Gardeners and landscaping experts have long utilized mulch to enhance the soil and make plants healthier.

Mulch, in its most basic form, is a layer of material placed on top of the soil. It may be applied for a variety of purposes, including boosting moisture levels or making the soil more productive.

If you’re new to gardening, though, you may not even know what mulch is. Mulch is simply any substance that may be spread over the soil’s surface. It is mostly used as a covering and for retaining soil moisture.

Mulch also helps to keep the soil cool and protects it from excessive frost throughout the winter months.

More significantly, mulch increases the garden bed’s visual appeal, making it seem much more appealing. Organic mulch, which is also widely available, may help to enhance the structure and drainage of the soil.

The soil’s nutrient retention capacity will improve as the mulch decomposes.

There are now various varieties of organic mulch available on the market. Before you decide to spread mulch on your soil, it’s a good idea to conduct some research to see what sort of mulch would be best.

The following are some of the most prevalent varieties of mulch available on the market:

  • Grass mulch
  • Newspaper
  • cuttings of grass
  • needles of pine
  • leaves shredded
  • Bark that’s been chipped or shredded

Organic mulch will decay over time and will need to be refilled. Its disintegration, on the other hand, will increase the soil structure and organic content.

The slower it decomposes, the drier it is and the more woody it is. It also gives the earth the least quantity of nutrients.

What About Mulch in Bags?

You may quickly scatter bagged mulch over your yard by purchasing it from your local gardening shop. Does mulch, on the other hand, go bad?

Yes, to put it simply. Mulch of all types will deteriorate over time and will need to be refilled. Because you can’t merely build on layers of mulch, it’s critical to remove the bottom layer after it’s entirely decomposed before adding another.

Bagged mulch is almost often offered in bags. It’s also known as bark since it’s quicker to transport and doesn’t need a wheelbarrow or even a shovel. The majority of people believe that bagged mulch never goes bad.

While bagged mulch may be kept for a much longer amount of time than typical mulch, it must be maintained properly.

First and foremost, make certain that the goods is well ventilated and dry. It’s much simpler to say than to accomplish.

Methods of Storage

If you purchase mulch in bulk, be sure to store it in a well-secluded location. Place a wide tarp behind the mulch bags and cover them with weed barrier fabric to keep moisture out.

More essential, spread the mulch pile out as far as possible to enable air to circulate around it and keep it adequately ventilated. This will prevent the bag from acquiring mold or mildew.

Mulch may also go bad if not properly applied. If you leave the mulch unmanaged, it has a good potential of causing major harm to the plants and trees in your yard. There are several telltale symptoms that your mulch is rotting.

Here’s what you should be on the lookout for.


You may witness mulch volcanoes forming around the tree’s base. This commonly occurs when heaps of mulch build up around the tree’s base.

Mulch surrounding the base of the tree, particularly in high amounts, may cause harm to the tree. Make sure there is at least four inches of mulch around the trunk.


There’s a risk you’ll wind up spreading water-repellent mulch all over your yard.

This is a major issue that occurs when mulch is left sitting for too long. If you don’t flip the mulch over and let it to sink, it will ultimately act as a protective covering for the soil, preventing even water from penetrating.

As you may expect, this is a severe issue. The mulch will prevent water from reaching the freshly planted plants and trees, causing them to soon wilt.

Due to decomposition, the woody mulch becomes rather heated throughout the summer months. This causes it to fully dry out. Fungi develops on top over time, hardening the mulch to the point that water runs off to the sides.

Keep an eye out for contaminated or unhealthy mulch as well. Invasive pests, fungi, or mold may form in the fungus, causing it to become unhealthy or infected.

You must keep a close look out for this and ensure that it is removed as soon as possible. Keep a watch out for artillery fungus or slime mold, since both may be quite dangerous.

Mulch is an excellent alternative for your soil and will only benefit your plants’ health. However, you must ensure that it is correctly layered and that it is not left neglected.

To get the most out of the mulch, you must flip it over on a regular basis, as previously stated. You will be able to detect when the mulch is going bad and take immediate action if you are cautious and continue to monitor it on a regular basis.
