How to Grow Trumpet Vine & Care Guide

Known as the trumpet creeper or trumpet vine, Campsis radicans is a fast-growing perennial vine that thrives in full sun.

Despite the fact that some gardeners consider trumpet vines invasive, they may be maintained under control with proper care and trimming.

Trumpet Vine Plant

With its trumpet vine flower, the landscape can be invigorated by hummingbirds.

A rainbow of hues is represented by the blooms’ tubular form, which might be yellow, orange, or red.

This vine blooms all summer and into fall. However, those planted in shade may only get one or two blooms.

The seedpods of trumpet vines, which appear after flowering, are lovely bean-like structures.

The USDA plant hardiness zones for the Trumpet Vine are 4 through 9. The woody vines are usually strong enough to survive the winter, whereas other growth normally dies back and re-emerges in spring.

Pruning these vines, which can grow 30 to 40 feet (9 to 12 meters) in a single season, is often necessary.

Trumpet creeper is exceedingly difficult to remove if it is allowed to take hold.

How to Grow Trumpet Vine

In both full sun and partial shade, this vine thrives.

Well-drained soil is preferred, but the trumpet vine flower is adaptable enough to grow in practically any soil.

Choosing an appropriate place and a solid support structure before planting is essential.

If you plant the vine too close to your home or outbuilding, the vine’s creeping roots could cause damage, so be sure to set the vine back from the structure.

They are able to get under roofs and even harm the foundations when they do so.

Trellis, fence,s or huge poles can be used to support trumpet vines when they are growing.

Keep the vine from climbing trees, since this could result in strangulation.

Another factor to keep in mind when cultivating trumpet vines is their containment.

The use of large, bottomless containers like buckets (3.75 gallons) to bury trumpet creepers has been found to be beneficial by some gardeners. This helps restrict the vine’s tendency to spread.

It is possible to treat the vine more like a shrub if it is situated in an area large enough to allow for regular mowing and pruning of its suckers.

Care of Trumpet Vines

Once grown, the Trumpet vine takes very little maintenance. Trumpet creeper is a fast-growing plant. Don’t fertilize or over-water; only water as needed.

Pruning is the only real requirement in terms of upkeep. Pruning the trumpet vine on a regular basis is necessary to keep it in check.

Spring and October are the best times for pruning. It’s best to prune the plant in the spring, and only a few buds should remain.

Another helpful idea is to deadhead trumpet vine flower pods as soon as they develop.

Plants that reseed will be less likely to spread to other sections of the landscape.

Pruning

It’s nearly impossible to over-prune this hardy specimen. During the spring before growth begins, prune trumpet vines.

Remove everything but a few buds from the plant and cut it back to the ground.

After the leaves have dried and fallen in the late autumn, you can also prune back the shrubs.

The easiest approach to keep the plant in check is to prune it aggressively every year.

Although you may lose some blooms, you can also prune vines throughout the season.

Using wire strung across the surface of a structure, such as a garage or outbuilding, may help the vine grow.

Using a tree stump as a base for the trumpet vine allows you to easily prune it during the growing season.

Propagating Trumpet Vine

Reproduction of trumpet vine is possible in a variety of ways, but the simplest is to dig up one of the suckering runners and transplant it to the appropriate site.

When new growth is just beginning to emerge, this is a good time to perform this task.

How to Grow Trumpet Vine From Seed

You can simply dig up a seedling that has self-seeded and plant it in a new location, as this plant easily reproduces.

The crown of the seedling should be at the soil level when it is planted.

After the petals have faded, you can gather the bean-like capsules that contain the seeds and direct-sow them where you like.

Potting and Repotting Trumpet Vine

Trumpet vine grows well in containers because of its rapid proliferation and the ease with which it may be contained.

A large, hefty container is required, such as a half-barrel or a 20-plus gallon concrete or ceramic planter, though.

When you’re ready to plant the vine, add some all-purpose potting mix to the container and a sturdy climbing trellis.

In order to prevent the trumpet vine from spreading its roots and perhaps harming other plants, dig a hole large enough to suit a bottomless bucket container.

Plants should have their roots gently loosened and placed in the soil, preferably with a trellis to provide support.

Every year, in the late fall or early spring, you’ll need to cut the vine back to just above soil level.

Because of their tiny size, ‘Apricot’ and ‘Indian Summer’ make excellent container plants.

Overwintering

This plant does not need any winter protection if it is planted in its designated hardiness zone.

Pruning it severely in late fall or early winter—but not later than early spring—will help to keep it from taking over a space.

How to Get Trumpet Vine to Bloom

This plant will bloom profusely all summer long if it is placed in direct sunlight.

Pruning too late in the spring, which removes the young growth on which the flower buds are based, is the only obstacle to beautiful blooming.

Flowers may be sacrificed in favor of too vigorous green growth if too much food is given.

In general, these plants perform better with neglect than careful attention and don’t require any feeding at all to blossom.

Common Problems With Trumpet Vine

Not cultural issues, but excessive growth are the most frequently voiced criticisms of trumpet vine.

Uncontrollable Spread

As a general rule, the most prevalent complaint about the trumpet vine is its tendency to encroach on other plants and structures, harming foundations and walls.

As a result, the trumpet vine should be planted at least six to twelve feet away from any structures or trees.

A homeowner may appreciate this plant for a few years before becoming fed up with it and attempting to get rid of it.

Fire Hazard

If you live in an area where wildfires are a common concern, you should avoid planting trumpet vine near foundations or building walls.

A fire hazard can be created if a neglected plant grows around a home or garage without being cut back each year.
