Calcium-Magnesium Info

To make calcium spray for plants with eggshells, boil 20 eggs in a pan covered with 1 gallon of water. Bring to a rolling boil, then remove from heat and allow to cool for 24 hours. Strain the water of shell fragments and store in an airtight container in a cool, dark place. Another way to make homemade calcium rich foliar spray is by filling a gallon jar with water and eggshells. Steep for one month, allowing the eggshells to dissolve and filter their essential nutrients into the liquid. To create your calcium foliar spray, mix 1 cup of the resulting solution with 1 quart of water and transfer to a spray bottle. This homemade calcium rich foliar spray is also rife with nitrogen and magnesium, phosphorus and collagen, which are all essential nutrients for healthy growth.
