A tip you might want to try is fabric pots. I use "Smart Pots" since it's a reputable brand (and I'm hoping these have a better chance of lasting), but I'm strongly suspecting that the brand really doesn't matter functionality wise.
Why fabric instead of rigid pots? It serves several purposes:
- ​Air pruning: Root tips dry out when they hit the wall which triggers lateral growth instead of spinning into a dense rootball around the pot (main reason people use aerated pots)
- Soil aeration: Air can get into the pots from all sides, which increases the aeration of the soil, likely with a positive impact on the microbiome and e.g. nitrogen fixation
- Wicking: The fabric wicks the water all around the pot which increases the homogeneity of the water distribution through the soil, quite noticably
- Wetness: It's extremely easy to detect if the soil is wet or not, and how much and deep, though simply putting your hands on the fabric
- Drying: The soil drains much better in fabric since it can evaporate from all sides and not only the top, reducing the time window the soil stays dangerously wet
The two last points, and maybe also the soil aeration, would probably be of use in this case (although I don't recommend repotting that plant until it looks more healthy). I really find fabric pots super neat and can't speak highly enough of them. If you have problems with water logged soil, give them a try. Not wanting to spend money on them? Try to sew your own from some strong airy fabric (e.g. potato sacks or something)!
