Yana captioned her post: “Grandma method! Don’t throw away the egg shells.”
In her video, Yana demonstrated how you get cracked egg shells to a homemade, natural fertiliser.
Firstly, place your egg shells in a bowl and run them under cold or hot water.
Place the shells onto some roll, before placing them in an oven-safe dish or receptacle and into the oven for a few minutes.
Pour the dried egg shells into a hand blender, blitzing them into fine crumbs.
Then, pour the fine crumbs into a jar of your choosing.
When ready to use, sprinkling the egg shell crumbs over the plants and onto the soil liberally, too.

According to, eggs contain other beneficial nutrients and minerals, such as small amounts of phosphorus, magnesium, potassium, zinc, iron, and manganese.
These nutrients can help reduce acidity in the soil, help rapid growers which can suffer from calcium-deficient soil, as well as a deterrent for pests like slugs and snails, according to
The experts explained: “As a plant food, egg shells are therefore perfect for lime-loving plants such as brassicas, but are best avoided as a food for acid-loving plants, such as rhododendrons.”
Egg shells can be used as plant food for the likes of vegetable crops, including potatoes, cucumbers, peppers, courgettes, marrows and squash.
However, GardenersWorld experts warned against using them for “lime-hating” plants, such as blueberries, rhododendrons, pieris and azaleas.
