However, despite needing minimal care, trumpet vines are still a high-maintenance plant to have in your garden. The maintenance that will require the most time and effort on your part is to prune back your trumpet vines aggressively to keep them under control. Also, pull up any new shoots that pop up from the soil as you spot them, and be sure to regularly monitor for them. Also, remove the seed pods before they open and let their seeds spill out into the soil for germination.


Pruning

It is almost impossible to prune this plant too much due to its vigor. Trumpet vines bloom on new stems, so prune early in the spring before growth starts. Cut the plant back to nearly ground level, leaving only a few buds. This kind of aggressive annual pruning is the best way to keep the plant in check.
