How to Callus Vine Cuttings

Locate an area of the yard with sandy soil and a shady to partially shade location. Do not choose a location with full sun, as this dries the soil too much before calluses form and kill the vine cuttings.

Dig a trench deep enough to accommodate the length of the cutting plus an additional 8 inches. A 2-foot deep trench accommodates most cuttings.

Place the cuttings into the trench with the cut end facing upward. Fill in the trench so that the cutting stands upright and is covered with 6 to 8 inches of soil. If you are planting multiple cuttings, bundle them together in clumps tied very loosely with gardening tape.

Water the soil to dampen it. Later, water the soil during drought to keep the soil damp at a 6- to 8-inch depth.

Check the cuttings once per month by digging down to the cut surface of one vine. When you see a white layer forming on the cut end, the callus has properly formed and you can dig up and transplant the cuttings.
