The answer to 'DIY mulching' is that mulching your landscape can be a great DIY project that saves money and improves the health of your plants. Mulch is a protective layer of material, such as wood chips or shredded leaves, that is spread around the base of plants and trees. Applying a 2-4 inch layer of mulch helps retain moisture, suppress weeds, and insulate plant roots from temperature extremes.
To get started, first clear the area of any existing weeds or debris. Then spread the mulch evenly, taking care not to pile it directly against the stems or trunks of plants. Be sure to leave a few inches of space between the mulch and the base of the plant. Mulch should be replenished 1-2 times per year, typically in the spring and fall, to maintain the desired depth.
