Here are the key reasons mulching is critically important in our local climate:

• Moisture retention and water conservation — Our clay soils absorb water very slowly (often just 0.10 inches per hour), leading to runoff and overwatering issues, while scorching summers cause rapid evaporation. A proper 2-4 inch layer of mulch dramatically reduces water loss, keeps soil evenly moist, and cuts irrigation needs—vital during droughts and for water-wise landscapes.

• Weed suppression — Mulch blocks sunlight from weed seeds, preventing them from germinating and reducing the need for constant weeding or herbicides.

• Soil temperature regulation — It insulates roots from extreme heat (keeping soil cooler in summer) and protects against freeze damage in winter, promoting healthier plant growth year-round.

• Soil improvement over time — Organic mulches (like hardwood bark, native shredded mulch, or composted materials) break down gradually, adding nutrients, improving structure in our dense clay, enhancing drainage, and boosting microbial activity for better root development.

• Erosion control and aesthetics — It prevents soil compaction, reduces erosion from wind/rain, and gives beds a clean, polished look that boosts curb appeal.
