Millipedes ate my peas!
Two years ago I grew the best sugar snap peas. The next year, millipedes ate them all before sprouting. This year the same thing. Virtually every pea was being attacked by hordes of tiny millipedes, tunneling right into the pea and consuming the root too. In desperation I dug up the rows and pushed the doomed peas off to the side. I then refilled the resulting furrow with potting soil and replanted. I reasoned that the potting soil would be free of pests. In retrospect I realize that was likely silly. In any case, the replanting has worked quite well and I have a solid stand of peas. I figure the first planting attracted the bulk of the millipedes present, and they were content to continue eating the old peas pushed off to the side. That left the new planting free of millipedes. So I'm thinking next year I might just make a sacrificial planting off to the side a couple weeks before the real planting. That will distract the little buggers long enough for the real planting to take hold.
Don't let anybody tell you that millipedes only eat dead organic matter, They definitely prey on germinating peas.
