Plants will grow better and faster. So when you boil the eggs, don't rush to pour the water, but use them to water the plants. This way both saves water and helps the plant grow stronger.
Doing:
You boil eggs like you usually do. When you're done, carefully remove the egg and let it cool in the pot for a while. Then, when the broth has cooled, you can pour some egg broth on the soil to replace the regular white water. Every day water boiled eggs 1-2 times you will notice unexpected results.
2 ways to use egg shells to plant trees, without buying fertilizer
Method 1: Grind (or crush) eggshell (both raw and cooked) and mix with soil to plant or compost normally. The small grinding helps egg shells easily decompose and becomes a source of mineral supplements for the soil. In addition, they keep soil loose and help plants grow better.
Method 2: Make fertilizer from eggshell combined with banana peel and coffee grounds. Banana peels are rich in phosphorus and potassium. Coffee grounds contain 2% Nitrogen and are an excellent natural source. In addition, coffee grounds provide both calcium and magnesium.
You just need to chop the banana peel, grind the eggshell and coffee grounds, add some regular water or water the rice if necessary. This mixture can be applied to plants or mixed with new soil.
