| I have phals, and have not had any problems (so far) with the light/temperature changes. I would be careful about submerging the whole plant at this time of year (in the UK) as they take much longer to dry.
I have my phals (and other orchids) on a very broad windowsills and also have gas central heating. As you have already moved them closer to your windows I would suggest you keep an eye on your plants and tackle each problem (if any) individually as it arises.
I find that the time between watering, for all the orchids I have, has now doubled (in some cases trebled) from the summer regime. I would suggest the skewer method as an acurate indicator of their needs. |
