So I recently bought a couple 40lb bags of organic top soil. Is this better or worse than potting soil? The top soil seemed more compact than potting soil, but I can always aerate it.
Mix in a bit of sand to make it drain better. What is sold as ´potting soil´ is usually nearly all peat. Organic top soil is going to have more nutrients. I get best results fom a nutritous, well draining mix. I add horse shit, sand, volcanic rock and garden compost to a peat based substrate. And use a comfrey based liquid fert. We all have to make best use of what we can get.
i've had good experience with it. I germed my seed in them. The soil is very light...of course I live in a different continent so...
