How to Care for the Plant

Water
Never allow the soil to completely dry. Water the Cestrum when the top one or two inches of soil has dried. When watering, soak Cestrum thoroughly and allow the water to drain around the base.
Fertilizer
For healthier growth, feed the plants once or twice per month. Dilute the liquid fertilizer before use.
Sunlight
When grown outdoors, the Cestrum tolerate light shade or full sun. Brighter light helps encourage longer lasting blooms. If grown behind glass, the plants require bright, indirect sunlight. Place them in south-facing or west-facing windows for the most exposure to the sun.

Soil
Use large tubs, clay pots, or baskets filled with rich soil with good drainage. In warm regions, the plants can grow in the ground, if they’re not considered invasive in your area.
Temperature
Most species of Cestrum are winter hardy in USDA hardiness zones 8 to 11 and can tolerate temperatures down to 50° degrees Fahrenheit during the colder months. In the summer, Cestrum grows best in temperatures in the upper 70° degrees Fahrenheit.
Container
Potted plants require repotting every two to three years. Repot into larger containers if needed.
