Unlike synthetic fertilizers, coffee as a grass feed is much safer and will not harm the grass, no need to water it down or dilute it before use. It acts as a slow-release fertilizer that takes some time as it breaks down and releases nutrients slowly into the soil.
These things are great for nutrient poor lawns and lawns on clay or sandy soil. However, coffee grounds still contain some residual caffeine, which can cause harm to the micro fauna in your soil, and that's why it is not recommended to apply coffee waste directly to your lawn.
