Inorganic mulches are the most durable, making them ideal for plants, beds, or permanent garden paths. Rubber and garden cloth don't break down like other types of mulch. Depending on the type of material and the watering program, the shelf life of the mulch may vary. Wood chips and bark mulch are the most common types of mulch.
They are more likely to break down than thicker materials. Wood chips can last between five and seven years. Bark mulch, on the other hand, can last seven to ten years. Because the bark consists of the hardest part of the tree, it is more durable than the waste material used for wood chips.
When comparing the two types of mulch, wood chips will last the longest. They contain a variety of materials of different sizes, making them more durable and resistant to compaction than other types of mulch. Wood chips contain different types of wood, bark, leaves and other materials that are useful to the plant. They are often used as mulch on trees and shrubs because they can help prevent erosion and prevent soil loss.
Shredded bark is one of the most common and least expensive types of mulch. It comes from a variety of sources, including cedars. Shredded bark is one of the best types of mulch for use on slopes and breaks down relatively slowly. As an added benefit, some crushed bark mulches are by-products of other industries and are considered environmentally friendly.
See the mulch packaging for more information. Natural materials such as bark or moss tend to last a short time. In many cases, you'll find yourself replacing these layers of mulch annually. While mulching may seem like a simple part of gardening, there are some facts you should know about the different mulches you can use and the benefits of each.
Organic mulches are good for soil fertility, but inorganic mulches have no nitrogen content and don't improve the soil beneath them. However, if you want more color to accentuate the colors of your plants and flowers, buy custom-colored organic mulches (such as the red-tinted mulch shown above). A layer of mulch can also help protect your garden from pests and weeds, but it's a good idea to follow guidelines for covering trees with mulch. Cedar mulch is also the most durable mulch, so you'll need to replace it fewer times than other mulches.
