How does it work?
Boil your eggs like you always do. When they’re done, carefully take the eggs out and let the water cool down in the pot for a while. Then, when the water has cooled down to room temperature, you can pour some of it on the soil of your plants. Give them the same amount of water as you normally would.
Were you planning on trying this trick but did you accidentally mindlessly throw out the water anyway? Don’t worry; you can also use some eggshells instead. Just place these on top of the soil. This works about as well as the egg-water – it just looks a little strange. When you try this trick, do remember to push the eggshells into the soil a little bit.
