Good point Jim. I may have been premature. I drove that stretch again yesterday, and I did see some blooms starting to pop out on the almonds. Very few, but some. So the bloom is starting right now it appears.
Also, here's a pic of some hives still in the staging process.
So it looks like I caught them in the process of delivery and setup of the hives.
Another note: there really isn't anything else for the bees to target in these large commercial Ag areas right now - nothing else is blooming, that I saw.
