What's 90% or 30 times more effective than a honey bee at the act of pollination? Why it's the Orchard Mason Bee. With the planting of the pear trees this spring out front and my planned planting of more as I replace a beetle infested pine tree I thought it would be a good idea to start attracting and retaining some early pollinating bees. I built two Mason Bee houses out of an 8' redwood 2X6, that I purchased for $8, and some left over 1X6 from previous projects. It took me a few hours last night to put them together and hang them. Most of the time was drilling the holes. My elbow was quite sore after that. The boxes are easy to build and inexpensive and provide a place for the bees to lay their eggs before sealing the holes with mud. The holes must be 5/16" in diameter and you want to hang the boxes on the east side of a building or fence to catch the morning sun yet not get too much afternoon sun. You also need to provide some mud. There's plenty of information on the web concerning making the houses and attracting the bees. One great thing about the houses is that you can hang them now where you can catch have the bees use your house then move them to another location in late Novemeber. I'll be putting some up at friends in hopes of getting use there if my 2 at my place do not get used. I'm going to be getting some free redwood 4X6 and will be making quite a few more to use and give away. If you want one or two and can pick it up in the Roseville area let me know.
