i mix a bit of water with mine if i'm in a pinch and can't mix the eco earth with something else. that takes away the dry/dusty part. Thing i don't like with that though is it dries out faster than peat or soil, and then it shrinks and forms a hard brick you can't do much with but throw it over the balcony rail and watch it explode on the patioEco earth is kinda dry and dusty, I dont care for the consistency so I moved away from it some time ago. I do like potting soil, and jungle mix, which is fir peat but it does have bark in it. You can even get splinters running your fingers through it, which some folks may not like.. But it feels like and looks like forest floor to me, and mixes well with both clay and potting soil. I think the bits of bark seperate the soil and allow moisture to spread well, plus it looks good. Thats some fine looking dirt.
Never had a problem with eco-earth if i mixed it with soil or peat.
