Worm Castings vs. coffe grounds?

10 years ago

Locally I have available free coffe grounds and worm castings are $10 for 18 quarts. My no till lasagna garden is around 2 years old with layers of straw, leaves and grass clippings. Soil is now very dark, loose and rich.last years plants all appeared very healthy. Worm castings were added to the rows that were direct seeded and to the transplant holes. I think I am getting enough nitrogen from grass clippings and now 10 gallons of coffe grounds per week on my 2500 sq ft garden. Lots of worms under the mulch, my question is should I buy castings again this year?

It sounds to me like your soil is in good shape and I wouldn't bother spending the money myself as I have plenty of worms doing their casting in-situ.

I think worm castings are a great way to jump start a "young" garden on its way to becoming an alive and fertile place for plants to grow. Once your garden soil has a chance to mature with regular additions of compost natural soil amendments and TCL the worms will be there working their magic and additional castings would not be needed. It sounds like from your description your garden is already there, with additional castings not needed.

In a garden where the soil has been well developed, I like to but a little worm castings in the hole before I put the plant into its home.
