Another benefit of mulch is that once natural mulch decays, it can be used as fertilizer as it provides plant nutrients that are beneficial to the plant. Certain materials of mulch are used to repel insects that are quite harmful to the plants. Mulch also speeds up the process of photosynthesis by upward reflection of the sunlight to the plants. Lawn care has also become a decorative element in landscaping.
