Angel trumpet plants are members of the nightshade family, making them as deadly as they are gorgeous. If your garden is not home to small children or plant-chewing pets, these plants are a lush addition to any landscape. Angel trumpets can grow as tall as 20 feet. You can prune angel trumpets at any time of the year and as often as you like.
Check new plants for at least one "Y" branching. If they do not have a Y branch, they are not ready to be pruned. Leave them alone until they have branched.
Examine your Angel Trumpet to determine the difference between new growth and old. New growth will be a fresh, green color, while older growth will be more gray and appear more dry.
Replace the potting soil in potted angel trumpet plants at least once a year to keep the flow of nutrients fresh.
Never handle an angel trumpet plant without gloves.
