So every year I always notice a ton of millipedes in my backyard. Usually they hang around in the lawn and under and around potted plants. This year after a lot of rain, I've been noticing much more of them actually in the soil of my container plants. I was inspecting my hops plant and I noticed there must have been 50+ millipedes in the potting soil crawling around. The plant looks very healthy, so I'm hoping they aren't doing any damage, but should I be worried?
