I was hoping someone could/would answer, but I'll go ahead and throw in my two cents. I've grown several Kohleria (and LOTS of other gesneriads) in the last 18 months. So I am slowly accumulating experience and knowledge. I've been active on the Gesneriphiles mailing list, too. I've not heard of gesneriads being affected by day length. Although stronger light typically induces more blooms. I wonder if your plant is missing some trace elements, or is pot bound and perhaps just needs some fresh soil? I also wonder if it has been afflicted by some unseen pest that is making it weak. Do you see any unusual increase in dead leaves? For me, Kohlerias go dormant this time of year. And in fact about 75% of mine appear to be in "empty" pots right now. I've been considering digging the rhizomes and sending them to Dell for the BX but I worry that it's gotten too cold for them (was 28 deg F here this morning). I hope someone smarter responds. Kohlerias are not my favorite. They get far too big for a windowsill! :-) Dennis in Cincinnati, Ohio, USA On Thu, Nov 10, 2011 at 1:51 PM, Brian Whyer <brian.whyer@btinternet.com>wrote: > Can someone tell me if this plant is affected by daylength?
