Saving Butterflies? Now Save the Bees

I just posted a bit about planting milkweeds to help support monarch butterflies.  What about specialist bees?  These bees, often native, are like some butterflies, in that they need specific host plants.  Virginia has a high proportion of specialist bees.  For more information, read this:  http://vnps.org/specialist-bees-need-special-plants/

and go here for a list of plants to support these bees:  http://vnps.org/plants-for-specialist-bees/

Why support bees?  We need all the bees we can get for food production and for the very existence of many plants!

Colony Collapse Solved?

The cause of Colony Collapse Disorder (what's been killing the bees) may have been determined: a virus and a fungus working together to damage the bee's ability to digest food. As you know, bees are essential to gardening and our very lives- we would not have many fruits, vegetables or grains, nor would we have many plant seeds, without them! The New York Times has a great article on this at:

See my entry on pollinators for what you can do to help the bees!
Happy gardening!

Native pollinators

Mason Orchard bees

One of my favorite Christmas gifts this last year were these two bee nesting boxes-top photo (thank you Jeannie!). We all have heard of the decline in honeybees, but did you know that honeybees were not native to America and that we have a variety of native bees? Some of our native bees are non-social (or “solitary”), that is, they do not live in large communities or hives. The two nesting boxes (or blocks) are great for these non-social, cavity nesting bees. And these bees are good pollinators for your garden.

A few years ago my brother Ed built me a mason orchard bee (Osmia lignaria) nesting block out of non-treated, but rot-resistant, lumber (the second photo). I actually purchased two tubes of mason orchard bees for them. These bees are excellent pollinators for those early flowering fruit trees, like apples, peaches and pears. It might just be coincidence, but the year I got them I had a bumper crop of peaches and apples. Mason orchard bees like to have tubes of a specific diameter (1/4 to 3/8 inches in diameter). They do their early pollination, then lay eggs in the individual tubes or holes, cover with a plug of mud and are done for the year, often filling multiple tubes. These blue-black bees live for about a month and are generally gentle, rarely stinging. They do have a tendency to move on, but your bee block can be inhabited by new bees year to year. Unlike honeybees, they need no special care.

Happy gardening!
