George, to the forum. I'm one of those who mostly take up space because I'm still learning. (Maybe humorous space, like Tim. I can always hope!)
At any rate, I really just wanted to say everyone on here has killed a few plants. Ideally, we learn what we did to cause its death and then we avoid the same mistake in the future. OK, maybe some of us repeat the course a time or two before graduating, but you get my general idea. You seem to know the right things to do.
I love the Enc. tampensis! I have a cross of it (with E. alatus) and, if it decides it can grow with me, maybe I'll go for it down the road.
