Is this due to root rot? Temps? Or something else? Leaves have been curling down due a few weeks, and now they are starting to droop and dieback quickly over the last few days. There is some new growth still though. Do I need to uproot it and check / cut roots?
Does the pot feel lighter than it should? Does the pot have good drainage? If the answer to both is yes, you should let the pot sit in a container of water for several hours. Potting soil can dry out to the point where it is very slow to absorb water, meaning the water will run out the bottom of the pot before it has a chance to be absorbed.
If the pot does not have good drainage or it feels heavier than it should, it's possible the soil has too much water in it. Correct the drainage issue and the extra water will fix itself.
I know what I'm asking is very subjective, but hopefully it makes sense. You can also stick a finger into the soil to the second knuckle to see how dry it is. Let us know what you find either way.
I repotted the plant last year in a massive pot that takes 2 people to lift, so it's hard to tell by weight.
The soil seems damp but not wet. I watered yesterday. I drilled a hole in the bottom of the pot when I repotted, and water does seem to drain onto the saucer underneath the pot.
