Mulch:
It’s old, but classic. It accomplish two important goals for your plants: they help them retain water and stay warm. In addition, they suppress the growth of weeds in garden beds, making it easier for you to maintain them over time. Spread a layer of wood chips over the garden in spring to get it looking clean, sharp, and beautiful, and repeat in fall to protect your plants from freezing temperatures and snow. Be aware that you may need to add nitrogen fertilizer to supply the needs of your plants, and make sure to churn up or remove old mulch before remulching so your plants aren’t buried.
2. Composting material:
It contain a great deal of carbon, and they’re great for building up the soil. Just by using them as mulch, you’ll be improving the condition of your soil — but you can also add them to your compost as a carbon or “brown” layer. They’ll break down and enrich the dirt, making it that much more nutritious for the plants.
3. Fuel:
Like other wood products, wood chips can make great fuel, and they’re especially useful for fire starter and small, controlled fires. They’re also ideal for biomass reactors, which can be used to power engines in addition to providing heat.
