Sure, adding mulch to your garden and landscape makes your plantings look terrific (and can even add a beautiful swath of color), but it also accomplishes many great things for both plants and soil. Here's why mulch could be considered a gardener's best friend:
You'll have to do less weeding. When you cover soil with mulch, sunlight can't reach weed seeds, so many won't germinate. Weeds that blow in and settle in the mulch may sprout, but they will be much easier to pull.
You won't need to water as much. A layer of garden mulch helps soil retain moisture longer, because the sun's warmth won't bake the top layers of soil. When rain comes, that same mulch layer helps slow storm water run-off, so more rain soaks into the soil. Garden mulch also helps prevent soil compaction during downpours, keeping soil light and fluffy, which is a key to healthy root systems.
Your plants get some disease-fighting help. Many plant diseases begin in the soil and spread to plants through splashing raindrops. A mulch layer acts as a buffer between soil and plant leaves to help prevent disease spread. Plus, it can keep crops like lettuce, leafy greens, and cabbage cleaner (less work for you at harvest time!).
Your plants stay warmer. In cold weather regions, garden mulch protects plants against winter chill and frost heave, which occurs when soil freezes and thaws. A frost heave can push perennial crowns out of the soil and expose them to killing temperatures.
When it comes to types of mulch, you have lots of choices. Scotts® bagged mulch is convenient, easy to use, and comes in a range of colors for your landscape.
