| A neighbour gave me a bag of coffee grounds and told me she heard that they are great for improving garden soil. How do I use it and are there some plants it will harm? |
| Coffee grounds are an excellent source of nitrogen, and will acidify soil to a small degree. You can compost them or you can just broadcast them onto the soil. Either way, they're beneficial to garden soil, and will attract red worms, which will help break down organic matter. Coffee grounds, used in moderation, should not harm any of your plants. |
