It has been so cool in the last month here in Metchosin that my mason bees have almost missed the peach and nectarine blooming time.
Update–April 15: Today they were the most active i have seen them . I started putting a few cocoons out a week ago, and have warmed up some indoors by just removing their containers from the fridge and then setting the jar out in the daytime when the sun is on them. Anyway a very unusual cold start for the spring.
I have several kinds of houses placed on the South East corner of our house.
