Re: [Apple-crop] low temp pruning
Here in Norfolk I plan to prune the small orchard this month- Neil Daboul _ From: apple-crop-boun...@virtualorchard.net [mailto:apple-crop-boun...@virtualorchard.net] On Behalf Of Fleming, William Sent: Wednesday, February 02, 2011 5:56 PM To: apple-crop@virtualorchard.net Subject: Re: [Apple-crop] low temp pruning Tom, all that I've ever heard is that you must let the trees reach full dormancy before pruning especially if making big flush to the trunk cuts. First week of December is almost always a safe time to start. I know some growers will tell their pruning crews that damage occurs if they prune when the temp is below a certain point but I think that's just an excuse to keep them from working when it's too cold and their productivity is impaired.

I'm thinking of mid-winter when trees are still quite dormant, but also during cold snaps later in the season. Thanks.
