Over the last few years when I've purchased manure at the store instead of delivery I've usually gone for the bag of Scotts Humus & Manure because I noticed it came loaded with earthworms. There were dozens , if not hundreds, of worms per bag. Even when I would store the bags in the basement for my winter planting they would be quite happy and content in there. The other day I bought two new bags and this time not a single worm. So I contacted Scotts to ask why they stopped adding the worms. They told me they have never added earthworms to any of their products and that worms should not have survived the sterilization process. I was quite shocked by this since every bag I've purchased until now as had tons of worms in them. Has anyone else had a similar experience?
That is strange. Now I'm curious. What have you found out since; if anything? I've also used bagged humus & manure, but I don't remember the brand. Now that I have 2 rabbits & a friend with 2 horses, I no longer have to buy manure.
Perhaps, you could grow your own worms by leaving some bags on the ground? I pile the rabbit poo up in a corner raised bed that's slightly shaded (or "shady"--our city has a no-compost ordinance--lol); along with eggshells, coffee grounds, tea bags, & banana peels; cover it up with leaves & pine needles for camoflauge; & always find a lot of nightcrawlers when I turn the pile. : )
