If it weren't for the bumblebees, I would have no blueberries. I am always amazed when one of my plants blooms, how many different pollinators are on the blooms. The other day we were putting in a new pollinator flower bed and I kept noticing these tiny yellow jackets on the lavender I was planting. I kept thinking they were being drawn to the fragrance. I was so wrong. I switched sides on the flower bed to continue planting and while waiting for the water to percolate down the planting hole, I noticed that these bees were going into one spot under the Mountain Mint. I pulled back the stems and lo and behold, they were going into the ground. I was blocking their entrance when I was on the other side of the bed. Lucky they didn't nail me! My point is that the bees need areas of dirt to burrow for their nests. We cover everything with mulch (we are obsessed with mulch in America) and that makes it difficult for them to find spots to make nests.
