Encouraging worms without a bin
I love the idea of a worm bin, and I understand the benefits.
But I have acres of land I want to improve. I have sandy soil, with some loam in some areas. And I have a good supply of manure. We also compost anything we can from our household.
How do I encourage the worms to set up shop and stick around without a bin?
I found my first few "nightcrawlers" (These are europeans, which aren't actually a nightcrawler and closer related to red wigglers, from what I understand). They are in a flower bed I heavily composted last year and planted strawberries in. I assume they came with the berries because there just isn't a ton of good soil around for these guys to be hiding out in. You can imagine how excited I was to find them in that bed!!
I got 2 pounds each of red wigglers and euopeans from a local compost business. I put handfuls in various areas where I've piled on 2-3 feet of manure from goats, chickens, and horses. I made sure the manure was damp, but not soaked.
The worms all seem alive and active. But they haven't moved in the last week or so. What else should I be doing? I'm hoping these guys will move in, spread out, stay a while, and work all this manure into the sand!
Thanks for any and all help!
