Thadani说：“混合肥料可以提供多种营养，你也可以用家里的有机垃圾自制。”
Compost adds a lot of nutrients, and can be made easily with organic household waste.
对于花坛或培养基而言最好是2 ~ 4英寸厚的有机养料层，诸如松树皮护根或混合肥料。
For beds incorporate a 2 - to 4-inch layer of organic matter such as pine bark mulch or compost.
你也可以将混合肥料（已腐烂的有机混合物---译者注）用作蔬菜和花园的覆盖物或者肥料。
You can turn compost into mulch or fertilizer for your vegetable or flower garden.
