Our "study" rows, 2 average rows in which I am documenting the progression of bloom. Top photo taken 3/1/2013, bottom photo taken today, 3/3/2013. I would say this orchard is in "full bloom". A few petals are beginning to fall from the Nonpareil, but there are also a few buds that have not yet opened.   

Recently we have had ideal conditions for pollenation. Today turned slightly cooler and overcast, but the temperature was still plenty warm for the bees (high 60's) and they were very active. The forecast this coming week includes rain followed by cold air.  March can be a stressful month due to frost threats.  However, we have had a favorable start.
