I watched a documentary several years ago about mason bees, and it said they are better pollinators than honey bees because o the way they splat land on the lowers. Hubby used to keep bees had 5 hives at one time and an electric separator even. Mites were a problem though he had to medicate them every spring I they made it. The mason bee thing looks interesting though.
Hey I went looking for that episode and actually found it. The host website had a lot of great episodes here is the mason been one for anyone interested. Very little work involved in keeping themhttps://www.growingagreenerworld.com/solitary-bees-pollinators/
