Choosing the right mulch for your garden can significantly impact plant health and garden aesthetics. The best mulch depends on factors such as climate, soil type, and plant needs. This guide will help you understand different mulch types and how to select the best one for your garden.
What Is Mulch and Why Is It Important?
Mulch is a layer of material applied to the surface of the soil. It serves several purposes:
- Moisture Retention: Mulch helps retain soil moisture by reducing evaporation.
- Weed Suppression: It prevents weed growth by blocking sunlight.
- Temperature Regulation: Mulch insulates the soil, keeping it cooler in summer and warmer in winter.
- Soil Improvement: Organic mulches decompose over time, enriching the soil.
