When learning to grow them, in your own way, and in your own local conditions. Be cautious, make changes slowly. After any period of being dry, I've always had some difficulty when starting the plants back on water. For whatever reason, some fail to successfully adjust to having water, again. It can be very frustrating.
Many plants, including these, can be quite adaptable. Or they can fail, suddenly, and unexpectedly. Like many things, especially caring for living creatures, there are many different environments in which they can survive or even prosper. Of course, we caretakers need to decide for ourselves, what that constitutes for us and our plants. If they survive, and continue, for some, that is enough. With others, they tweak and tweak again, until the plants seem to reach a peak of health and vigor, they may not even be capable of in their native habitats.
