Using Eggshells in the Garden

“Crushed egg shells add valuable nutrients to soil. Calcium is essential for cell growth in all plants. Calcium is especially important for fast growing plants because they quickly deplete the surrounding soil of calcium. Using eggshells in the garden is a great way to make use of something that would normally just get thrown out. You can put eggshells in compost, in soil or use them as a kind of organic insecticide, which means that not only are you helping reduce trash, but helping your garden too.”

Eggs

Holidays have a way of dredging up old memories, for example my Swedish grandmother’s method of putting a dried, crushed eggshell into her old percolator along with the coffee grounds. My grandmother’s people came from the north of Sweden where nothing is wasted, but did putting eggshells in the coffee make it better?

Actually, it probably did. Eggshells are made up of primarily of calcium, which readily leaches into warm, acidic liquids like coffee, which has a pH between 4 and 5. Like a low dose of lime, the eggshells probably raised the pH slightly and mellowed its flavor. They also probably enriched the coffee with dietary calcium, which Grandma Ruth would have loved had she known about it.

Indeed, recent research has shown that consuming eggshell powder as a dietary supplement increases the formation of both cartilage and bone in people with osteoporosis, and can significantly strengthen bones of post-menopausal women.
