Growing The Trumpet Vine 

During the summer, clumps of trumpet-shaped orange, red, or yellow blooms develop, reaching 1 to 3 inches in length before yielding to bean-like seed capsules. These blooms attract hummingbirds and many other pollinators. In the fall, the leaves turn yellow before falling off the plant for the winter. When fully grown, the Trumpet vine may reach a height of 40 feet and is a vigorous grower. As such, extreme care is vital. New branches can sprout feet away from the parent plant, swiftly exiting the garden and establishing thickets that suffocate neighboring plants.

Sunlight

Trumpet vines may thrive in a variety of conditions, from full sun to moderate shade. The finest flowering occurs in full sun, which means at least six hours of direct sunshine on most days. If your environment is really hot, you may want to offer it some afternoon shade to keep it healthy.

Soil

Fertilizing

There is no essential need for extra fertilizers since Trumpet vines are active spreaders and may survive in poor soil. Trumpet vines that don’t bloom can be caused by too much fertilizer or too rich soil. Planting Trumpet vines on lean or rocky soil produces the finest results. Fertilization, particularly heavy nitrogen fertilizer, may produce a lot of huge, lush leaves, but it focuses the energy on the foliage while neglecting the blossoms. Phosphate-rich fertilizer, such as bone meal, may enhance Trumpet vine flowering.

Invasiveness

The Trumpet vine is classified as an invasive weed by the United States Department of Agriculture. However, if handled properly, they can be wonderful. However, because severe frequent pruning is required to limit growth and spread, the Trumpet vine is still a high-maintenance plant. Keeping Trumpet vine under check requires eliminating undesirable shoots from your grass and removing seed capsules to prevent self-seeding. Each seed is linked to white fluff that lets the seeds be blown by the wind, similar to milkweed seeds. When handling seed pods and seeds, gloves are recommended since skin contact can cause hives and other rashes.

Growing The Trumpet Vine  In Containers

Trumpet vines in pots will not gracefully flow around the pot’s edge. They can reach a length of 25 to 40 feet and a width of 5 to 10 feet. Choose a pot that can carry at least 15 gallons, such as half barrels. Trumpet vines are hardy in USDA zones 4 through 9, so you may be able to leave yours outside all year. This is ideal since the vines climb by twining and suckering, and it may be tough to move them indoors once they’ve established themselves. As a result, make sure your Trumpet vine plants in containers have something solid and broad to climb, such as a wooden or metal trellis.

Care & Tips

The Trumpet vine may swiftly coat fences, stone walls, arbors, fence posts, and other structures, offering a lovely green focus piece for landscapers willing to put in the work to limit its spread. It can also be used to conceal rock piles, stumps, waste heaps, and other objects on the ground. Because this vine may easily overtake trees or structures, it requires a strong support system. Plant it away from foundations, since the spreading vines can cause harm. Similarly, plants may infiltrate shingles and cause harm.

Common Problems

There are no severe insect or disease concerns with Trumpet vine. The Trumpet vine’s most common complaint is that it grows out of control, causing damage to foundations and buildings, as well as strangling out adjacent trees, bushes, and other plants. As a result, Trumpet vine should be kept at least 6 to 12 feet away from any structures or trees. Trumpet vine is a flammable plant that should not be planted near basements or building walls in areas where wildfires are a possible risk. A mismanaged plant that isn’t clipped back once a year might wrap a home or garage, posing a major fire hazard.

Propagating Trumpet Vines

Cuttings are the most common way to propagate Trumpet vines, and container-grown Trumpet vines are no exception. The plant can also be cultivated from seed, however, seedlings normally take many years to produce any significant amount of blooms. It does, however, root readily from cuttings, and is one of the causes of the species’ invasiveness. Water thoroughly but carefully after planting your cutting in well-draining soil. Pour water with a nozzle spray attachment until it streams freely out the drainage holes to moisten the whole container’s worth of soil without stagnating or degrading. When the topsoil becomes dry, water it. In pots, Trumpet vines require time to establish strong root systems.

The History Of The Trumpet Vine

Trumpet vine is a flowering plant genus in the Bignoniaceae family that is endemic to China and North America’s woodlands. It has two species, and both are robust deciduous perennial climbers that cling to the ground with aerial roots and bloom in the summer with beautiful trumpet-shaped flowers.
