If there's one low-effort habit that transforms a garden, it's mulching. A layer of organic material on the soil surface holds moisture, smothers weeds, moderates temperature, and slowly feeds the soil as it breaks down. Here's how to do it right.
What mulch does
- ›Cuts watering needs by slowing evaporation.
- ›Blocks most weeds from germinating.
- ›Keeps soil cooler in summer and warmer in cold snaps.
- ›Feeds soil life and builds organic matter over time.
Good mulches for a vegetable garden
- ›Straw (not hay, which carries seeds) — classic for vegetable beds.
- ›Shredded leaves — free in fall and excellent.
- ›Grass clippings (thin layers, untreated) — nitrogen-rich.
- ›Wood chips — great for paths and perennials, less so tucked around annual veg.
- ›Compost — doubles as mulch and feeds directly.
How to apply it
Spread 2–4 inches over moist soil, keeping mulch an inch or two away from plant stems to prevent rot. Refresh as it breaks down. Weed first — mulch suppresses new weeds but won't kill established ones.
What to avoid
Skip hay (weed seeds), dyed or treated wood near food crops, and thick grass-clipping mats that go slimy. Keep it simple and organic.
Mulching pairs perfectly with a good watering plan to keep beds thriving between volunteer visits. Organize yours free with WeAllGarden. Get started.
