Now that the winter chilling period is over for most of the west we can finally get a grasp on how we did. Post up your getchill (www.getchill.net) results and what state/zone you are in. Heres mine:
Outskirts of Phoenix Arizona 9a/b
Below 45 Model: 674 chill hours
Between 45 and 32 Model: 586 chill hours
Utah Model: 50 chill units
Positive Utah Model: 983 chill units
Dynamic Model: 17 chill portions
As you can see from the numbers we recieve a heavy amount of hours under 45 degrees BUT it really doesnt show in the Utah and Dynamic models because they discount our chill due to our temperatures swinging up into the 70ās often times on those same days that we see 8-10 hours below 45. This can really be seen in the Positive Utah model that doesnt discount for higher maximums and includes hours up to 50 or 55 degrees as chill. Its hard to know which model makes more sense for our unique area.
Ah, my Davis weather station is not calculating my chill hours correctly. I have to get out and move it, so it is getting 100% full sun so the solar panel is getting enough charge. Tom warned me earlier, but I didnāt get it done for this next season. Will try to work on that this weekend. But, the closest station to me is showing this:
Vista, CA up in the hills almost 1,000 ft elevation, USDA 10b/Sunset 23
Below 45 Model: 227 chill hours
Between 45 and 32 Model: 213 chill hours
Utah Model: 7 chill units
Positive Utah Model: 765 chill units
Dynamic Model: 18 chill portions
Better than last year, but still not as good as previous years where I have been well over 300 chās.
Donāt cry for me Arizonaā¦My varieties are all low-chill and well suited for my locale, except for āRoyalā apricot which is marginal. More important for me is deep soaking rains, and weāve had a few this year.
Mine are too, Clint. I do have a few āpushersā I planted, just to see how they might perform. And yes, boy those rains will make a big difference. I did have some petal drop from the hail, but things look pretty decent, fortunately. And the best part - my Minnie Royal and Royal Lee are almost evenly flowering right now. So, hereās to hoping for a decent cherry crop this year. Will see how my other cherries fare as well, but these two cherry trees are the oldest in my yard (planted in January 2011 so now on their 4th year in the ground here.)
So far my Burgundy Plum and my Nectaplum are doing fine at breaking dormacy. My only worry is my flavor grenade which has yet, except for one branch with a couple of buds breaking.
Does anyone know how things in the central valley shaped up? I hope they got a whole lot more chill than the LA basin did or they are gonna have a rough year. I recall the cherry growers doing alot of howling after the bad year last year.
Yes,mostly Nectarines,but I just put ten bare root,stone fruit trees in a hoop house in containers,a la fruitnut.
A young Flavor Grenade planted in the ground though,fruited for the first time last year(two pieces)but they were as good as any of that variety that Iāve had so far.
Iām still not up to speed on the meanings of the different models and right now go by the Between 45 and 32 category. Brady
I have been growing fruit for a long time I understand how many chill hours my fruit trees need. I am not sure what numbers count in the get chill numbers. Below,between,Utah Model,positive Utah Model or Dynamic Model. I have never seen them explained. Not sure of the numbers that count? Any help in this matter would help.

Thanks now I know. No one has ever told me the answer. That means this year I had 1198 that is almost twice the normal chill of 600. Thanks agin
