If I had concerns like yours, I would take the plant out of the container, clean off all existing soil and inspect the root ball. If any dead-mushy-slimy or black roots, trim them off.
Personally, I would pot up single stems separately (looks like there is few of them, and reasonably thick).
Make sure you don't over water - water when dry, not necessarily on schedule.

Seems to be quite compact, so I guess it is receiving enough light? Is it indoors or outside?

Hi Rina. Thank you so much for your feed back. I will follow your advice and inspect the root ball. I also agree with you on potting up single stems separately - the only challenge is finding a sunny space for 3 pots instead of one as I am growing my plants indoors :-)

Agree with Rina. These need as much light as you can give them for optimum health and growth. I personally like a single stem per pot as well. If you are able to put it outside, it will benefit from it. I have some of mine indoors, a few outdoors. If I didn't have squirrels, groundhogs, skunks and raccoons digging things up and nibbling on leaves, I would put more outside. Here is one of mine today, enjoying the outside. Good luck with yours.

Thanks Christopher! Thats a very nice one. I wish I had the chance of putting them outside, but I live in a 4th floor apartment. Just trying to grow as many green plants as possible in there, as a substitute for a garden :-)
