The answer to 'DIY mulch' is that mulching your landscaping is a great way to improve soil health, retain moisture, and suppress weeds. Applying a 2-4 inch layer of organic mulch around trees, shrubs, and garden beds is a simple DIY project that most homeowners can do themselves.
To get started, choose a high-quality mulch like wood chips, shredded bark, or pine needles. Spread the mulch evenly, keeping it a few inches away from plant stems and trunks. Be sure to replenish the mulch as needed, typically 1-2 times per year. Professional help may be required for large or complex landscaping projects.
