March is the beginning of repotting in earnest. If your media has broken down or your plant has overgrown its pot, now is a good time to start repotting. Look for new shoots and new roots as a signal of the upcoming growing season.
Also, the bugs are back so take precautions now and start an insecticide regimen to take care of them.
Hope you are having a wonderful time enjoying all those spring flowers popping up on your orchids. Nobile dendrobiums are flowering at my house and my Phalaenopsis are spiking, too.
