A monstera obliqua (houseplant)

Question

My small Monstera obliqua (or adansonii) has one very yellow leaf and another that is about to turn. I have had the plant about 6 weeks and without realising its light requirements, I did leave the plant in direct sun on the windowsill for a few days which burnt a couple of the leaves and they lost some colour straight afterward. Since then I have tried to keep it in shade, the yellow leaf wasn’t one of the sun damaged ones.
I repotted it about 5 days ago after I noticed the roots coming out of the drainage holes at the bottom of the original pot. I didn’t water it after repotting and haven’t done so yet (because of the yellow leaf).

I started out watering with rainwater, but changed to tap water about two weeks ago. The plant had two waterings with tap water and then started to go yellow. I don’t want the plant to die – if it’s root rot will it spread to the other roots? The other side of the plant looks reasonably healthy. Should I cut off the yellow leaf or let it die until it falls off?
Thank you. I am in southern England and the weather has been sunny and warm for the last month or so.

Answer 1

I don’t know how much chlorine is in your tap water, but in our country there is quite a bit. This plant will not tolerate tap water here. This resembles chlorine toxicity. You can cut it off after it has completely dried.
