Q: I have been cutting down my angel trumpet plant each fall but do I have to do this?. They come back in the spring but it takes all summer for them to bloom.
A: You can cut them down or leave them in place. Either way, winter cold will freeze the stems down to the ground and you’ll remove them in spring when new growth starts. In my experience, some varieties of angel trumpet are naturally late to bloom, while others start flowering in mid-summer.
