This question may have been asked and answered several times so please forgive me... If I harvest pollen from, let's say, a Paph or Catt or Phal, how long will it "keep" and under what conditions does one store pollen?
I've used Cattleya pollen approaching 6 months. Phal seed is notoriously short lived, but I don't know if this translates to Phal pollen. I don't breed Paphs so I can't help there.
I recently stopped refrigerating anything tropical and have not noticed any issues. I now store my seed and pollen on a cool, dark, dry shelf at room temp. The only items that I store cold are seed from temperate species.
