I kept track of and recorded in my log the blossom progress of each of my bearing apple trees the last two blooms, and took photos of the bee swarms at the trees. Last year, the trees came through a gruelingly cold winter. This year, they came through a mild one. Across the board, they are blooming just two days earlier this year than last. The biggest difference I see actually is in the composition of the pollinating bee swarms. There are way, way, way more honey bees and bumblebees here this year. The mason bee swarm density is about the same as last year, as is the hummingbird visitation regularity.
