Trumpet Flower Vine is easy to grow. They prefer full sun, but will tolerate
partial shade. Plants like a rich soil to fuel their fast growth. Mix a healthy
dose of compost into the soil prior to planting.
Plants like a lot of water and nutrients. Keep soil moist. Add general purpose
fertilizer when planting, and every two to three weeks during the season.
Switch to a high phosphorous formula just before the blooming period.
Trumpet Flower Vine needs some form of support to climb up. Trellises or
fences work well.
Keep the areas weeded when plants are young. A layer of mulch will keep weeds
down, and create a neat appearance.
Trumpet Flower Vine can be invasive. They are good "re-seeders". If the pods
are allowed to open and pour out their seeds, you will find many new plants
next year. Do not disturb the soil until seedlings have begun to grow.
Thinning will almost certainly be needed. If you don't want them to spread
too rapidly, pick seed pods as they appear.
