Additionally, they dry so fast in case of a downpour, and they don’t freeze even in cold weather, making them fit for playgrounds in all seasons.

  • Control growth of weeds: The rubber weed barrier blocks the sunlight that weeds need to grow. It suppresses their development; this saves you time and energy to uproot or spray these weeds.

What I Like

  • Light and allows water flow: Pine straw mulch is very light and easy to spread. It also lets water through it very well to your plants.

You don’t need herbicides to control weeds in your garden anymore; the plastic sheeting roll sorts you out. It primarily eliminates the growth of weeds.

The plastic mulch is impermeable and protects the exchange of air, nutrients, and water from the surrounding. It also blocks sunlight, and through all this, the weeds cannot survive. 

Again, it retains the soil moisture and warms the soil up. Warming may affect your plants in warm areas by causing the roots to rot, so use it with caution.

Note that this type of mulching is only suitable for a short period.

Factors to Consider When Buying Black Mulch

It’s clear from the above-detailed outline that black mulch is available in various styles, sizes, and types. What factors should you consider before settling for the best black mulch for your lawn, therefore?

  1. Intended Use

The primary thing to consider is the intended use of the black mulch. All the black mulch discussed above can suppress weeds and control moisture. 

Your choice depends on your usage. 

For decorative purposes, rubber mulches are best. While for gardening, you can use others, including fabric and plastic mulch.

  1. Durability

Purchase the mulch that lasts you long before replacing it. In the case of fabric mulch, you can put a layer of other decorative mulch to make it stay longer. 

  1. Location

Make sure you choose the best black mulch depending on the weather around your area as it affects its longevity. Buy UV-resistant mulch if your region has much sunlight. The same goes for moisture retention. In the wet part, avoid plastic weed barriers as it causes the plants to rot.

  1. Ease of Installation

Select a black mulch that is effortless to install. All the above mulches have easy installation and will save you time.

  1. Composition

Focus on the type; the black organic mulch decomposes with time, releasing nutrients into the soil. On the other hand, the inorganic doesn’t decompose but, it’s durable. 

You can choose the one that suits your needs from the various options.


a. What Type of Black Mulch is Best? 

My best black mulch is the Longleaf Pine Straw because it’s organic and its low breakdown speed is a plus since it stays long before replacing it. Besides, it’s readily available and affordable, too. 

But the fact that, as it decomposes, it releases nutrients into the soil, making it even healthier, assures me of my great choice.

Black mulch is of good quality. Nevertheless, the best depends on your preferences. My choice for aesthetics is Plow and Hearth rubber mulch for its thick, porous, and durable mulch.

b. Does Color Mulch Fade?

Yes, but the extent to which your mulch fades depends on maintenance, rain, sunlight exposure, and general weathering. 

However, it’s important to note that dyed mulch takes much longer to fade, actually a year or longer than naturally colored mulch. 

You need to maintain the color by adding a fresh layer over the existing one from time to time. Even so, examine the existing color mulch before adding more.

c. What is the Darkest Mulch?

The Goasis Lawn Weed Barrier is the darkest mulch; it creates a great contrast in your garden and appeals to the eyes. It’s a long-lasting mulch that suppresses weeds, and it doesn’t quickly fade. Since its UV resistance, it maintains its black color for so long. 

It’s safe, non-toxic, and gives your landscape a pop of color. 

The color adds nothing to the soil apart from the aesthetic value. The Goasis weed barrier retains the soil moisture while protecting the weeds from germinating.

d. Does Mulching Grass Using Black Mulch Increase its Growth Rate? 

No guarantee that using black mulch increases the grass growth rate. However, it’s beneficial to the soil on the beds as it adds up nutrients after decomposing. 

It suppresses the growth of weeds, retains the soil moisture, and reduces soil erosion during heavy rains. All this, in return, enhances the development of healthy grass. 

Also, it retains moisture during summer and maintains cooler temperatures that keep the grass vibrant.

Mulching the grass beds also saves you time as maintenance is low.

Parting Point

Adding black mulch to your garden, base of plants, or on your children’s playground is an attractive and beneficial touch-up. But, what is the best black mulch? 

Note that all the above reviewed black mulches are safe, help suppress weeds’ growth, and help to retain the soil moisture. However, your preference and where you need to use it determines your choice. 

For instance, if you need something that adds nutrients to your flower garden, go for the Longleaf pine straw mulch and not the rubber nuggets. Finally, ensure you buy the type that fits your purpose and suits your budget.
