  • water dropWater

    Angel's trumpet should be watered thoroughly, ensuring that the soil remains moist but not soggy. Generally, in the growing season, watering once every 2 to 3 days with around 1 to 2 gallons per watering event, depending on the size of the plant and the weather conditions, is appropriate. The soil should be allowed to dry out slightly between waterings to prevent root rot. During the hotter parts of the year, watering frequency should be increased, while in cooler temperatures, it should be decreased. Always check the top inch of soil for dryness before watering to adjust your schedule accordingly.

  • sunLight

    Angel's trumpet thrives best in a location that receives full sun to partial shade. The ideal spot would provide at least 6 hours of direct sunlight daily, with some dappled shade in the afternoon to protect it from the intense heat. Avoid placing the plant in deep shade, as this can inhibit flowering and lead to leggy growth.

  • thermometerTemperature

    Angel's trumpet prefers warm temperatures, ideally between 60°F and 85°F. It can tolerate a minimum temperature of around 50°F but should be protected from frost, which can cause significant damage. At temperatures above 85°F, the plant may require additional shading and watering to prevent heat stress.

  • scissorsPruning

    Angel's trumpet benefits from regular pruning to stimulate growth, enhance flower production, and maintain an attractive shape. Prune back in late winter or early spring before the onset of new growth, removing any dead or crossing branches. A heavy prune, cutting back up to one-third of the plant, can be done every few years to rejuvenate older plants. Light pruning and removal of spent flowers can be performed throughout the growing season to encourage further blooming.

  • circleLife cycle

    Brugmansia × candida 'Knightii,' commonly known as Angel's Trumpet, begins its life cycle as a seed, which, once sown, will germinate and develop into a seedling under appropriate conditions of warmth and moisture. The seedling then grows into a young plant with characteristic large, soft leaves and begins to establish a root system. As it matures, the plant becomes a bushy shrub and starts to produce its distinctive large, pendulous, white flowers that are fragrant at night, normally during late spring to fall, depending on the climate. After pollination, typically by moths or other nocturnal insects, the flowers will develop into seed pods containing numerous seeds. Angel's Trumpet is a perennial, and in suitable climates, it will experience a period of dormancy during the winter months before resuming growth in the spring. Gardeners often propagate the plant through cuttings, which allow new plants to bypass the seed stage and grow directly into young plants, completing the life cycle.

      Spring to Summer

    • Brugmansia × candida 'Knightii', commonly known as Angel's Trumpet, is often propagated through stem cuttings. The most popular method is to take semi-ripe cuttings during late spring or early summer when the plant's growth is most active. A cutting should be about 6 to 8 inches (15 to 20 cm) long and include at least two nodes. The leaves near the bottom of the cutting should be removed, and the cut end may be dipped in rooting hormone powder to enhance root development. The cutting is then planted in a well-draining soil mix and kept moist but not waterlogged. It's important to keep the cuttings in a warm area with indirect light until roots develop, which typically takes a few weeks. After sufficient roots have formed, the new Brugmansia plants can be transplanted into individual pots or directly in the garden, depending on the climate.
