Nice looking garden Jim , it will be quite awhile before I can get mine in up here in Maine.I have planted a few tomato seeds in the house to get a head start on things , that way I can get the different varieties I like.I plant mine deep also it seems to work fine for me. Your tiller did a fine job of breaking up that new sod , you would have had a hard time to get it like that with a dics harrow for sure.I would like to have some sand on my property like yours.I know what you mean about gardens in our younger years,what a drag that was,now I love it.I grow way more than I need , just give it away.
Enjoy,
Herb
