I'm on Mars. Just playing. I'm in southern california. We import our soil from Mars. Very true, the soil here is mostly clay. I have (over the last 3 years) been trying to lighten up the soil. I've added compost, leaves, organic matter from the kitchen (coffee grounds, peanut shells, egg shells and vegetable ends and peels. The soil is very bad. I take all the leaves and mix them it and the soil. Its has gotten better but far from what I'd consider good. I think the solution is to move. I have been going to planting in containers instead of the ground. Thank for your response.
