Jasmine grows on lattice and other structures using a method called twining. Twining vines grow and wrap themselves through a structure. As the lower part of the vine grows, it thickens and becomes woody. Jasmine gradually climbs a lattice trellis by continually, naturally weaving new growth in and out of the openings in the trellis. Not all vines are twining vines. Some vines use tendrils that grab onto the structure while the plant grows, while others use sticky, aerial roots to hold themselves to their support structure.
Plant jasmine about eight to 12 inches from the base of a lattice trellis. This vine can grow up to 30 feet tall, making it ideal for a tall trellis or for an arbor. Though a vigorous grower, jasmine remains small with frequent pruning, making it a versatile climber for the landscape. Encourage the newly developing plant by gently weaving the vines into the lattice as they grow tall enough to reach the bottom. Once the plant takes hold and starts twining, it can find the structure on its own.
Jasmine is not winter hardy below USDA zone 7, but that does not need to stop the cold-climate gardener from enjoying this fragrant climber. Plant jasmine in a container and drive a lattice trellis into the soil at the back of the container. When winter frosts threaten, drag the whole pot and the trellis indoors for the winter. Planting pots, with trellises already in place, are available at home and garden centers, making for convenient ready-made planters.
Planted in a pot or in the ground, jasmine requires pruning to keep it a manageable size. Prune jasmine in late summer or early fall after the flowers fade. As you prune, encourage the tender tips across the trellis by gently weaving them into the lattice. Prune out dead wood and remove growth that invades pathways or other space. Prune back container-planted jasmine hard in the fall to keep it small enough for the planter and trellis.
