Re: [apple-crop] weather
Mid-80s here in Southern California, high-chill apples still do fine in the spring. Enjoy it while you can.

But we could go to -10 anytime.

Re: [apple-crop] weather
The trees cant be fooled. They won't break dormancy until the requisite number of dormant days have passed. If it was 60°+ for weeks in late February, I'd be concerned. > On Dec 11, 2015, at 8:17 AM, Arthur Kelly wrote: > > Should I be worried about this weather?

Thanks Jon ! We can study this over the holiday as it gets even WARMER! Really, this will be good to understand. Have a nice holiday.

Re: [apple-crop] weather
My thoughts, everyone talks about the weather but no one ever does anything about it. In reality we cannot do anything and that may be the best thing to do - nothing. Certainly would not be out pruning any trees. Sent from my iPad On Dec 23, 2015, at 4:36 PM, Franklyn Carlson mailto:fcarl...@carlsonorchards.com>> wrote: Thanks Jon !

Re: [apple-crop] weather
Jon, that was an articulate and correct explanation of the current thought on chilling units. However, I should point out that it's full of holes when it comes to apples, such as how "low chill" Anna and Dorset Golden (Bahamas) grow just fine in zone 4 upstate New York, where they blossom in April along with the other apples instead of in January like they do here. Or why on our 100 chilling hours we're still able to grow "high chill" super-hardy apples like Wealthy and Black Oxford, which incidentally blossom about the same time they do up north, even though it may have been 100 degrees here for weeks. I'd say day length may have something to do with it, but even that doesn't answer all the questions. I just assure clients that "the tree knows what to do" and to plant whatever apple variety they want, and to ignore the chilling hours. Wish I could say the same for peaches (the disease-ridden bug-infested squishy-fruited chilling hour monkeys).

Re: [apple-crop] weather
I e-mailed the contact at getchill.net, asking him for references for the models if you ran the app on his site. His response below, good reading, particularly if you are not ready yet to settle for "42." :-) * Hi Jon, Here are some of the references I used to compute the chill accumulation for each model. Hope this is what you are looking for. I personally only use the below 45 model. There isn't a lot of information about ratings for fruit trees using the dynamic model. Utah models give wacky results in my warm winter climate (San Diego). A reference for Utah, Positive Utah, and Dynamic models. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3077742/ A guide to calculate chill portions using the dynamic model. http://ucanr.edu/sites/fruittree/How-to_Guides/Dynamic_Model_-_Chill_Accumulation/ Some fruit trees rated in chill portions using the dynamic model. http://fruitsandnuts.ucdavis.edu/Weather_Services/chilling_accumulation_models/CropChillReq/ Here is the correct link for Utah, Positive Utah, and Dynamic models. I accidentally pasted the wrong one above. http://agis.ucdavis.edu/publications/2009/Sensitivity%20of%20winter%20chill%20models%20for%20fruit%20and%20nut%20trees%20to%20climatic%20changes%20expected%20in%20California's%20Central%20Valley.pdf Thanks, Tom On Wed, Dec 23, 2015 at 6:17 PM, Kevin Hauser wrote: > Jon, that was an articulate and correct explanation of the current thought > on chilling units.
