Landscapers Pride Mushroom Compost is a locally sourced, pasterized mushroom substrate that is blended with organic compost.
Mushroom compost is used as a soil additive for growing mediums, for both container and in-ground planting. 
Keeping your soil balanced is key for healthy plant growth; always use a conservative ratio of compost and soil to maintain a neutral pH level.
Mushroom compost should be incorporated into your existing soil at a 1/3 ratio.
