What’s going on with my string of bananas? I have this as a cutting about 3 years ago and I am very proud to have it flourish under my care. Plant looks awesome overall but I just noticed abnormal growths. And there’s a couple.

It’s growing these potato-like galls (1st pic). 2nd pic shows the galls vs normal air roots. 3rd pic is to show how the plant looks overall.

I’m in zone 6a. Western MA.
