If you are planning to swap out grass for a water-wise yard, now is a great time to begin. While fall is often ideal because rains keep the sheet mulched area moist, late winter and early spring still work very well in our climate, although you may need to water. Getting started now gives your soil time to improve before peak planting season, so when you are ready to plant, the groundwork is already done.
What is sheet mulching?
Sheet mulching, also known as lasagna mulching, is a simple, natural way to remove grass without heavy digging or chemicals. You place cardboard over your lawn, add compost on top, then cover everything with a layer of mulch. Over the next few months, the grass underneath breaks down and feeds the soil. Cooler temperatures and natural soil moisture from rain help the process along, making this season a solid choice.
How sheet mulching works
Sheet mulching removes lawn naturally while improving soil health. Mulch sits on top. Cardboard blocks sunlight and suppresses weeds. Compost adds nutrients. The grass underneath breaks down and feeds the native soil, while worms and microbes build healthier ground for planting.
Why choose this approach
You could tear everything out with equipment and haul it away. That may feel faster, but it also strips away organic material and can disturb healthy soil. Sheet mulching works with the soil instead of against it.
“Sheet mulching builds the soil while it removes the lawn,” said Bobby Alvarez, water conservation administrator. “Instead of starting from scratch, you’re improving what’s already there and creating a healthier foundation that will need less water long term.”
What to expect
Plan on waiting about two to four months before planting directly into the area. If you need to plant sooner, you can cut small openings into the sheet mulch and plant through it.
It’s a simple first step toward creating a yard that works with our climate, holds moisture more efficiently, and reduces the amount of water it needs, giving water back instead of constantly demanding more.
