Bed prep

creister · March 10, 2015

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?

I think it will be OK since it is an organic source that takes a while to break down. I just put down a mix of coffee chaff, coffee grounds and half broken down shredded leaf compost. I will give it 2 weeks or 3 before I plant.

You always need to balance green and brown, if you have no other sources of nitrogen, best lay the coffee down, the leaves breaking down will soak it up, I doubt much will be available till it all breaks down. Tomatoes are pretty heavy feeders in my experience.
Compost alone is not really a fertilizer, more a soil amendment. I always add organic fertilizer to compost. So adding coffee grounds is adding organic fertilizer. I myself would add more anyway. Not like coffee is a super source of nitrogen.

If you have worms in your garden they will love the coffee grounds and leaves.

I was curious how much nitrogen is actually in coffee grounds. Googling it, there are many sources that suggest about 2% nitrogen by volume. For what its worth.

I went ahead and put the compost on top of the cut vetch, then put leaves, then coffee grounds, and then shredded tree trimming on top. I layered it green - brown, and the coffee grounds were stirred in with the leaves to some extent, so I think this will work out fine. Much like planting in a new lasagna bed, or planting around the edge of a compost pile.

All I know is that coffee grounds rapidly heat up the shredded leaves, indicating a high nitrogen level. And, unlike green clippings, coffee grounds keep a big pile hot for two weeks or more.
