A friend of mine is worried about his satsuki azaleas. His coldframe went down to 15 F last night.
The cold frame is covered so protected from wind but its not up against his house so it doesnt benefit from the radiant heat that would provide.
The pots are on the ground and they got rain before they got a little bit of snow on them.
He has alot of the same varieties I do., but my cold frame has stayed above 25F
Kazan
Hi-No-Maru
Miyu-no-Kagayaki
Benikagi
Chinzan
Some other varieties I dont remember right now
Should he be worried or do we think he will probably be ok?
