How do I treat a Phcal.

[D&S Mabel]

My wife fell in love with a Phcal. Kryptonite 'Ursula" and towed it home from Lowe's this past winter. Besides the blooms, which were very nice, the plant looked pathetic and I didn't have the heart to tell her that it wouldn't make it much past blooming.

Eight months later, I have a little monster on my hands.



In the middle of the pot is what it came as (although it had no leaves at the time) and to the right is new growth. This thing is really stuffed in the pot ( a 4") but doing well, with very healthy roots. It's starting to creep over the edge of the pot, so time to repot, I think.

My question is, how do I treat this plant? It is looking more and more like Phais but it appears to be in spag. with no soil. It's doing well in low light.

Also, what's the "cal" in Phcal?

Thanks!
