Ivy is a genus of evergreen perennial vines containing dozens of species and cultivars. Ivy responds well to asexual or vegetative reproduction by division. Each healthy division of a mature root mass will result in an ivy plant identical to the parent from which it was taken. This feature allows ivy to be planted and established quickly over a wide area or shared with friends easily and at a low cost.
Slide the ivy plant from its growing pot or excavate the root mass from the planting soil. When harvesting divisions from large expanses of established ivy, simply dig out an area of plant foliage, soil and roots to provide the number and size of divisions you require.
Pull the divisions apart with gloved hands or use a sharp clean garden knife to slice off squares of chunks ivy. Make the divisions any size you like, but ensure that for every division there is healthy top foliage, soil and roots.
Transplant the divisions into nutrient-rich soil immediately, either into the ground or a container. Do not let the roots dry out between harvesting and planting. Keep the soil level on the plant stem consistent from the old planting site to the new.
Water the divisions and surrounding soil deeply until drenched several inches down. Maintain evenly moist soil at all times until the divisions are well established and spreading into their new soil.
