By Darcy Larum, Landscape Designer Poor soil can describe a range of conditions. It can mean compacted and hard pan soil, soil with excessive clay, extremely sandy soil, dead and nutrient depleted soil, soil with high salt or chalk, rocky soil, and soil with extremely high or low pH. You can experience just one of these soil issues or a combination of them. Most of the time, these soil conditions are not noticed until you start digging holes for new plants, or even after planting and they do not perform well. Bad soil can restrict the water and nutrient uptake of plants, as well as restrict the root development causing plants to yellow, wilt, dry up be stunted and even die. Fortunately, poor soils can be amended with soil conditioners. What is soil conditioner? This article will answer that question and explain how to use soil conditioner in the garden.
