Light Plant angel's trumpet in a spot that boasts full sun. However, in especially hot or dry environments, it can stand to have a bit of shade, especially during the warmer afternoon hours. Angel's trumpet needs six to eight hours of sunlight daily to thrive and produce the best blooms. Soil Prepare moist but well-draining soil for angel's trumpet that's ideally high in organic matter. This perennial does not like to sit in soggy soil. This plant will typically do well in a potting mix designed for azaleas and camellias if grown in pots. Water Water angel's trumpet well and often. It needs more water when the weather is warm. Container specimens may need to be watered twice a day during the peak of summer. Never let the soil dry out; give your plant at least 3 inches of water a week. Temperature and Humidity Keep angel's trumpet warm. Outside its perennial zones (9 through 11), it shouldn't be outside when the temperatures drop below 50°F. In cooler zones, plant your angel's trumpet in a container that you can move to a dark, frost-free place, such as a garage. You can allow it to go dormant. Fertilizer Fertilize angel's trumpet regularly. Use a water-soluble fertilizer, and avoid slow-release formulas, as these do not work fast enough for the plant. Bloom-boosting fertilizers, such as 15-30-15 or 10-50-10 mixtures, are best. For the amount to use, follow product label instructions.
