    5. Tips for Using Mulch

What is Mulch?

Let’s start with the basics. What do we mean when we say mulch?

When we use the word mulch, we usually are referring to the typical crushed and composted bark that we put on our flowerbeds to control weeds and improve aesthetics. 

But mulch can include much more than that. 

By its basic definition, mulch is anything used to cover the ground to prevent weeds, enrich the soil, maintain temperature,  or prevent water evaporation or erosion.

So mulch can include anything from the typical bark mulch that most people think of when they hear the word to cardboard laid down to prevent weeds. It could also include straw, grass clippings, plastic, or composted leaves. 

As you can see, it can cover a lot! (no pun intended:))

Now that we know more about what we mean when we say mulch, let’s take a look at some different types of mulch and their uses.

Types of Mulch

Different types of mulch are used for various purposes. 

Some types of mulch specialize in enriching the soil or aiding in water retention. Others are better for weed control or simply exhibit better aesthetics. 

Mulch comes in two basic categories: Organic and Inorganic. 

Organic mulch is made from organic materials like bark or straw and is biodegradable. These mulches improve soil nutrients, aeration, and drainage. However, because they biodegrade, they need to be replenished regularly.  

Inorganic mulch is made from non-biodegradable materials such as plastic, rubber, or stone. Inorganic mulches are superb weed control products and usually improve aesthetics, but they do not provide any enrichment for the soil. 

Let’s look at the different products available within each broader category.

Types of Organic Mulch

Bark Mulch

Bark mulch is made of shredded tree bark aged to a deep brown color. 

Note: Since aged mulch is more composted than fresh mulch, it is better for new plants that need lots of nutrients right now. Fresh mulch, by contrast, takes longer to decompose. This means, of course, that it lasts longer than aged mulch, but its soil-enrichment properties are not nearly as high at the time of application. Always keep the age of your plants in mind when choosing between fresh or aged mulch.

Because bark mulch is made of the tree’s outer bark instead of its hard inner wood, it decomposes quickly making it one of the best mulches for adding nutrients to the soil. It’s also great for moisture retention.

The texture of bark mulch varies with different manufacturers. In general, the finer the texture, the better the mulch is for the soil. 

At Zimmerman Mulch, we make our premium bark mulch out of nearly 100% hardwood tree bark and age it for a year. Our bark mulch comes undyed in its rich, natural, brown color. 

Hardwood Mulch 

Hardwood mulch is similar to bark mulch, but it contains a mixture of both tree bark and shredded hardwood. Because it contains hardwood, this mixture usually needs to be double ground to achieve the desired finer texture. It is then screened to filter out any remaining sticks or chunks of wood. Hardwood mulch is sometimes aged before sale and at other times is sold fresh. It ages to a similar deep brown color as our premium bark mulch.

Hardwood mulch decomposes much more slowly than bark mulch. This means, of course, that it lasts longer as mulch but doesn’t add as many nutrients to the soil.

At Zimmerman Mulch, we produce fine, double-ground hardwood mulch made from fresh, clean wood. Unlike other companies, our hardwood mulch contains very little pallet wood (a filler used to stretch mulch), which results in a much cleaner product. Our Nature Blend Mulch is another mulch which is aged to a dark color and works well on general landscapes, woodland borders, or trail surfaces. 

Our hardwood mulch also comes dyed in several rich colors. 

Color-Dyed Mulch

If you would like a different color than the traditional dark brown mulch, or if you would like a mulch that retains its hues longer, color-dyed mulch could be a good option. 

Color-dyed mulch is dyed to prevent fading. Undyed mulches may fade to gray within a month or two, but dyed mulches can retain their vibrancy for over a year.

Dyed mulch comes in colors including brown, black, and shades of red. You can select the color that best complements your house and landscaping. 

At Zimmerman Mulch, we carry several shades of color-dyed mulch, including Colonial Black hardwood mulch, Coffee Brown hardwood mulch, and Beauty Bark mulch, as well as traditional aged bark mulch.  

Playground Mulch 

If you need to cover large areas with mulch to keep down weeds and improve aesthetics, playground mulch might be your best option. 

Playground mulch is made of bark and hardwood but is not as finely ground as other mulches. It consists of larger pieces of fresh wood that don’t decompose quickly.  

Since playground mulch is cheaper than most other types of mulch, it is a good option for covering large spaces such as pathways or play areas. It keeps down weeds, defines spaces, and provides excellent shock absorption. 

Zimmerman Mulch provides quality, durable, Playground Cover for recreational spaces. It is perfect for playground areas, walking trails, and even dog kennels. Our Playground Cover is IPEMA Certified, so you can enjoy the peace of mind that you are getting the best possible product for your playground area. 

Mushroom Mulch

Mushroom mulch is an incredibly rich mixture of straw, animal manure, and other organic materials. Mushroom growers have developed this mixture in which to grow their mushrooms, and when it’s no longer suitable for this, they sell it as mulch. 

This type of mulch provides an abundance of great nutrients for the soil, holds moisture well, and decomposes quickly. 

You can use it as a nutrient-rich mulch for your flowerbeds, sprinkle it on your yard as a fertilizer, or mix it into the soil in your vegetable garden or flower pots.  

However, we don’t recommend using mushroom mulch around trees or shrubs as it holds water and tends to remain damp. The moisture attracts insects and diseases which can hurt the trunks or stems of the plants. Mushroom soil tends to be more alkaline, so it should not be used extensively around acid-loving plants such as shrubs and evergreens.

At Zimmerman Mulch, we sell a mushroom mulch made of straw, horse manure, and other organic materials which will provide significant benefits to your lawn or flower beds.

Wood Chips

Wood chips are simply chips of hardwood. Wood chips are similar to playground mulch but typically are much larger chunks. 

Since they are made entirely from hardwood and are not aged, they last for a long time before they decompose. This means you won’t have to reapply them very often. 

Wood chips are usually cheaper because they are readily available and don’t require as much processing. This makes them a good choice for covering large areas such as fire rings, picnic areas, or walking trails. 

Wood chips are not a great option for flower beds as you have probably guessed. In fact, they actually pull water and nutrients from the soil, depriving your plants of the nourishment they need instead of adding anything to soil fertility.

For best weed control in large areas, we recommend putting down a layer of plastic or landscaping fabric as a barrier, then layering wood chips on top for an attractive appearance.

Zimmerman Mulch carries clean, quality hardwood chips in a light to medium brown color.  

DIY Mulch Options 

Mulch doesn’t have to be complicated! 

You can use your grass clippings as mulch for your flowerbeds. Grass clippings help conserve moisture and add nutrients to the soil. However, at some stages of composting, grass clippings can be very acidic and can contain residual lawn treatment chemicals.

Straw and hay are also great options for mulching your flower beds, garden, or newly planted grass. 

Other DIY options you could try:

As you can see, there are lots of options in the organic mulch category. 

Now let’s look at some of the inorganic types of mulch. 

6 types of organic mulch

Inorganic Mulches

Inorganic mulches do not enrich the soil or add any nutrients to it. In some cases, they may even prevent nutrients from reaching the soil. But they usually improve the aesthetics of a landscape and aid in weed control. 

Inorganic mulches may cost more initially than organic mulches, but they are often more cost-effective because they do not need repeated reapplication. 

Here are some common options for inorganic mulches. 

Chipped Rubber 

Chipped rubber is usually made from old tires that have been ground up into bits. 

The benefits of using chipped rubber over wood chips are that the rubber will not rot, compact, dry up, or hold moisture, and will last for years without replacement.

Rubber chips also provide excellent shock absorption, making them a good option for playground areas. 

Rubber chips work well for covering any large area since they keep down weeds and provide a clean walking surface. They can even be dyed a variety of colors for added attractiveness.


Did you know you can use gravel as mulch on your flower beds? 

There are several benefits to using gravel as mulch. It will keep down the weeds without rotting, easily washing away or compacting, and it can last for years without replacement.  

And for some people, gravel provides the exact look that they desire for their landscaping.

However, gravel will not benefit your soil in any way and is not a great option for moisture retention. It is also not very comfortable to walk on with bare feet. 

If you need gravel, we have an excellent selection of gravel and stone at Zimmerman Mulch! Give us a call today

Landscaping Fabric 

Landscaping fabric technically falls under the category of mulch as well because it serves to keep weeds down. 

Landscaping fabric acts as a barrier against weeds while still allowing water and air to circulate. You can layer gravel, traditional mulch, or other landscaping materials on top of landscaping fabric to create an attractive appearance.

If you are seeking a cheaper option, you can always choose plastic instead. However, since plastic will not allow air and water to enter the soil, it is not a good long-term option.

Now for the bonus! 

Let’s look at some helpful tips for using traditional mulch. 

Tips for Applying Mulch

Here are some professional tips to make your mulching painless and effective: 


  • Mulch in the Spring and Fall for best results. 
  • If  your mulch is delivered in bulk, lay down a tarp to dump it on. This makes for easy cleanup! 
  • Don’t spread your mulch too thickly or too thinly. If you are starting a new mulch bed, 4” is a good depth. If you are reapplying over old mulch, 3” is enough.
  • If there is a thick layer of old mulch in the bed, remove it or rough it up before adding new mulch over it.
  • Wear gloves. Color-dyed mulch can stain your skin and nails. 
  • Distribute the mulch evenly. This makes your flower beds much more attractive. 
  • Make basins around trees and bushes instead of piling the mulch around the trunks or stems. A basin captures needed water for the plant instead of letting it run off and keeps the mulch from smothering and damaging the plant stem.  
  • Make sure all leaves and plants are free of mulch before you finish.
  • Use a garden rake to distribute mulch evenly. 
  • Spread color-dyed mulch when the weather is dry. The colors in dyed mulch can bleed onto concrete walkways or driveways if the mulch becomes wet before it has time for an initial dryout in your landscaping. 

Congratulations! Now you understand the different types of mulch and their best uses. Our hope is that this proves helpful the next time you prepare to mulch your flower beds.
