Timberline Soil Conditioner is made from aged pine bark fines and soil additives, making it especially effective for vegetable and flower gardens dealing with sandy or heavy clay soils. It helps soil retain moisture so you water less often, while also aerating compacted ground for better drainage and root growth. Each bag covers 1.5 cubic feet, making it easy to calculate how much you need for any size project.
This product works equally well mixed into native soil in garden beds or incorporated into container and potting mixes. As the aged pine bark breaks down over time, it continues to improve soil structure and add organic matter, making it a long-term investment in the health of your plantings.
