As far as temps go, if not for a few cold nights, it's been a very warm autumn. Last year we had snow on 17 Nov, this year it's warm and sunny. Wish I could have left mine out this long but the weather's just too unstable. Until April...
Luckily I live on the second floor of an apartment complex that sits on top of a hill! The orchids have gotten two weekends of torrential rain, so I think they're pretty well flushed of accumulated fertilizers.
