Hello everyone, I'm very new to gardening so I apologize for any silly questions.
I have a 10x10 raised bed that my grandfather has been using for a while, but I'm taking it over from now on. The soil on top is a little rocky, but decent. However, about 6 inches down is just clay, and the further I go down, the harder it is. My questions are:
1) Should I dig the entire garden out and mix in compost/peat moss, then fill it back in? Or should I just try digging down to the clay and mixing as I go? Also I'm not sure if I should mix the clay in with the rest of the soil or discard it.
2) Should I just mix all the soil components together evenly, or should I finish the bed off with something like compost on top?
3) How deep should I dig the clay out?
Thank you in advance for any help!
