Soil conditioner is excellent for starting new flower beds, shrubs, and trees. It also is great for potting plants. This product consists of 75% leaf compost, 15% sand, and 10% processed pine. It does not have dirt in it, which is the main difference between soil conditioner and garden mix. Soil conditioner will need to be tilled into existing soil if going DEEPER than 6 inches due to the fact it does not have dirt.
