adding calcium
 

Hi all, as I was adding some calcium to some of my orchids this AM I got to wondering if there was any that I should NOT add it to. I have mostly Cats, Paphs, Neos and Phals.
Thanks for the info....Jean

Paphiopedilum & Phragmipedium Intro Page - AnTec Laboratory:hello Check out ladyslipper.com for paph info.

I use quite a bit of calcium on my orchids and I haven't had any problems. Cattleyas, Paphs and phals all grow stronger leaves and stems when I use calcium. I don't grow Neo's so I can't advise you on those.

I use Calcium on everything. I add it to my water in the summer as most of my orchids are in full growth mode and then rely on the eggshells for the winter (I am constantly adding eggshells to my orchid pots).
I don't really grow Paphs, though, but I do have Cattleyas, Neos, and a few Phals.

All orchids need a regular calcium supply. Some need more than others.

Before you go adding it though, I'd verify what's in your water supply, as it may-, or may not be necessary to add more. That said, unless you overdo it, I doubt it hurts to provide a little extra.

Where would an orchid growing in the tree tops find a source of calcium?

Thank you DeaC for the link to that site, very very informative.l am sure I will be revisitingit it often. (My memory isn't what it used to be lol) Thanks again...Jean

Tucker,leafmite and Ray thank you for the the info, always good to hear from the horses mouth that I didn't kill anything. Would you use oyster shell or a water soluble type? My preference would oyster shell. OK?
Thanks again....Jean

Cambria What, that is a question! Anyone have an answer?...Jean

Monkey poop, bird poop, lizard poop, bug poop, decaying leaves.......

and from the organic debris that collects around the roots.

Bird droppings for sure.
