If the trunks divide at or just above the soil line, I'd keep it as a twin trunk. If they divide several inches above the soil line, I'd probably remove one - and I base that purely on aesthetics. Trunks that split well above the soil line don't look as natural as those that split lower.

I'd prune back to where the plant started to get leggy ...... which is the plant's way of telling you it wants more light. A side benefit to truncating the trunks is the lateral branching that will follow. I don't expect a very enthusiastic response because of the light issue, and you'll be dealing with leggy branches if you can't increase the light intensity the plant is getting.

I appreciate you acknowledging my contributions - thanks.

Thanks, Al. I will commence the pruning / lamenting the light situation in our home.

After this second answered question of mine and reading many more of your posts over the last few years, I was reflecting yesterday on the generous and unique way you have found to make a difference for people and make the world a little more beautiful. You are appreciated!
