I recently bought a couple of tiger lotus. One had three or four leaves, a full bulbs, and lots of roots. The other seems to just be sprouting and has a heavy bulb with no visible roots like the larger one. Unfortunately, the larger plant has not done well with all its leaves except falling off after seemingly rotting/weakening at the base of the stem. Now one leaf is left barely hanging on by a somewhat translucent section of stem attached to the bulb. The roots look healthy and strong still. Can this plant recover and is there anything I can do? Also, for the baby, sprouting lotus, is the lack of obvious roots a worry? The bulb and stem seem sturdy and healthy as of now. Thanks for your help!
