  1. Absolutely, but not on it’s own. I use hundreds of lbs of spent coffee grounds as an organic amendment. I make my own potting soil too.
    Coffee grounds once passed through red worms, worm casting/ potting soil.
    Mildly acidic to neutral, these go a long way in improving my clay soil. Earth worms literally work them right in the ground.
    Solely to start seedlings? Not so good. I tried this with about 6 seedling varieties of plants.
    None thrived, tomatoes spindly, most, if they did germinate developed rot at the base of them stem.
    Fungal disease
    Coffee grounds, however, outside, or in vermiculture, once passed through red worms worm/work wonders.

  2. In Vietnam, coffee residue or coffee waste (ground coffee powder after being brewed) is used for making bio-fertilizers. Local people also use coffee pulps (the outer skins of coffee fruits) to make organic fertilizer to feed coffee trees or other vegetables, etc. It works well.

  3. No, but coffee grounds do contain nutrients for plants.
    Add coffee grounds to your compost pile, or till them into your garden soil. Coffee can’t replace soil, but it makes a good additive.
    On the other hand, if you are interested in growing your own mushrooms, coffee grounds work great. Mushrooms grow on cellulose material rather than in soil, and coffee grounds fit the bill. That why, in nature, you see them growing on old logs, tree trunks, and rotting plants.
