Preparing a garden bed with cardboard makes that ideal environment for the plants you intend to grow. The cardboard traps warmth and retains moisture in the soil, and forces any existing seeds to germinate. At the same time, the cardboard blocks out any light to the sprouted seeds causing them to die.
Layer 3 to 4 inches of compost on top of the cardboard. Water the compost well. Cover the space with garden sheeting to keep the soil in place and weeds from sprouting. In about 6 months, the cardboard will have broken down, and the space will be ready for planting.
Your first alternative weed barrier is something you probably have loads of laying around your house. Every time you make an online purchase, you get a cardboard box! They are usable as a plant-friendly, biodegradable landscape fabric alternative.
Though termites can eat some types of wood, they prefer cardboard in taste testing. If they are given no choice and have only wood to eat, they will consume it but their survival rate decreases.
A layer of cardboard left in place for a season smothers out grass and weeds, creating a ready-made garden plot, no tilling required. It's free, and you can feel great about reusing a product that would otherwise go to waste.
Add 4 - 6” of soil or compost or mulch on top of newspaper/cardboard layers 6. Allow 6 - 8 weeks for the grass under the paper/cardboard & compost layers to die back. Be patient! The longer you allow the decomposition process to take place, the better results you will see.
Container Garden: Yes!
You can plant into cardboard boxes and use them as your containers! Remember, they decompose in about 3 months which is the lifespan of a lot of vegetables. If you find that it decomposes quicker than your plant's life, try adding it to another box!
Because biodegradable fibers break down easily, roots can push through the sides of the cardboard as they grow.
It's the same steps used for preparing open, in-ground garden beds. Line the bed with plain cardboard, dampen it, add 6-inches (or more) of good quality soil, compost, or other organic mulch. Several months later when the cardboard has rotted and the grass below is gone, it's planting time.
Make sure to rake away rocks or other debris from the site, break up large clods of dirt, and add compost to enrich the bed and encourage healthy plant growth. It's also a good idea to do a soil test to determine if you should add any nutrients your plants need to look their best.
An inverted cardboard box, frost blankets, sheets or even a tarp can help. If possible, rig up something to allow air space between the covering and plant. I have used tomato cages or stakes with a sheet and tarp over them. Leave the plants covered until we are back up above freezing.
However, exposure to water or humidity is highly destructive toward cardboard mechanical properties. Water-soaked corrugated cardboard can easily collapse with irreversible shape distortions. Various treatments have been developed to render cardboard hydrophobic including wax layers and nanoparticle treatments.
The cardboard layer breaks down after several months (depending on soil type and geographical region) and the mulch will begin to decompose through contact with the soil. There are several advantages to sheet composting: It is an easy and uncomplicated method of composting.
Depending on how and where the cardboard is made, it can contain a long list of chemicals and glue compounds, both of which can leach into the soil. Add to that, many cardboard products also contain man-made ink compounds that can also soak into the soil as well.
A single layer of cardboard is laid out over the areas of lawn no longer needed. When it eventually breaks down, the cardboard will add carbon back into the soil. A crack in the cardboard reveals hardy weeds making their way to the sunlight. Extra mulch will solve this issue.

Pull out as many weeds as you can. Then, lay the cardboard down on the ground and then cover it with a few inches of pea gravel.
Termites were found to prefer cardboard over wood chips as a food source, and rodents such as voles often nest underneath mulch sheets. 2) Newspaper and cardboard sheet mulches were often not as effective as other organic mulches (e.g. wood chips or bark) in preventing weed growth or improving yield.
DEFINITION: Sheet mulching is a technique of laying cardboard or newspaper over an existing lawn and then topping it off with layers of compost and wood mulch. The layers suppress weed growth, giving you healthier soil and plants. Lay down weed barrier: 2-3 layers of B-flute card- board (rolls or salvaged boxes).
In fact, termites will typically only eat the wood inside of a structure for the cellulose material it contains. This, unfortunately, means that any plant-based materials that contain cellulose, such as cardboard boxes, paper or even leaves, could attract termites.
When it comes to pests, cardboard boxes are not your friend. Cardboard is susceptible to moisture and humidity and attractive to many types of insects. Use plastic bins with lockable lids.
