Most people throw cardboard boxes away without a second thought. But one gardener discovered they can become an incredibly useful tool in the garden — while also saving a lot of money.
At first, he did not believe the trick himself.
Using cardboard on garden beds sounded like one of those strange homemade hacks that rarely work. But after spending too much on weed control and soil materials, he decided to test it in practice.
He started by laying ordinary cardboard boxes between the beds instead of buying expensive covering materials. Before using them, he removed tape and labels, soaked the cardboard with water and placed it directly onto the ground.
Then he lightly covered everything with grass and soil.
The difference appeared within weeks.
Weeds almost stopped growing completely under the cardboard, which meant far less time spent pulling them out and no need for chemical weed killers.
The cardboard also helped the soil stay moist much longer, reducing how often watering was needed.
Later, he began using the same method to create new garden beds. He simply covered grassy areas with cardboard, added compost on top and waited. After several months, the ground became soft and fertile.
Another bonus came from nature itself.
Earthworms gathered underneath the cardboard, naturally loosening the soil and improving its structure.
The method even worked inside the greenhouse, where cardboard pathways helped prevent mud after watering.
Still, there are a few important rules. Glossy or heavily painted cardboard should be avoided because it may contain harmful substances. Plain brown boxes work best, and they should always be wet before placing them outside so the wind does not blow them away.
Now the gardener says cardboard has become one of the most useful and cheapest things in his entire garden.
