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.

It may be getting too dried out. As it grows, it requires an increasing amount of water, especially in the strong sunlight. Potted as it is, it will be nearly impossible to over water. Water before the surface of the soil gets completely dry. It may require 2 or 3 waterings every week. Err on the side of too much rather than too little.

This plant tends to get leggy and weedy so regular pruning is always good. As an alternative, once any stem reaches the preferred height, just pinch out any new shoots as soon as they emerge. That is the best way to maintain te staus quo.

Thanks, Will! Based on your description, I am underwatering. Do you think it's better left in this pot? I have one size larger available.

Last time I increased the pot size, it didn't seem to appreciate the change for a while, which is why I've been hesitant.

Your choice is to water more frequently or move it to a pot one size larger. If you do repot, disturb the rootball as little as possible to minimize root damage and transplant shock
