When it comes time to remove or reduce your lawn there are three standard methods to choose from. First you could remove the lawn manually with a sod cutter or sharp shovel. As you’ll notice I said the word ‘manually’ because it is just that- hard manual labor. Unless you are hiring a professional, the sod cutters for rent aren’t always that sharp and you need to have a lot of strength and push very hard to get results.
The second method, I don’t even like to mention, but unfortunately some landscape professions are still using a chemical kill. This means that they use toxic chemicals that are so strong, they not only kill your lawn but all the good organisms and healthy mycorrhiza that live in the soil. In short, don’t do it. It’s not worth your sacrificing the health your family and pets, yourself or your soil.
So that is why I started using the third method called sheet mulching or lasagna composting. Not only is it all organic but many of the ingredients can be obtained for little or no money. I also like this method because I am lazy. In other words, I can do this process once and it’s done and I don’t even have to break a real sweat!
With in one day with two people, we sheet mulched all 850 square feet of our front yard. As a homeowner, here are the steps I suggest you take:
- Rebate. Before you do anything to your alive, green lawn, check with your local municipal water department to see if you may qualify for a lawn removal rebate.
- Gather materials. You’ll need 3 basic items: manure or compost, cardboard and mulch. Click here to read more about where to find these materials.
- Prepare the site.
- Mow the lawn on the closest setting possible.
- Take a sharp shovel or pick and edge around any hardscape that the lawn comes into contact with. You can use this extra sod to make a berm (a raised area of earth).
- Remove any items that may get in the way like lights, drip irrigation tubing and rocks. Save any reusable items for later use
- Compost you lawn
- Lay out about 1-2 inches of compost or manure on top of lawn and water it in well
- Add a layer of cardboard and overlap each box about 25-50%. Designer tips: have the brown side up since it camouflages best with the wood mulch
- Add water again until the cardboard is soggy
- Add 2-3 inches of wood mulch
- Finished!
- Just remember to keep your new ‘compost area’ watered well. It should have the consistency of a damp sponge.
- In 3-6 months your lawn will be composted into the most gorgeous, friable, earth worm infested soil.
- Plant your new garden and enjoy.
Awesome! Thanks so much for sending this. This is definitely the step we’re going to take for three family gardens. Yahoo!

Julie: Thanks for shining a light on sheet mulching. You did a great job of explaining and documenting the process. The toughest part is always along the edges, where it’s hard to maintain enough thickness.
I’ll post a link to this blog at the Lawn Reform Coalition’s page at Facebook.

Julie, love this method. I’m wondering if you’ve done this in an area with existing trees. I would be concerned that tree roots might suffer from oxygen deprivation if they’re covered like this. Do you think it would endanger the trees if you covered a larger portion of their root system? I’ve got an small front yard with large trees that I want to convert to beds, and I’m struggling with how to get rid of turf + weedy green things without harming trees. Any thoughts would be appreciated.
Hi Shannon,
Since cardboard is a permeable (water and air can get through) material, no oxygen/carbon dioxide exchange should be lost. The whole purpose of the cardboard is to smoother the lawn or weeds from the sun and create a heat chamber (thanks to the manure) in order for composition to begin. Additionally, if you have an existing lawn tree, you most likely have a tree well of bender board around the base of the tree to protect the lawn from growing near the trunk. So, you’ll still be able to provide deep watering depending on the species and age of your tree. Good luck to you!
great work Julie, as usual!! we are hoping to convince more clients to use this method as it really is the least toxic and most beneficial way to eradicate turf or other low growing plants / groundcovers…keep us all in the loop w/ your progressive experimentation…thanks again!!
Hi Julie
Is this sheet mulching method good also if you are replacing an existing lawn with a new native sod grass lawn?as mentioned in your post here https://julieorrdesign.com/native-sod-grass-lawns
Hey Julie,
So excited to find this method and how you’ve detailed it. Thank you!
Would shredded fall leaves work in place of compost or manure?
Angela
Is it necessary to add the wood mulch on top of the cardboard or is that cosmetic?
Thank you.
True, it is partially cosmetic but it also adds organic matter and takes longer to break down than cardboard. Also, if you mulch, you could plant right away and no one would be the wiser that you are sheet mulching underneath!
I’m trying to decide the best way to deal with a “lawn” that came with the house we purchased last summer. It really isn’t lawn at all – it is a mix of 3-4 different invasive grasses and 2-3 very invasive weeds. None of it would be an acceptable “lawn”! I want to take it ALL out and eventually replace/replant as a cottage garden with some patches of no-mow grass. This organic method would definitely be my preference BUT I’m really concerned that I will just end up with crab grass and bermuda grass popping right up through it in a few months. That stuff never dies! What are your thoughts on the best way to approach this? Thanks so much!
Hi Emily,
The sheet mulching will work but you need to be prepared to do a bit of hand weeding for the first year. Also you may have to do a second layer like we did at our house on some of the more aggressive bermuda areas. It takes a lot of patience but so worth it and WAY better than harmful chemicals.
Good luck to you!
Hey Julie, I just wanted to give you an update! We did decide to “compost the lawn”, and although it was an incredible amount of work I’m so glad we did! We do indeed have some weeds popping up, but I use a tiny amount of chemical spray for the bermuda grass and hand weed the rest, and it is not a big problem. Overall the old lawn is now partially an in progress meadow and partially a cottage garden. I love it! The plants are really healthy, and there are worms and grubs crawling around in the soil everywhere. Thank you for the encouragement to go for it!
Fantastic news Emily! Thanks for the update.
Hi Julie,
What if your front yard is mostly dirt except in rainy season when it becomes weeds? Would you recommend sheet mulching before planting drought tolerant?
Yes, sheet mulch to protect from winter weeds.
