Bed prep

[creister]

I have yet to get most of my beds prepped and will plant out this weekend. I had originally planned to do it two or three weeks earlier, but weather didn't allow me to do that.

My beds are 50 sq. feet. I have a cover crop of hairy vetch that I will cut and lay down cover it with compost and some corn meal, shredded leaves and shredded tree trimmings on top. I will amend each planting hole. I use no till and didn't fertilize after last year.

My question is this, I was going to also layer in copious amounts of coffee grounds either between the leaves and soil, or between the leaves and tree trimmings. At this late stage, should I even put in coffee grounds? I am worried about excess nitrogen and getting big green leafy plants with no tomatoes. Or will the breakdown and release of nutrients be slow enough to feed but not over feed?
