Overview

Angel trumpets, also known as Inca sun, are a fast-growing tree that produces yellow, trumpet-shaped blooms that hang downward. Their scent can be overpowering and intoxicating. These trees are commonly grown in containers due to their extreme weakness in cold temperatures. An angel trumpet grown in the ground must be pruned back to the soil or pulled up and re-potted indoors throughout the winter. Otherwise hardy, these trees make a beautiful addition to any flower garden.

Step 1

Mix a one-to-one ratio of rich compost and potting soil and add a handful of balanced fertilizer. Angel trumpets are an extremely heavy feeder and must be started off in rich, nutrient-filled soil.

Step 2

Fill half of a large pot with the mixture and water thoroughly to push out excess air in the soil. The container should be at least 2 feet deep and 1 foot wide. Plant at the same depth as the original container. Fill in the rest of the pot with the remaining mixture and water the plant.

Step 3

Place the pot in an area with full or partial sun. Initially, full sun is best for the plant, but as the summer grows hotter, the heat from full sun can cause the blooms to wither or cease blooming entirely.

Step 4

Fertilize the flower every two or three weeks with a general-purpose, balanced fertilizer. When spring arrives, switch your fertilizer to one that is high in phosphorus and fertilize twice a week to encourage more prolific blooms.

Step 5

Keep the soil moist, but never soaked, at all times. Water daily, but not so much that the plant is standing in water. The leaves will droop when the plant needs watering and will recover once it has gotten its fill. During extremely hot summers, water twice or even three times a day.

Step 6

Move the plant indoors during the winter, or any time the temperatures drop below 40 to 50 degrees F. Leave it in your basement and keep the soil relatively dry, but not arid. The plant will go into dormancy and the leaves will fall off. Once the last frost has passed, move the plant outside and resume its watering and fertilization schedule.

Tips and Warnings

  • Always use gloves when working with angel trumpets. All parts of the plant are extremely toxic.
