I bought a few bags of cheapo top soil, dumped it into a wheelbarrow and soaked it. I stirred it up a few times over two days. I drained off the water and dumped it on a tarp. It was very clumpy and sticky. Worked it over and let it dry, then re soaked etc. I was not happy with the consistency, ie, the clumping and all. So. I got a few more bags and this time sifted them into the wheelbarrow. I did the whole procedure as before, but this time , the mix is creamy and smooth. Im on my third soak/dry and it's lookin good. The sifting removed most of the clay balls and alot of the twigs etc.
