My poor orchids suffer every winter. I bring them inside the house when the weather starts getting below 50 degrees and hang them from the curtain rod in the spare bedroom. This way they get a lot of light filtered by lace curtains. However, it is really easy for me to forget about them and not water them. The dry air of the heated house is hard on them too.
But, as soon as the night time temperatures begin to rise, I put them back outside where it is easy to remember to water and care for them. This past January, surprisingly, they all bloomed while still inside the house. These are some tough orchids.
As soon as the weather permitted, I hung them on the back fence in the filtered light coming through the oak tree branches. Giving them a spray with the hose is so easy to do back there. I'm still not very good at giving them fertilizer. But, they have rewarded me with a second round of blooms anyway. This round is not as full as the first blooming, but I think it is a good sign that they are getting healthier.
