I have a rather mature rabbits foot fern which has larger and more brownish rhyzomes than the types I usually see at stores such as Lowes. The leaves are also much larger. This is the first year it has produced spores on the underside of its leaves.
Is there a way to tell by looking at the spores shells if they are about to drop the spores? I have been pulling off a frond every week for the past 3 weeks and placing them between two sheets of paper and still nothing has been dropping from the fronds on to the paper.
I didn't know if it was a timing thing or if there has to be a certain amount of light/humidity/temp for the spores to release. It might just be that I am pulling the fronds before the spores are ripe??
Any ideas?
