Martins Mushroom Compost, a by-product of the Australian mushroom growing industry, is a nutrient-rich organic material perfect for home gardens. With slow-release nutrients, it improves soil structure and reduces compaction, while also aiding in water retention and drainage. Ideal for a variety of plants and soils, this eco-friendly compost can be used as a soil conditioner or mulch to promote healthy growth. Note that it may not be suitable for certain native plants or acid-loving varieties such as azaleas, camellias, and rhododendrons.
