Trimming the roots helps to prevent overcrowding of the roots and stimulates new growth (Strawberries only). Carefully separate the roots, untangling them, and examine the plants you have. Dig a hole that is six to eight inches deep and two times as wide as the length of the roots. Partially fill the hole, firming the soil around the lower roots. Do not add soil amendments such as peat or bark. Do not use fertilizer, potting soil, or chemicals on your new plant
