3. Valuable Eggshells
Eggshells are often discarded like trash, but they can actually be very useful to gardeners if you know how to use them properly. You might have even seen your grandparents use this trick if you were raised in a green thumb family.
All you need to do is gather up your used eggshells, pound them into a fine powder, and then mix them in with your soil. You might be wondering what you could possibly achieve with all this violent pounding.
The answer lies in nutrition. Eggshells have a very high calcium content. Much like humans, plants and flowers also need calcium to grow healthily.
While it might not be for teeth and bone strength, calcium is an important part of the diet of your plants. If you have an excess of eggshells, you can store the rest of them in a container and then smash them up whenever you need to give your plants an extra boost.
