Dracaena marginata Advice
I've owned houseplants for 15+ years, but have only started getting serious about it in the past few months... Which means I'm very quickly learning what I've been doing wrong all this time. :)
One of my "walking wounded" is a Dracaena marginata. I've had it for a number of years; it's currently been in the same 8-inch pot for at least 3-4 years, and one of the trunks died a couple years back. The rest of the plant is, well, kinda scraggly:
At this point, I think I have it way overpotted, and have probably been alternately over- and under-watering it. I also suspect humidity problems during the winter. I was planning to remedy by snipping off the top and trying to root it, and at the same time, prune the main trunk down to a few inches from the soil line. My thought was, if the trunk sprouted new growth, I'd re-pot it (and probably pot it down); otherwise, I'd hopefully have a new plant from the top to start fresh with.
When I went to check on it today, though, I got a surprise:
It's a little blurry, but that green spike in the middle of the picture is new growth coming from the root of the trunk!
So, now I'm in a quandary. I'd like to help that sprout along, but what's the best way to do it? Should I go ahead with my original plan? Delay until the sprout gets bigger? Re-pot ASAP? And does my original diagnosis/plan make sense in the first place, even?
Anyone have suggestions on this?...
