Ok, so I was so inspired by you folks prepping your beds in advance, that I went out this morning and started clearing a section where I've been thinking about doing an Iris labyrinth. Luckily, I saw the yellow jackets coming out of a crack in the soil before I disturbed where they are. They will often utilize old gopher burrows, which is probably where the crack connects. I'll have to wait until tonight when they're all in bed to nail them... but it changed my plans for today.... Just as well... it was 90 degrees an hour ago.
