Many people are unaware of the benefits of using walnut shells and believe that they are useless and can be thrown in the trash.
However, there is a very useful use for waste in the form of shells. This nutritious material will definitely come in handy if you have plants on your windowsill.
How to use nut shells
Drainage
The shells rot very slowly in the soil, so feel free to use them as drainage for indoor plants.
The shells must first be crushed and can be embedded in the soil. The nut shell will decompose in the soil for up to 10 years, unless mixed with other fertilizers, which will accelerate the rotting process.
Pests
Walnut shells will help save plants from the invasion of garden pests. If you notice slugs or snails in the beds, sprinkle crushed walnut shells and the "enemy" will not get to the plants.
Mulch
The shells are good as mulch, but you will need a lot of them and they will have to be crushed.
