If you’ve grown orchids for a while, you’ve probably run across the question of using eggshells as a calcium supplement for orchid fertilizer. When you start researching what all goes into the fertilizers, it’s almost natural that you’d want to take a step back and refrain from commercially produced brands. The chemical overload in these fertilizers is nothing to joke about. The next step in this thinking process, is why not make your own? Eggshells, banana peels, tea bags, molasses, cucumber skin, potato rinds, coffee grounds… What is actually a good idea for a fertilizer supplement, and what is a pure waste of time? In this video, I’ll focus only on eggshells, and the pros and cons of using it as a fertilizer in your orchid potting mix. Do eggshells provide any benefits to your orchid? Eggshell fertilizer benefits your orchid by strengthening the orchid’s cell wall, making it stronger and less prone to outside influences, like root rot. Calcium from the eggshells also reduces salt build-up and prevents chlorosis. The cells will become sturdier and firmer, and in the long run, the orchid’s growth will become larger.
