Unfortunately this plant isn't doing well. Following the advice in this thread I watered it more often. About 2 months ago I noticed more leaves yellowing. I pruned them assuming it was some seasonal shedding.
I was away on holiday for 2 weeks and came back to this (2nd April 2022). Compared to the pictures earlier in the thread (July 2021), the plant looks very bare.
A close-up of what's happening to the leaves:
There is still some new growth at the top.
The pot (the soil got dry very fast so I put some pellets to keep it moist)
Can anyone help me? I've had this plant for a long time and really don't want to lose it
