangerous to children if not used properly. If you are a parent, it is important to keep your children safe from mulch. One easy way to do this is by using decorative gravel instead of mulch. Gravel doesn’t have the same allure that mulch does and therefore is less likely to be ingested or played in.

If you must use mulch, make sure it is a type that is safe for children. Stay away from the brightly colored ones as these are most likely to be treated with dyes and chemicals. Confirm that the source of your mulch is reliable and trustworthy. Ask if the mulch has been treated with any poison pesticides or herbicides.

Finally, always supervise your children when they are in the landscape. Even if you use safe mulch, a child will find trouble if they are allowed to play unsupervised.

Mulch has many benefits for your landscape, but it can also be dangerous. Be careful when choosing and using mulch in order to ensure that you and your children stay safe.
