Imagine breaking an egg into a frying pan and throwing the shell in the trash.
Stop! You just threw away free fertilizer, insecticide, and even a mini-greenhouse for seeds.
Now we will tell you how to turn ordinary garbage into gold for your garden.

Shells vs. Slugs: Who Wins?
Slugs hate eggshells more than salt. But to create an impenetrable barrier, the shells should not just be crushed, but baked in the oven for 10 minutes at 180°C. This will remove the remaining protein that attracts pests and make the edges even sharper.
Sprinkle the "prickly" powder around hostas, cabbage and strawberries - slugs will prefer to crawl around your beds a mile away.
An added bonus: as the shells gradually decompose, they will reduce the acidity of the soil, which will be appreciated by roses and peonies.
The Secret to Blooming Orchids: Shell Drainage
Orchids die not from lack of water, but from its stagnation. Replace expanded clay with large pieces of shell - they not only remove moisture, but also release calcium carbonate, which neutralizes hard water.
Before using, boil the shells for 5 minutes to kill bacteria.
After six months, you will notice that the orchid roots have become thicker and the flowers last 2-3 weeks longer.
Egg "pots" for seedlings: eco-technology
The shells are an ideal container for plants with fragile root systems, such as pumpkins or cucumbers.
Carefully cut off the top of the egg, fill the shell with a mixture of peat and perlite, plant the seed. When the seedlings grow, lightly crush the shell in your hand (so that the roots can break through) and bury it in the ground.
The calcium in the shell will speed up growth, and the shell will provide additional protection against the mole cricket.
