UCG Ratio In New Raised Beds
I'm adding some new raised beds to my vegetable garden this fall and have been collecting and drying hundreds of pounds of used coffee grounds to use in them. I was planning to use a 2:2:1 ratio of coco coir, compost, and dried coffee grounds. Nothing will be planted in the beds until next spring and they'll sit for three or four months under snow.
After scouring the forums I've become concerned that the proportion of coffee grounds may be too high or that I should compost the grounds first.
So, are my ratios okay or would it be better to just add the grounds to my compost and use a 1:1 ratio of compost to coco coir?
