Maintaining and Propagating Vines

This garden is multi-leveled, with lots of interesting nooks and crannies in which to add character.

As the creeping fig vine matures, its leaves become more oval shaped and darker green.

When a vine begins to overrun a space, it's time to get out the shears.
This hilltop home in Zone 9 was built on several levels to take advantage of the spectacular view below. The many levels create challenges with necessary retaining walls, fences and stone structures in the landscape. Many vines already soften the hard edges, but they are in need of maintenance. Master gardener Chris Dawson demonstrates how to cut back and propagate vines to keep them growing where they are wanted.

An adult creeping fig (Ficus pumila) frames a double garage but has started to grow into the rain gutter and down onto the garage doors. There is also a bougainvillea (Bougainvillea x buttiana) that has grown down low enough to become a hazard to cars and pedestrians. Dawson gives some tips for pruning vines:

  • Be careful not to sever any main leads that tie to other parts of the vine; you don't want to create patches of dead vine.
  • Use sharp shears for nice clean cuts to reduce the chance of disease.
  • Most vines are vigorous and can withstand a heavy pruning. Remove as much of the plant as you need to, especially if it is a hazard.
  • Bougainvillea should be pruned after the danger of frost has passed.

Ivy that is held against the soil will eventually take root and form a new vine.
Along one of the garden walls is an English ivy. Dawson uses a propagation technique called "layering" to train it in the desired direction. Using a section of coat hanger wire, Dawson pins the section of ivy to the ground so that the vine makes contact with the soil. Once the new vine is established, the old vine can be cut away.

Honeysuckle (Lonicera) doesn't need a vertical structure to support its growth. It twines around itself and creates a cascading mound that covers the ground. Most varieties of this vigorous vine are hardy in Zones 4-9. Honeysuckle is easy to propagate.

  • Cut four-inch sections from the vine.
  • Strip the leaves off the section of vine that will be planted in the ground.
  • Space the vines 18 inches apart.

Dawson plants the honeysuckle cuttings around a wooden fence that contains a compost pile. As the cuttings grow, they will cover the area and the compost bin will disappear behind a cover of green leaves.
