For 11 years 1985-1995 I kept a looseleaf notebook journal.
On bloom time of most every plant…
I did it because I had lots of honeybees and I’d know when to expect orchard blooms, when to expect dandelions, tree blooms, pollen sources, and the main honeyflows. Also, by looking at the pollen, know what the bees were currently working on.
Interesting…but took quite a bit of time…I don’t have those records anymore…but some of it I still remember.
