COLD WEATHER AND ORCHIDS

So how did your orchids do during our very long streak of cold weather here in South Florida?

What has been your experience?

Since I grow outside without any greenhouse or shadehouse cold weather is always a worry.  My most sensitive orchids ---- hard cane dendrobiums, phals, and vandas ----- I protect by bringing them into my garage.  It did not get any lower than 55 in the garage. 

All of the Vandas did great! And also the Phals.

The hard cane dendrobiums have experienced the dropping of leaves ----- but not very bad.  Oddly enough, I accidentally left three of the hard cane dendrobiums outside and they experienced temps as low as 34 and they have not experienced any leaf drop.  They seem to have done better than the ones in the garage.  I cannot figure that one out?

All of my cattyleas and encyclias stayed outside.  A few yellow leaves on some of the cattyleas, but all of the encyclias just loved it.

Now the strangest.  Den aggregatum is supposed to like the cold weather.  I have five of these plants ---- two seedlings, two mature plants, and one that is sort of in between.  The seedlings did great, so did the in between one and one of the mature plants.  But one of the mature plants simply did not like the cold.  About half of the leaves turned yellow, shrivelled up, and fell off of the plant.  Has anyone else had this experience?
