Hi, I am looking for places to learn more about the orchids I am raising. I started three years ago with a phaleonopsis from my husband as a Valentine's gift and have recently expanded into some other varieties I want to learn more about. I live in MN. Here's what has been blooming all winter and also the seedlings i bought last fall. Trying to decide if I need to repot any of the seedlings. When I bought them last fall the guy at the nursery said they would not need to be repotted until spring. If I am seeing roots coming out of the bottom of the pot is that a sign to repot? That is happening in some. Thanks for any input!
