I’ve slowly begun to notice that a few of my plants that did well for a while are starting to decline now that I’ve had them for a few years. For example, a Lepanthes felis was thriving for about three years, and declined quickly and then died. My Lepanthes dodsonii seems to be following a similar trend, and a couple others from the genus, especially those with softer leaves. The main symptoms are that the growth just slows down, and the old growth just gets kind of ratty and is never really replaced. It doesn’t seem like any kind of disease. Is it possible that these plants are just dying of “natural causes” after 3 years or so? Another possibility I’m considering is that the mounts (hard tree fern) undergo some kind of negative change as they get old. The mounts are still hard and not rotting, but maybe there is an issue with the pH? Basically, I’m good at getting the plants to thrive short-term, but long-term success seems a lot harder. If anyone has any ideas, I’d love to hear them!
