  1. Egg shells

Egg shells, also considered diatomaceous earth, can be used for many backyard remedies and projects. The eggshells can act as a fertilizer. Due to its earthly origin, the hard-shell remnants keep away insects from the tiny sharp pieces being harmful to them. All you need to do is finely blend the egg shells, using a food processor. Dust the powder around the root of the plant, damaged leaves, and around any vegetables. Use as needed.

The eggshell fertilizer technique is known to keep away slugs and japanese beetles in particular. Which can certainly help when preparing and maintaining your garden. As there are multiple uses for eggshells, you can also use the crushed pieces in your compost.

  1. Oil + Soap Spray

This is a very simple one to make, all you need is vegetable oil and a biodegradable mild soap. Get a sprayable bottle or reuse an old cleaning bottle if you’re feeling extra green (suggest rinsing with the mild soap prior). Mix the combination in a separate container than the one you’ll be using to spray. One cup of vegetable oil combined with one tablespoon of soap, shake well immediately before use. Take your standard sized cleaning spray bottle (32 ounces) and mix one tablespoon of the oil mix and the rest of the bottle with water. Shake well and use as needed.

  1. Garlic + Mint Spray

As intense as it sounds, mixing a Garlic Mint Garden Insect Spray has its potent scents and flavors fighting insects off your vegetable and herbs plants. Start with putting garlic and mint into a food processor. Take blended mix and transfer into a pot of boiling water with a tablespoon of cayenne pepper. Let mixture settle over night. Fill standard size cleaning spray bottle with the settled mixture and one tablespoon of biodegradable mild soap. Shake well and use as needed.

Who would have thought? Mixing both a vegetable and an herb to help each other out!

  1. Chilli Pepper Spray
