WANTED: Bees and wasps
I have become intrigued by all of the bees and wasps in my garden. I am convinced that they are keeping the level of aphids and caterpillars down so that I do not have to spray most things (cucumber beetles and melon worms being the exceptions). I grow bronze fennel, butterfly weed, several varieties of sage, mint, Honeysuckle, lantana and Verbena bonariensis to attract them (and of course the Goldfinches, humming birds and butterflies). I have also planted Clethra, Mountain Mint(Pycnanthemum) and a white Joe Pye Weed specifically because I have seen them covered by solitary bees and small wasps at the North Carolina botanical garden and other places. These 3 plants have been a disappointment in my garden in that I rarely have seen either bees/wasps nor butterflies on them when nearby sage and fennel plants were practically covered. Can anyone suggest why these plants are not bee & wasp attractors in my garden?
