Oyster Shell - calcium top dressing
Orchids, such as Paphs, Phrags and Oncidium, all love an addition of extra calcium in their growing medium. We are offering loose crushed oyster shell to add as a top dressing to your current mix. (please note that our own Paph & Phrag mix, as well as our Oncidium mix already contain this ingredient).
Just sprinkle a bit over the top of the mix and each time you water, the calcium is released to the roots, making your orchids extra happy!
Each bag is about 1.25 pounds. Please note that oyster shell is heavy, so the bag is actually quite small.. about 4" x 6".
