It's that time of year when everyone is worried about how bloom is progressing and whether bees are active enough to get the job done. Both temperatures and bloom are off to a slow start compared to last year. According to grower and Blue Diamond Board Member, Dan Mendenhall "the weather and bee flight so far have been sporadic and peak bloom is still to come".
Given bees don't fly below specific temperatures, we used our historical in-canopy weather data to compare last February's conditions to this year's to see how their active flight hours stack up.
The following charts show 2019 vs 2018 bee activity for a North, Mid, and South Valley customer site. The vertical bars represent daily bee hours - blue for 2018, and orange for 2019, with the curved lines showing cumulative bee hours.
We're well behind this time last year, but with the prolonged bloom, this recent warming trend may help align it with more active bee hours to get those pollination results everyone needs.
