If you are looking for a gardening tip on how to keep small pests from eating your plants then this article will provide you with a helpful method. All you have to do is sprinkle some fresh coffee grounds around your plants that are affected by these pests. Even though this method might sound odd, it is actually quite effective because coffee grounds act as natural barriers to any hungry pest that passes by.
However, take into consideration that fresh coffee grounds are very acidic and as a result, not all plants will react well to them. So, if you think this may effect your plants negatively then consider sprinkling them in moderation. Alternatively, you can use used coffee grounds instead of fresh ones. The reason for this is that used coffee grounds are more or less neutral in pH, which means they won’t cause excess acidity in your soil.
