Answer: Coffee grounds are a good organic source of nitrogen. Yes, they can be spread around all plants. They decompose slowly, adding a steady supply of nitrogen and are unlikely to burn plant roots. It's also a good way to reduce the amount of waste sent to the landfills. You can also put them in a compost pile. Many of the "coffee bars" will save grounds for you if you want more of them. You can simply spread a half inch of coffee grounds over your veggie garden and dig them in, then spread an additional half inch over the top of the soil after planting. Best wishes with your vegetable garden!
