Great Forest! I also have a few benjamina I just picked up. They are a little tall, I'm wondering how much can I reduce and how to go about doing it. Any suggestions?
I got mine from Home Depot quite a while ago. If I recall, all in one pot. I've had them in several configurations over the years. Probably will change it again when I repot. I wired a few trunks back in the day and left it on too long. I experimented with "shaving" off the wire ridges here and there, and figured I girdled the trunks, but it worked to smooth out the damage. The trees are pretty easy for me to work with.
To get yours to fill out, cut them back, pinch new growth, feed well, water as needed, and give them sunlight to their hearts content when hardened off in spring. And remember about leaf scortch. Perhaps filtered/dappled sun for a couple weeks is prudent.
I just remembered a trick that I employ. Every week or so, leaf prune the largest leaves. Pick a number based on the size of your foliage. It might be 10 leaves or it might be 30. Take the largest ones off and the remaining stored vigor should be redirected to closer in.
