It’s cost-effective.The simplest and most cost-effective product anyone can add to their garden is mulch; lots of it everywhere and apply it at least 2-4 inches thick over the entire bed. The cost is relatively low, but some sweat equity is required to install it.
It conserves moisture. With the moderate drought we’re in you don’t want to be out there watering all the time. There will probably be a ban soon anyway. Mulch reduces water runoff – which means the watering you’re doing is sinking in better than if it were bare soil. There is also a 10-25% reduction in soil moisture loss from evaporation with a 2-4 inch layer of mulch.
It saves you time. Although you can apply mulch any time of the year, the best time is late spring after the soil has warmed. Apply mulch in the Spring and weeds will have a tough time getting through during the rest of the year. No weeding, more time for you! Improves curb appeal. Curb appeal on your home will increase after mulching. The colors in your shrubs and plants will pop, and it gives your yard that “finished” look. Improves soil conditions. As the mulch breaks down it provides nutrients and aerates the soil.
The type of mulch you choose depends on your taste. Bark mulch is the cheapest and lasts the longest, but there are other options, including the black-looking, composted bark mulch, and wood chips.
