How to Grow and Care
This easily grown vine thrives in both sun and partial shade. While it prefers a nice well-draining soil, the Trumpet Vine flower is resilient enough to adapt to nearly any soil and will grow readily. Be sure to choose a suitable location before planting as well as a sturdy support structure.
Planting too close to the home or outbuilding could result in damage from the vine's creeping roots, so it's important that you plant the vine some distance from the house. They can work their way under shingles and even cause damage to foundations.
A trellis, fence, or large pole works well as a support structure when growing Trumpet Vines. However, do not allow the vine to climb trees as this can lead to strangulation.
When growing Trumpet Vines, containment is another consideration. Some people find it useful to plant Trumpet Vines in large bottomless containers, such as 5-gallon buckets, which can be sunk into the ground. This helps keep the vine's spreading habit under control. If the vine is located in a large enough area where its suckers can be routinely mown and pruned, it can be grown without the support and treat more like a shrub.
