We hit 15 degrees last Saturday morning and may have gotten some damage.  We 
were at silver tip then on apples and swollen bud on peaches.  Cool weather, 
wet weather since has slowed development.

  I'm jealous, well sort of.

  Fully dormant here at 4000 ft Montana. Skiff of snow last night with a low of 
24°, high today in the 40s.

  Forecast is for lows in the teens. Plenty of time left here for pruning.

Heading for a record early budbreak in Quebec. Old record of April 9th 
established in 1981 will be beaten by about 2-3 days with the help of the 
temperature in the higher 70's forecasted for the coming days. That's 2-3 WEEKS 
ahead of our 30 year average for green tip.

Of course pruning is not finished and sprayers are not ready.

No Easter Holiday up here this year!

Re: Apple-Crop: degree days and apple bloom prediction

In Michigan we have used approximately 284 DD42 from March 1 as the start
point for king bloom on Macs. This is in our Michigan State University Fruit
Management guide E-154, from a chart originally prepared by Phil Schwallier
of MSU.  This is based on pre-1990 weather data in the Grand Rapids area of
Michigan.

In recent years we have been getting more DD before March 1...so ignoring
what happens before Mar 1 is now becoming problematic.  So, I generally add
on 25 DD42 to the total and use a target of 310 DD42 from January 1 as the
start point for king bloom for Macs.Not sure if this works for your
area.  1/2" green is approx 205 DD42 from March 1, or 230 DD42 from January
1 with my fudge factor.

RE: Apple-Crop: degree days and apple bloom prediction

[alan surprenant]

good morning. my orchard is the berkshires of western massachusetts, elavation 
1300ft.  my past records of 20 years show 18 to 20 days from greentip to full 
bloom on apples (given varietal differences-i don't grow red delicious)  plums 
bloom about 2 weeks before apples, asian pears about 10 days before, reliance 
and red haven peaches about 7 days before apples. all of the above bloom has 
been at the earliest 25 days away (ie. april 24th) to start.

 

is green tip early for you this year (and recent years)?  our bloom dates have 
steadily gotten earlier on average. i've grown apples since 1982, and at this 
home orchard since 1990.  i hope this helps. i don't do alot with degree days 
opting to observation of the trees directly and comparing with my records. 
probably some university websites could help with degree days. both UMass 
Amherst and Cornell have good sites.

 

on a different note would you be up for a brief visit from a couple of 
fellow apple growers? my partner and i are planning to travel to visit friends 
in asheville and pittsboro, NC early next week for 12 days or so (bloom really 
isn't till early may here!). we plan on coming down the blue ridge on the way 
to asheville. i haven't been in your beautiful country since walking the 
appalachain trail in 1976.

 

best of luck this year
