My friend has a four foot plant she was told is called Mother-in-laws tongue. Half of the plant stands tall and stiff. On the other side the stems are folding over to the floor and pulling themselves out of their soil. As we tried to clean it up a bit a few of the stems are so week they pull out of the soil as if they are rotted off. If we were to cut the plant down, to encourage a fuller plant as you do with some, the edges would be so rough and unsightly. What could be wrong? Does it need more sun? Less water? It is very dark green and healthy looking other wise. Is this common and needs to be accepted? She had it tied up with a cloth to the bannister. We untied it and turned it so now the leaves are propped by the banister but with out the cloth. We are not so sure this is good for the banister. Any suggestions would be welcome.
