    Is shark cartilage a good nutrient to give orchids? I read that some people use crush sandstone or bone as a extra nutrient with fertilizing but what about shark cartilage? I know its weird/strange question to ask like some others I asked in the past(that I had no guts to try yet) just thinking outside the box.

    I would be concerned that while sandstone and bone are in good supply, sharks are having a hard enough time as it is. What nutrients are you expecting to get from it?

    Marni,
    Thats what I want to know, because I have a local herb shop near me that I get acacia sap for my sugar glider and seen they have shark cartilage and wonder if it could be a added benefit for orchids. Not that I'm going to try it(I stick with the regular and tested orchid fertilizers), just curious:)

    One product claims that 750 mg contains

    Calcium 270 mg
    Phosphorus as phosphate 142 mg
    7.5 mg sodium
    Magnesium 3 mg
    Potassium 1.5 mg
    Zinc < 0.7 mg
    Iron < 0.03 mg
    Iodine 0.02 %
    Heavy metals <10 ppm

    There are better, less expensive products with less of an impact.
