I have a couple decently-sized catts that suffered in the fall because I was busy being a grad student and not as busy being an orchid mom.

Their p-bulbs are back in good shape and both have put out new roots -- however, they had a lot of root die-off and I think they can (should) be potted down. One is a C. brabantiae and the other is a Slc. Dream Catcher 'Sparkler' x C. amethystoglossa 'Aloha'. Both have new growths, one a bit over an inch tall and one, oh, 3/4" tall. When I grew orchids previously, I habitually repotted only in the spring, usually late spring, and would do them all at once, but this time around I'm trying to attend better to the needs of individual plants. . . so, I
think this would be an appropriate time to repot, right? Even though it's basically the dead of winter?
Thanks, as always, for all advice,
Victoria
