Egg shells - This is something an old woman told me once. She said that the secret to her beautiful plants was a biweekly shot of egg shell water. Making egg shell water is a simple enough task. First, take the egg shells of six eggs. Put them in an oven at 300 degrees for about 15 minutes. Take them out and stuff them in to a 1 gallon water jug which may be capped. Fill the jug with hot water and let it sit in the sun for about a week. After that time, shake the jug vigorously and water your plants liberally.
As you may have guessed, the calcium from the shells probably leeches out during the time in the water, thus producing growth spurts. I have tried this myself except that I did this once a month during my normal feeding/fertilizing time. I did notice a spike in growth and I have been doing it ever since.
I'm curious, does anyone know why you set it in the sun? How would one make this stuff in the winter?
