Trumpet vine care

Trumpet vine is a woody, multi-stemmed, deciduous vine that is easy to grow, but more difficult to maintain. If left unchecked, this plant will invade surrounding areas, including home foundations and structural elements. Provide the trumpet vine with a trellis structure to climb and attach through aerial roots. Native to southeastern North America, this vine grows well in most soil conditions, especially in forest or swampy environments. Areas that receive at least six hours of daily sunlight produce the most showy vines, which thrive on new growth.

Trumpet vine grows well in pollinator gardens, because it attracts hummingbirds. The self-seeding nature of this plant makes it invasive in most environments.

a light

Trumpet vines thrive best in areas that get several hours of direct sunlight. Plant them in full sun (at least six hours of sunlight per day) or partial sun (at least two hours of direct sunlight). It will grow foliage in shade but produces few flowers in shady conditions.

Soil

Trumpet vines grow in most average soil conditions, including loamy, loamy, and sandy soils. Keep the vines in moist but well-drained soil that resembles their native forest or swamp environments.

water

Trumpet vines are relatively drought tolerant. About one inch of water per week through rainfall or irrigation is sufficient, but this vine will need more water in the harsh summer heat if the foliage is wilting.

Temperature and humidity

Trumpet vine grows best in USDA zones 4-10. It prefers hot, humid climates but will grow in other areas. Less moisture will produce less vigorous chrome, making it easier to monitor.

Fertilizer

Fertilizers are not necessary to grow trumpet vines. These vines spread quickly without amending the soil with organic matter or adding nutrients. Excess nitrogen can interfere with blooming.

Types of trumpet vines

Trumpet vines are available in several varieties, including named varieties and upright types. Here are some trumpet vine species to know about:

  • 'Crimson Delight': Bright red-orange flowers appear in summer.
  • 'Flava': Buttery yellow trumpet vine blooms in summer and fall.
  • 'Flamenco': Vibrant orange-red flowers appear from mid-summer until frost.
  • 'Snazzy Brass': This golden-yellow cultivar blooms continuously, with abundant blooms from late spring into fall.

pruning

Prune trumpet vines throughout the year to help control the spread of the vigorously growing vine beyond the area you want it to climb. This vine thrives on new growth, so cut the vine back to the ground in early spring to make room for fresh flowers. Pruning can also be done in late fall to remove spent foliage or wilted flowers. Train trumpet vines to climb a trellis or vertical structure to help sustain growth and prevent seed pods from rooting in unwanted areas.

Deadhead blooms to avoid self-seeding and excessive spread. Seed pods will emerge from the flowers left on the vine, so remove the 6-inch pods unless you want to see more vines appearing in your garden.

To remove trumpet vine, an herbicide that targets the vines and brush should do the job, and it may take a few applications. Cut vines like these by the roots before spraying them with herbicide.

Vines trumpeted

Trumpet vines propagate easily and quickly through self-seeding, cuttings and root division. Here's how to propagate trumpet vines through cuttings:

  1. In summer, use sterilized pruning shears to pick cuttings from a healthy vine.
  2. Remove the leaves from the lower half of the plant and dip the cutting in rooting hormone if you prefer.
  3. Fill a pot with soil and plant the cutting directly into the mixture.
  4. Keep the soil and container moist in a shaded environment for at least a month or until the cuttings root.
  5. Dig up the sprouts in late winter or early spring and transplant them into a container or larger garden.

How to grow trumpet vines from seed

Trumpet trees are self-seeding, but to reproduce these plants in a new location using seeds, here's what you need to know:

  1. Harvest trumpet vine seeds before they open and after they turn brown, usually two to three months after flowering.
  2. Split the seed pods and collect the seeds. Allow the seeds to air dry on a paper towel before storing them in a sealed container and placing them in the refrigerator.
  3. Trumpet vine seeds need to be stratified for 30 to 60 days at a temperature of 41°F to 50°F.
  4. Plant the seeds in a container or in the garden in the spring, planting the seeds in moist, well-drained soil.

winter

Annual pruning helps protect trumpet vines over the winter. Cut the vines to the ground in early spring—also works in late fall or early winter. This pruning involves removing stems, foliage and side shoots. Remove dead, damaged or diseased branches to maintain the health of the vine.

Common plant pests and diseases

Trumpet vines are resistant to most pests and diseases. However, powdery mildew and leaf spot may occur when vines are grown in areas without proper air circulation.

How to make trumpet vines bloom

Trumpet vines grown in full sun and well-drained soil should thrive without many problems. Fertilization is unlikely to be beneficial because excess nitrogen interferes with flowering. Newly planted plants may take up to five years to begin blooming. Newly planted trumpet vines can take three years to produce flowers.

Common problems with trumpet vines

Trumpet vines are easy to grow. Some concerns about growing this plant are due to its aggressive growth rate and invasiveness in most environments. Here are some things to know when planting and caring for this vine:

Leaves turn black/brown

Interrupted water flow causes trumpet vine leaves to wilt and turn brown. Wilting or burning of leaves also results from insufficient air circulation around the vine, soil that is too dense, root damage, or bacterial or fungal infection. Depending on the label, treat the fungus with an herbicide designed for vines according to the instructions.

Vines reproduce in the house or trees

Trumpet vines have a highly flammable rating. Because of this risk, avoid planting trumpet vines near building structures or in areas where wildfires are common and keep the vines well pruned. Aerial roots can also damage paint or siding.

Trumpet vine will climb trees if allowed to do so, so it is best to plant it away from any trees and prune it regularly to keep it under control.

Frequently asked questions

  • What happens to trumpet vine in winter?

    As a fast-growing perennial, trumpet vine loses its leaves in the winter. In late spring, green shoots will appear, but in winter, they will have a messy appearance and dead branches.

  • How many times a year does trumpet vine bloom?

    Trumpet vines thrive on new growth, so cutting back deadheads after they flower will encourage them to re-emerge. The trumpet-shaped yellow, orange and red flowers bloom from June to September in summer.

  • What is a less invasive alternative to trumpet vine?

    Coral honeysuckle (Lonicera sempervirens) is a twining native vine with red, trumpet-shaped flowers that attract hummingbirds. The vines are less aggressive and evergreen throughout most of the South.
