I recently learned a simple trick to help keep plants free from weeds and soil-borne diseases, and believe it or not, it involves making lasagna! (Disclaimer: please do not try to eat this lasagna, because I don’t think it would taste very good!)
Making a “newspaper lasagna” using alternating layers of newspaper and dirt or mulch is an easy way to create a biodegradable barrier between your garden plants and any weeds or diseases that may come calling. It denies the bad stuff access to sunlight, yet allows rain and air to penetrate the soil.
It only takes a couple of minutes to put together, and you can plant as soon as it’s done! I’ve been wanting to put some thyme in my garden, so that’s what I’m showing here, but this would work just as well for flowers or veggies.
Start by scooping and inch or so of soil off of your area. Place about 10 sheets of newspaper over the area.
Once the newspaper is in place, soak the newspaper with water with a hose or a watering can, making sure to saturate it thoroughly.
Once the water has been absorbed by the paper, cover it with a layer of dirt or mulch.
Now repeat! :-) Place 10 more sheets of newspaper on the dirt, saturate it with water, then cover the wet paper with the dirt.
And that’s all there is to it! If you’re planning on planting in the area where your “newspaper lasagna” is, simply dig a hole with a trowel and place the plant right in. The soaked newspaper is easy to cut through.
You can also place create your “newspaper lasagna” between existing plants to help suppress weeds!
In addition to discouraging weeds, this gardening trick also helps conserve precious moisture, and as the paper decomposes, it will provide abundant food for worms and other soil-building friends.
Have you ever tried the newspaper lasagna gardening trick?
