Egg shells are a great fertilizer for plants that need calcium to live a happy life. They are excellent for both indoor and outdoor plants, including utility ones. Eggshells promote plant health, growth and flowering.
How to use eggshells
Egg shells are an excellent fertilizer only if you know how to use them properly. First, it is important to dry them thoroughly. That is, so that they are perfectly dry on the inside – without sticky whites and traces of yolk. If you are sure that the shells are really perfectly dry, break them into as small pieces as possible. It’s great to use a pastry roller. Then all you have to do is fairly divide all the plants and rake the surface with a rake so the shells don’t just stay on the surface of the substrate.
Egg shells are also recommended to be used instead of mini pots especially in spring for sowing useful plants like tomatoes, peppers, cucumbers and many more. When you plant these seedlings in a bed or pots outside, crush the eggcups and place them in new soil under the seedlings. Crushing them will speed up the decomposition of the eggshells, promote successful and healthy growth of the seedlings, and also allow them to take root in the new soil. It would be difficult for them to find their way through the egg halves.
You can also use eggshells to make liquid orchid fertilizer
Yes, you can also make a liquid fertilizer from egg shells, which is especially great for orchids. Again, the eggshells must be crushed into as small pieces as possible. The smaller the pieces, the more nutrients will be released from the eggs and the better your liquid fertilizer will be. Pour warm water over these shells and leave them to infuse for a few days (roughly two weeks). Leave them like this in a room where there is not much light, dark is best. After this time, when the shells have sufficiently leached, just drain them and start using the fertilizer in the same way as any other fertilizer.
