Before considering when to mulch a garden, it’s important to understand what mulch is, and why gardeners use it in the first place.
This makes it easier to understand which type of mulch is most appropriate to use alongside your plants.
Mulch is a top-layer gardening material that is spread over the ground surrounding plants. Depending on the type of mulch used various levels of water, light, and nutrients are filtered through the earth to the plants’ roots. Mulch also traps moisture in the soil, and can act as a sort of shield against environmental hazards to plants. These hazards include direct sunlight, harsh winds, and frost.
