You're right about needing dry soil. Till first to eliminate clods. The first day using it I added chicken wire, held on with tie wire. The chicken wire worked fine but I wanted even smaller rocks, so I tried hardware cloth, with 1/2" openings, and that worked perfect for me. I also learned to wire the sides and back of the basket. The best advice, though, is to do it on a windy day, with the wind blowing away from your house. I just tilled for a winter garden today, brought up a ton or rocks. So next week I'll be sifting the rocks again. Every season the garden gets better and better. Hopefully someday the rocks will have disappeared entirely.
