Hi all! I have a number of phals in pots that are a bit too big. Could this cause the phals not to bloom? I have a problem with lighting (too low), but I want to know if pot size could be a factor, too. Thanks Probably the light is more a factor than anything else. Make sure you feed them occasionally too. Problem with pots too big is that you have a much much greater chance of rotting your roots. No roots = no flowers (= no plant...). And, of course, the smaller the pot the more room you have for more plants.

In addition to adequate light, most phals require a drop in night temps to
induce flowering. I've seen various figures bandied about, and I confess I have not measured, but by "feel" it seems to me that a 12-15F degree diurnal change is what does it for most of them [plus the night temps have to be down around 70F or below]. -- Kenni Judd Juno Beach Orchids http://www.jborchids.com "Sarah" wrote in message ...

It is my understanding that you can't get a phal to bloom if you keep it above 68F continuously. In fact, in Taiwan (and other places, no doubt) they take advantage of that fact to ensure blocks of plants all bloom at the same time. Dropping it below 68F for a period of time (I have no idea how long) induces flowering. I think Dr. Wang at Texas A&M has done a lot of work here. In Taiwan they have it worked out to a very exact science. I haven't seen any of the primary literature, this is from a talk that one of the graduate students here gave last month... -- Rob's Rules: http://www.msu.edu/~halgren 1) There is always room for one more orchid 2) There is always room for two more orchids 2a) See rule 1 3) When one has insufficient credit to obtain more orchids, obtain more credit LittlefrogFarm - Growing the plants Rob likes. ) |
