Good morning polly,
Wow, so much to think about! I didn't notice any worms last season, but I didn't know what to look for. Maybe I just over looked them?? No I don't use Round up in the garden. Sometimes to clear ground of invasive weed or poison ivy. My grandchildren are in and out my gardens. I don't want to have to worry about what they touch. This is a photo one SIB, maybe you can see the holes. I'll see what else I have for pic's. I didn't take many because they looked awful.
Thanks for your help.
