I've had a pretty nice D. mexicana, about 8" diameter, for about three years now. This is the start of its third growing season. The first year, I bought it from a nursery who themselves had only received it about a month previous. Therefore, it had only just began too root itself and throw a vine. When it finally went dormant that season, I pruned off the vine.
Its second season, it threw a fantastic vine, nearly 30' tall! It flowered and stayed green for almost the entire year. In fact, the vine (not the leaves) never seamed to totally die back. As an experiment, this year, I didn't prune the vine. Now, as spring has truly sprung, there is new growth forming about 10' up the old vine!
I am looking very much forward to seeing how this all transpires this season. If each of the new growth spots throw out 20' of vine, my porch will be consumed!
So, for all of you out there lucky enough to have one of these guys, how do you deal with your vines? Do you cut 'em or leave 'em? Any correlation between pruning and caudex growth?
