Just talked to this fellow about his castings. It sounds like it's all tested & certified Organic. The costs are up there, but I'll likely be mixing it in with my regular compost & adding it to the planting sites. I'm thinking of getting 5 yards. What I don't use on the new patch, will go towards the older patch that we're resting for the next 2 years. If you think what a small 10# bag costs, then the cost really isn't that bad. Give them a call if your interested.
