How to Mulch
The first step to mulching properly is to select the mulch which best suits the needs of your landscape. Once you select your mulch type the amount of mulch youâll need will have to be calculated. There is also a specific technique for spreading mulch appropriately which involves slashing the bag while it lays flat on the ground rather than snipping the corner off and pouring it like cereal. If all these steps are carried out carefully and not haphazardly youâre almost guaranteed to have a successful mulching experience.

What Can Go Wrong
A primary concern of people who are thinking about mulching is what if the mulch goes âsourâ. This occurs when the mulch is not mixed properly and the lack of rotation of nitrogen causes pockets of increased decomposition. This causes the mulch to smell like vinegar or ammonia. If aired out properly, this processes usually reverses itself and is not a cause for concern. However, if the mulch is distributed without being aired out it will damage or even kill the plants in the area.
