    Perth Experts Share Some Significant Info About Mulches


    Mulch is any type of material which is laid over or spread over the surface of the soil. It is mainly used to retain moisture in the soil, to keep the soil cool, to make the garden bed look very attractive, as well as to prevent weed growth. Organic mulches likewise help in improving the soil’s fertility since they decompose.

    Different Organic Mulches And Their Uses

    Grass Clippings – These are a mixed bag and are perfectly suited to the remote areas of your garden where you want to prevent weed growth. Grass clippings decompose rapidly. In the process, they can get somewhat slimy. Also, they tend to mat down and prevent water from passing through. Ideally, the grass clippings must be left on the lawn to add fertility to that soil.

    Compost and Composted Manure – They can be used almost anywhere, as long as they are well-composted and weed-free. You can actually use them as a coating of mulch in order to insulate and give a boost of slow released nutrients.

    Bark Mulches – These are best used around shrubs, trees, and in garden beds where you won’t be digging a lot. These mulches do not mix into the soil and it can be a hassle to have kept moving them aside in order to make way for growing plants. Remember though that some bark mulches might be toxic to young plants. Toxins can actually be leached from barks by heavy watering or evaporated through aeration. Some of the most desirable characteristics of these mulches are their excellent resistance to compaction, and their attractiveness.

    Shredded Leaves – These are natures’ favorite mulch. They can be used as mulch to almost anywhere. Another important thing about this mulch is that it is free. Shredded leaves are usually used as summer mulch. But when these leaves are not shredded finely, the leaves tend to mat together. Also, it might form a barrier that will block oxygen and water movement into the soil. To get excellent results, you have to allow the leaves to partially rot prior to using them as mulch. They’ll finish decomposing in place, thereby contributing nitrogen, humus and other nutrients to the soil.

    Pine Needles – These have a pleasing appearance. They are not usually for sale; however, it can be raked up from around pine trees. Pine needles decompose slowly, are very easy to work with, and are very resistant to compaction. Indeed, they can provide excellent protection around young ornamental plants.
