Crushed Oyster Shell
Important to the health of limestone (calcium carbonate) loving Paphiopedilums. In nature, they are frequently found in limestone outcroppings.
Other orchids such as Phalaenopsis, Cattleya and Dendrobium do not like excessive calcium carbonate. This product is not for them.
Add 1 heaping teaspoon to the pot every three months.
This is a small container weighing about 350g. Oyster Shell is a natural organic source of calcium and trace minerals for calcium loving orchids such as Paphs. It is 96% calcium carbonate , a gentle source of elemental calcium. Use as a topdressing and replace when gone. The variable particle size allows for immediate and long term release. Oyster shell is basic and is used to raise pH in orchid mix.
