Answer: Mulching over bare earth between your plants will help suppress weeds, slow water evaporation, moderate soil temperatures and provide some nutrients to plants as it breaks down. About the only time mulch might be detrimental to plants is if it is placed against the stems of plants. It should be kept about an inch away from trunks and stems. If it is too close it can hold moisture up against the plant and cause rot. Hope this answers your question.
