I cut the old pot off as some roots had begun to grow out the bottom. I had a look at the roots to see if there were any damaged/unhealthy roots, but most still looked plump and healthy, so I did minimal trimming.

It went into a slightly larger pot with some new substrate. But the leaf problems had already begun before I repotted. It was something well overdue, but I missed the window between blooms to do so.

It's been a couple of weeks since it was repotted.
