Weeds…. they can be overwhelming this time of year due to spring rains and warming weather. Don’t despair! You can win the battle of the weeds without resorting to deadly chemicals or furious digging and yanking. A weed-fighting method called “sheet mulching” works in harmony with nature; weeds disappear while soil improves at the same time.
How does it work? The weeds are literally smothered and not allowed to see the light of day. Layers of compostable materials (such as newspaper or cardboard, compost and wood chips) are piled on top of the weeds. Then the naturally occurring microorganisms and worms in the soil below do the magical job decomposing the weeds.
With time, the mulch layers break down and provide organic material and nutrients to the soil. Thus, sheet mulching not only gets rid of weeds, it also improves the soil fertility and helps a happy community of earthworms keep the soil aerated.
In contrast, digging out weeds disrupts the soil’s natural ecosystem and destroys earthworm tunnels. Spraying with herbicides adds environmentally questionable chemicals to the garden. Sheet mulching works with nature rather than against it. […]
