I'm no expert but in my opinion it looks overwatered, is the stem turning black at all? I can't see in the photos sorry

Does the pot that you're using have a drainage hole? If not I would repot it to something with one

Hi! The stem is firm and no black. It's an unglazed terracotta pot with drainage hole.

I guess if the stem is firm that's a good sign! If it was me i would take it out of the pot to check for root rot, remove the very black leaves and stop watering it for a while but I am very much an amateur haha so take my advice with a pinch of salt :)

I hope your plant gets better soon

Agreed with Jeff. Maybe your soil mix is staying to wet still with winter and not performing as you would like it to.

I agree with a root check. Afterwards, be sure to check the soil with a skewer before watering to see if it's needed. If the soil is very wet, you might use fresh soil.

And by 'fresh soil' I would suggest 'porous soil', one that has lots more material to help the medium drain, such as pumice, perlite, or chips of decomposed granite.

Thank you everyone! I will take it out tonight , I'm thinking proportionally less potting mix this time. Do I need to leave the roots out for a few days before repotting? I admit I've put them straight into a fresh mix previously. And then hold off watering for 1-2 weeks?

Would you still recommend removing the black leaves if I add that they feel firm and healthy (despite their unhealthy appearance!)? I've just noticed that the poorly coloured squishy ones (most of the leaves on the plant) also look more swollen than the bright green/red ones... definitely over watering / lack of soil drainage.

If you break any roots or cut, it is better to leave out to callus - 1 day is plenty. If they are wet, let them sit on something absorbent to wick off extra moisture, then pot. I wouldn't use any more than 30% potting mix (I am assuming that this mean bagged soil?).

The plant is quite overwatered, as you are aware. Water logged leaves will fall off, I would take off any blackened - just to make sure there is no possibility of rotting. JMO.

Ok so the good news is there's definitely no root rot and main stem is still firm. Not so good news is that peripheral branches are now soft and drooping !

I would cut one to see what is happening: they may be rotting, you should check it out. It also looks like a frost damage I have seen once, but not sure. If frost damage or rot, they will not 'repair' themselves. Sometimes they wrinkle and droop when very thirsty, but those blackened leaves look worse than dehydration, IMO.

Cut the branch and take good photo of the flesh and post.

Ok have removed the worst one, rot would be black and mushy right? Looks ok...

Looks okay. Did you take any photos of the roots while you were at that?

I didn't notice how you assess need for water. If you are just going by time, consider using a thin wooden skewer deep into the soil, midpoint between trunk and edge of pot. After ten minutes, remove and check it. If completely dry, water. If cool and slightly moist, use your best judgement. If wet enough to have bits of soil stuck to it, don't water.

Sorry but I don't think these cut branches do look ok. Just my opinion and hope I'm proved wrong. There shouldn't be the dark area at the edge of the cut surfaces, it looks waterlogged either from overwatering or cell damage due to cold. I think that's where the problem lies as I suspect it's rotting from the outside. Don't know where you live so no clue as to temps, does it reside in the house, if so is it kept warm/cold? Best to add location like most members do:-)

Thanks for all the comments. sorry - I live in the UK. It's been in the conservatory window, which isn't heated so does get quite cold. Have currently moves it into the adjacent dining room where it's warmer. Do you think i can save it?
