Best Earthworm Castings Hands Down!

I’ve been growing for ten years so I like to think I know a little bit about what I’m doing. I’ve tried many different brands of earthworm castings, and Ridgeline’s is hands down the best of the bunch. What I like about it is that it’s moist and fresh without being sloppy wet and heavy. I’ve never gotten bugs from it, and no weeds have ever grown out of it— except the weeds I’m trying to grow in it! Anyway, buy it. It’s good stuff. Your plants will love it!
