  1. Almost anything is possible. But a 2 inch layer of grounds over your entire garden would not make a great difference in any parameter important to plant growth or production other than a mild nitrogen addition.

  2. You certainly can…. I use coffee grounds by the 5 gallon bucketfuls. Literally…maybe over a ton over the last three years.
    CG can attract a lot of molds and fungi. I also just so happen to grow edible mushrooms.
    I keep CG’s away from plant stems. And, I take care bot to heavily layer them, unless I am intentionally doing so in pasteurized layering to grow mushrooms.
    This will keep your plants safer from root and stem rots.
    You can overuse them for some plants like tomatoes. Too much green growth. Potatoes are like that too.
    In my potato beds, I dig them in 4 to 5 months before planting. They rapidly decompose, leaving very friable soil for the potatoes to develop good spuds. Not too much green growth.
    Sprinkle them out, and keep them away from seedlings. Very, very good garden additions for soil building, with these two precautions.

  3. Yes.
    Coffee grounds as a heavy mulch isn’t a good option since they compact, generating a barrier that prevents air and water from passing through. Use a thin coating (half an inch, tops) of grounds on top of a bigger layer (2-4 inches) of organic materials, such as shredded bark, wood chips, or compost, to distribute grounds on soil.
