Out of five miltoniopsis, all but one are throwing new fans. Some of those were already present at the time of purchase, but some are more recent, which makes me happy. I'm still wprried about them in the summer though.
By the way, I accidently damaged one new fan. It was bent because it was caught under roots. In trying to help it out, I broke it off about half way. Then I took a knife to cut two healthy roots off to make room for it to grow.
I should have done that first as that could have resulted just a little root loss instead of losing a little bit of roots and half the new fan.
Oh, well... I still have lots more.
The pictures are of different plants.
Red one, yellow one, white one ( sorry about the dark picture), and red with white edge/yellow center (one I chopped off the new fan half way, you can see the one at the bottom right in the pic)
