Velda’s Plant Sock is very fine-meshed and strong, preventing the roots of pond plants from proliferating and pond soil from leaching out. Plant Sock is suitable for all types of pond plants. For planting and concealing pond edges and bends. Fill the sock with pond soil and place several pond plants in the sleeve. Wet the soil well and close the sock with the snaps. For exuberant growth, add growth bulbs.
