Intro
Mulch is a layer of material applied to the top of soil. This material can be something permanent like plastic sheeting,
or it can be something biodegradable, like most commonly, wood chips (source). There are many different reasons forĀ mulching. Most often, mulch is used as a weed barrier, to retain moisture, for the health of the soil, or even just for the visual appeal (source). However, before mulching it is important to note that mulch is not all good. The specific type of mulch you choose is specific to each situation. Some mulch can cause mold, diseases, and/or mushrooms (source).
How to Mulch
Experts recommend spreading mulch in the spring right after spring planting, though any time is fine. For organic mulch, it should be replaced when it has decomposed. For inorganic mulch, replace it every time it seems worn down or becomes ineffective. First, clean out the area you will be mulching. Remove any old mulch or organic debris. Also, remove any weeds you see. Now, smooth out the area to mulch. Next, put small mounds of mulch around your area. A big mound can result in too much mulch in one area, and can also damage small plants. Then, spread out the mulch to two to four inches thick. Also, mulch should be kept six inches back from trunks to avoid root and crown diseases. Water only lightly for the first 24 to 48 hours (source).
