Hello Clint
I find that coffee grounds are best used as a green component of making compost, especially useful at this time of the year when green waste from the garden is scarce. I have found that adding it directly to the garden is fine but if more than 2inches thick it can be hydrophobic so i gently run the how across the surface to mix it in just slightly.
Personally i wouldn’t use it a primary base for making new beds not becasue of anything to do with anything other than it’s not the ideal growing medium for vegetables. Stick to homemade compost and reserve the coffee for layering in the compost bin or top dressing garden beds.
