Walnut shells are considered extremely beneficial for the garden. This waste will be an invaluable help to gardeners in every respect. Few people suspected that the hard shell contains a huge number of elements beneficial to plants. There are countless ways to use it.

Mulch

Walnut shells are excellent for mulching the soil. A lengthy decomposition process, resistance to sunlight and high moisture resistance make them an ideal material for covering the ground. On top of that, the sharp edges will keep slugs and snails from reaching the harvest.

Drainage

The nut shell can be used as drainage in low-lying areas of the garden where water often stagnates. It can also replace store-bought expanded clay, which is needed when working with seedlings.

Disinfection

The shell contains the phytoncide juglone, which actively destroys microorganisms and repels insects. To disinfect the soil, you need to crush the halves and pour hot water over them. The finished infusion will then need to be diluted with liquid in a one-to-two ratio. After such treatments, even the Colorado potato beetle will not dare to come near your plot.

Fertilizer

The waste left over from the nuts can come in handy as fertilizer. It needs to be burned in a barbecue grill or in a stove, and then the resulting ash applied at the roots of plants. Such feeding contains magnesium, potassium, phosphorus, as well as other elements necessary for the growth and development of vegetable crops, according to the «Dacha on Six Sotkas» portal.
