Wedge-shaped pieces of solid peat, saturated with water, were placed at the bottom of a planting hole to supply water to the roots during the early stages of growth and prevent dessiccation during severe drought conditions. The survival of trees planted with peat wedges was higher than those planted without, particularly… Show more
