I have 3 pieces of a.nana, each about 4-5" long, growing in one area of my tank. Tho they have really healthy roots along the length of the rhizomes, each section seems to leaf primarily from one end, with only a couple of leaves along the rest of the rhizome.
I would welcome thoughts of how you would manage these plants.
Would you suggest slicing off the relatively unproductive sections of the rhizome?
Leaving well-leafed and rooted sections of how long?
Would you keep the other sections - either to establish a thick bed of a.nana, or to get some growth to trade in to the LFS?
If propagating them for sale/trade, how long would you make each section of rhizome?
Need each section include leaves?
On another topic, while my a.nana is doing pretty well, my congensis and frazerii seem pretty static. They occasionally send up new leaves - maybe every month or 2. But root growth is VERY minimal - far less than with the nana. Any thoughts? I don't currently add iron. Ought I start? (There may be a small amount of Fe in TMG - I'm not sure. And I just finished a bottle of Flourish. I figured my next bottle would include iron.)
