I bought a small clump of Java fern from petsmart a couple months ago and for the first month it seemed to be having some trouble adjusting. I usually ended up wiping the diatoms off each leaf a couple times a week but then it seemed to take hold and start growing, there's even a bunch or pearling going on. One thing I have found strange is that on each leaf a plant is growing at the tip of it. I see some new leaves coming up from the roots but mainly they're growing new plants on each leaf. Is this normal? Just doesn't make sense to me considering I have to break off the small plant starts from each leaf to tie it onto the wood.
