If you are looking for a fast-growing vine to cover your fence or trellis, silver lace vine (Polygonum aubertii syn. Fallopia aubertii) might be the answer for you. This deciduous vine, with its fragrant, white flowers, is very easy to propagate.

Silver lace vine propagation is often accomplished by cuttings or layering, but it is also possible to start growing this vine from seed. Read on for more information on how to propagate a silver lace vine.

Propagating Silver Lace Vines

Silver lace vines cover your pergolas in no time at all and can grow as much as 25 feet (7.5 m.) in one season. The twining vines are covered with tiny white blossoms from summer through autumn. Whether you prefer planting seeds or rooting cuttings, silver lace vine propagation is not difficult.

Silver Lace Vine Cuttings

You can accomplish the propagation of this plant in several different ways. Propagating is most often done by taking silver lace vine cuttings.

Take 6-inch (15 cm.) stem cuttings in the morning from the current year’s growth or the growth of the prior year. Be sure to take the cuttings from vigorous, healthy plants. Dip the cut stem in a rooting hormone and then “plant” it in a small container filled with potting soil.

Keep the soil moist and retain humidity by keeping the pot wrapped in a plastic bag. Site the container in indirect sunlight until the cutting has rooted. Transplant to the garden in spring.

Growing Silver Lace Vine from Seed

You can also start growing silver lace vine from seeds. This way of propagating takes longer than rooting cuttings but is also effective.

You can acquire seeds online, through a local nursery, or collect them from your own established plants once the blooms have faded and the seeds pods have dried.

Scarify the seeds prior to sowing. Then either germinate them in a damp paper towel for transplant later or sow the seeds after all chance of frost has passed.

Other Silver Lace Vine Propagation Techniques

You can also divide the silver lace vine in early spring. Simply dig up the root ball and divide it in the same way you would other perennials, like Shasta daisies. Plant each division in a different location.

Another popular way to propagate silver lace vine is called layering. You may wonder just how to propagate a silver lace vine by layering. First, select a flexible stem and bend it across the ground. Make a cut in the stem, put rooting compound on the wound, then dig a hole in the ground and bury the wounded section of the stem.

Cover the stem with peat moss and anchor it with a rock. Add a layer of mulch over it. Keep the mulch moist for three months to give it time to root, then cut the stem free from the vine. You can transplant the rooted section to another location in the garden.
