As spring weather warms the soil, and recent rainfall a blessing, here is a reminder of how valuable mulching can be in the garden. The benefits of mulch depend on the material used and depth to which it is applied. In general, mulching minimizes evaporation of water from the soil surface, reducing irrigation need by around 50%. It helps stabilize soil moisture levels, thereby improving vegetable quality and encouraging the beneficial activity of soil organisms. Some of the more common mulch materials include small grain straw, wood or bark chips, grass clippings and black plastic(weed mat). Mulching helps reduce soil compaction forces from rain and traffic. And if organic material is used, the mulch can be later plowed into the garden as a soil amendment. Mulching can cool or warm soil temperatures, and can also aid in weed control.
