Since this was my first raised bed and I planted my tomatoes today I want to be sure I have not messed up while I have time to fix anything I might have done wrong.

I built a 4x6 box and took off the turf grass and used a shovel to remove some red clay about 4 inches below the ground. Then I dug and loosened all the clay another 3-4 inches below that. I topped with 3-4 inches of leaves and then put card board on top of my leaves. I put 4 cubic bags of good topsoil and 4 cubic foot of miracle grow garden and vegetable soil, 1/2 cubic bag of black kow and 1/2 cubic bag of mushroom compost all on top of the card board. I mixed it all in watered and let sit for a few days. Today I planted my tomatoes and used mulched leaves as a mulch. After reading other forums I am concerned I did not mix enough top soil in.

Almost forgot I used fish emulsion right after planting.

Any tips, ideas etc.. welcome since this is my first attempt at gardening.
