Our Paph is doing very well thus far, with many blooms. However, we have
noticed that a couple of leaves have become yellow over time. They are
usually the ones at the very bottom. Does that indicate overwatering ? We
usually water once a week, and fertilize every two weeks. We would
appreciate some views. Thanks !


That is probably normal. No leaves will last forever. Over the course
of a few years, you will eventually lose the entire fan. By then,
hopefully, your plant will have grown several new fans of leaves.

You will want to repot your paph on a fairly regular basis. I recommend
once a year. I don't always get a chance to practice what I preach,
though. At repotting time, you can assess the condition of the roots.
If you are overwatering, you won't have many.
