2014 Apple Blossom Development
at WSU TFREC in Wenatchee:
On Monday, April 21, 2014, the blossom
development stage was: FULL BLOOM
at 1019 blossom degree days (43F base temp.)
since Jan. 1.
Though this is 6 days ahead of the long term normal full bloom date, it is the same date as 2013 and within a day or two of the full bloom dates of 2010 and 2012. Full bloom occurred on May 6th in 2011, a very late season.
The 2014 dates for flower buds stages were:
Green Tip: March 24
Half inch green: March 28
Tight Cluster: April 4
Loose Cluster: April 9
First Pink: April 10
Full Pink: April 14
First Bloom: April 16
Full Bloom: April 21
Petal Fall: April 28
Note: Most apples, especially early blooming apples such as Gala at lower elevations around Wenatchee develop bloom stages at least a few days before this site’s prediction, which is based on the full bloom time of Red Delicious.
“Full Bloom” is set at 60% open King blossoms on the north side of a Red Delicious tree at the long term traditional site about 50 meters to the west of the WSU TFREC.
