I've had this plant about two years. Last year I gave it a good prune and now it's grown back to the same size before the pruning. I haven't changed its location, this is south facing. A couple of months ago, a leaf here or there would turn yellow and dry up and fall off. No biggie, but it's continued and now I'm wondering what is causing it. And there's no pattern- it can be any leaf anywhere on the plant. No signs of bugs anywhere.
Watering? Natural shedding? Needs another pruning? No roots growing out of the bottom and it's got new growth. Last repot was about 18 months ago.
