Vee, what I might do if I were you is just repot in new soil and see if the advice from that page is right. While you do it, look at the roots and see how healthy they are. I don't remember if this one has swollen nodes in the roots or not, (like little tubers) but that is a good thing. You might cut off the worst of the leaves but not all. I'm saying this because out of all the plants in this family that I've done this to, the red prayer plant and I would include M. marisela also, did not do as well coming back as all the others. I think in my case is that my plants had stingy roots. See how the new growth comes in. If it is the same and you are not happy with the results, you have nothing to lose by cutting it back as it is an easy plant to replace.
