What impact does mulch have on a garden?

Mulch plays a crucial role in promoting a healthy garden ecosystem, primarily by conserving moisture in the soil and suppressing the growth of weeds. By covering the soil surface, mulch creates a barrier that reduces evaporation, allowing water to remain in the soil for a longer period. This is especially beneficial in hot or dry conditions, where moisture conservation can significantly reduce the need for frequent watering.

Additionally, mulch creates an unfavorable environment for weed seeds to germinate by blocking sunlight and physically inhibiting their growth. This suppression of weeds means less competition for nutrients, water, and sunlight among the plants in the garden, leading to healthier and more vigorous plant growth.

Thus, the overall impact of mulch is beneficial, making it an essential practice in landscape management to enhance garden health and sustainability.
