Orchids grow but don't rebloom.
I have Cymbidiums, Phalaenopsis and Miltassia. They were all blooming when I bought them, between 2 and 3 years ago so they are definitely blooing size. They grow well, healthy, green, new roots and shoots etc. They get bright, indirect light in an unheated sun room. Temperature in winter is 65-70 by day, and 50-55 at night. In summer it's pretty much whatever the outside temp is, generally 80 day and 60-65 night. There is good air circulation, open windows in summer and ceiling fan very low in winter. I put the Cymbs outside in summer, in bright shade with a little morning sun but no strong sun. I must be doing something wrong, so any ideas are welcome.
