the soil is very bad, and I was planning to dig in about 2 gallons of used coffee grounds where I am going to plant potatoes. Would it be good for the potatoes, or harm them? Or should I put them elsewhere?

Potatoes like a sweet or basic (high pH ) soil so if your soil is acidic coffe ground would help. More improtant would be a loose thilth ie a peat or perhaps a sandy soil. If your soil is a heave, thight, or clay soil the you need to work in a lot of humas or creat raized beds, the potatoes will not form large spuds in a tight soil.

I have often been advised to put coffee grounds in a garden - flower or vegetable… they are slightly alkaline, I believe, and help ’sweeten’ the soil.

that woulde be a really cool experiment, i think they’d grow faster and have more colour due to the caffein. try it and see (and if you could e-mail the results, i’d really like to know!)
