Coffee Grounds

Question:

Could you tell me how much coffee grounds I can add to my garden without causing damage?

Answer:

Coffee grounds have many uses in the garden. Sprinkle a few handfuls of used grounds around plants before rain or watering, for a slow-release nitrogen feed or dilute with water for a gentle, fast-acting liquid fertilizer. You can also add to compost heaps to increase the nitrogen balance. Coffee grounds are high in nitrogen but are also acidic. Small amounts of grounds shouldn't cause any problems but you should test the acidity of your soil before applying large amounts to ensure you don't make the soil too acidic for the plants you are growing. Nitrogen is very important in soil and plants tend to always need more, any excess will drain away with the rain. Therefore, again, small amounts will be beneficial but, as with anything, don't over do it.
