Well I better correct my statement from this morning. After visiting some of my yards today (62*F) and finding some pollen coming in.
Looks like the grey alders have stated blooming (see picture), also some light yellow pollen in 2 yards (no pics) from either witch hazel or maple or both. I couldn't track it down because of snow in the woods and mud in the fields. If alders are blooming, real maple bloom can't be far behind and certainly only 10 days of so out.
