We got heavy frost here (near Binghamton NY, zone 5) last night too. We pulled our trees in to the laundry room even (have only 6 trees), rather than the garage (which is unheated). The trees are pretty leafy now (way earlier than most years) and have brebas on them.. I was unsure whether 27 degree air (in the garage) would be harder on the leafy trees than the temperature fluctuation (of bringing them in to the laundry room) would be. Can leafy trees with brebas deal with 27 degree nights if they don't get frost on them? In contrast it's about 67 degrees in the laundry room, so it's quite a temperature fluctuation for them.
Can any of the experts here give me advice which is the better choice for leafy trees with brebas, when the temperature will fall below freezing and a frost is coming?
a) garage (cold air, say 27 degrees, but out of the frost), or
b) indoors (warmer air, 67 degrees, but subjects the trees to wider temperature swing). (Unfortunately none of the indoor places I have will get much sun, so just keeping them indoors until the cold nights have passed doesn't seem a good option... that'd mean leaving them in low light for 5 days).
They're calling for another 3 or 4 nights of frost and below freezing temperatures here, so advice from the experts will be much appreciated! In past years I'd have just pulled them into the garage, but I've never had trees this leafy and far along this early in the year, with frost and freezing still coming... the trees are at least 3 or 4 weeks ahead compared with most years...
