'Magic fertiliser' made from kitchen scraps has '100% success rate' for flowering and fruiting plants

The gardening enthusiast claimed on his YouTube channel Zen Garden Oasis that vinegar is necessary to enable calcium absorption from eggshells.

“One of the most critical things that your garden needs and your soil needs is calcium, I’m going to show you the most bio-available calcium you can make with kitchen scraps," he explained.

“Eggshells are 95 per cent calcium but that calcium is not readily available until it is changed from one form of calcium to the other.

“You have to go through a process to make it available to your plants."

The first step involves washing the eggs in piping hot water to help the egg membrane separate from its shell.

This will also ensure all the moisture is extracted from the shells before proceeding to the next stage, noted the gardening fan.

Next, he recommends crushing the shells down by hand before adding them to a smoothie blender.

“The goal is to turn the eggshells into a very fine powder,” he told his followers.

To create the ultimate fertiliser, combine one part powdered eggshell with 10 parts vinegar, instructed the expert.

This solution needs seven to eight days to completely convert into bioavailable calcium.

The title of the video claims the mixture becomes “magic fertiliser” for all vegetables that boast a “100 per cent success rate”.

“Turning the eggshells into a powder is going to speed the process up by up to a thousand times what it would be naturally,” explained the YouTuber.

Gardening expert Sam Marlow claims eggshells can also keep slugs and snails away from your vegetable garden.

The Royal Horticultural Society says the netted field slug, brown soil slug and common garden snails are the species most frequently spotted in British gardens.

Annoyingly, keeled slugs are sometimes found creating holes in potatoes and other tubers.

Marlow, from Garden Building Direct, told GB News: "We all know that kitchen waste is great for compost, but did you know that there are other uses in the garden for kitchen waste?

"Crushed eggshells sprinkled around the base of plants can deter slugs and snails, as the sharp edges irritate their soft bodies."
