I want to grow a trumpet vine into a bush like plant
I have heard that a trumpet vine can be made to look like a bush and I would like to do this in my yard, but I am not sure how to go about doing it. Do I just keep on cutting it back or what?
Yes. Vigorous and persistent use of pruning shears will keep the trumpet vine to a bush-like appearance. This article has a lot of other growing information: https://www.gardeningknowhow.com/ornamental/vines/trumpet-vine/growing-trumpet-vines.htm
