5, The coffee ground is a great source of nitrogen

Plants need nitrogen for survival. As humans breath in oxygen, nitrogen helps plants make their own food without depending on other beings. But how do you get nitrogen into the soil? Some use chemical fertilizers for quick nitrogen fixation. But that only ends up destroying your soil fertility.

Let nature help you. Consider using coffee grounds which are rich in nitrogen, tannic acids, and other nutrients. Your plants need these nutrients to stay healthy. And we all know that a healthy plant is healthy for consumption as well. This practice is part of sustainable gardening.
