Benefits of Mulching
Moisture Retention
Mulch reduces water evaporation, keeping soil moist longer and reducing watering needs by up to 50%.
Weed Suppression
A 2-3 inch layer blocks sunlight, preventing most weeds from germinating and growing.
Temperature Control
Mulch insulates soil, keeping roots cooler in summer and warmer in winter.
Soil Improvement
Organic mulches decompose over time, adding nutrients and improving soil structure.
