Temperature
This plant prefers warm temperatures and does well in tropical climates. It thrives best at temperatures between 18°C to 30°C (64°F to 86°F). Care should be taken to avoid exposing the plant to temperatures below 15°C (59°F) as this could negatively impact its growth.
Soil Requirements
The soil texture plays an important role in the growth and development of this plant. A well-draining soil mix that is rich in organic matter is optimal. Premna chrysoclada (Bojer) Gürke prefers a slightly acidic to neutral soil with pH ranging from 5.5 to 7.0. It is also important to ensure that the soil is consistently moist but not waterlogged, as this could cause root rot.
Cultivation of Premna chrysoclada (Bojer) Gürke
Premna chrysoclada (Bojer) Gürke, commonly known as the Golden-leaved Premna, is a tropical shrub found in Madagascar. This plant grows well in warm and humid environments, and it can reach a height of up to 2m. Here are some cultivation methods that will help you grow and take care of your Golden-leaved Premna.
Watering needs
Golden-leaved Premna needs moderate watering, which means you should water it when the soil is dry to the touch. Avoid wetting the plant's leaves as it can lead to fungal infections. Depending on the temperature and humidity, you can water the plant once or twice a week.
Fertilization

The cuttings should be kept moist and warm until new growth starts to appear. Once the new growth appears, the cuttings can be transplanted into larger pots and grown until they are big enough to be planted outdoors.
Air layering propagation
Air layering is another effective propagation method for Premna chrysoclada (Bojer) Gürke. To do this, select a healthy branch and make a small cut into the bark. Apply rooting hormone to the cut and wrap the area with moist sphagnum moss or a similar medium. Cover the moss with a plastic wrap to keep it moist and secure it with a string. Roots should develop in a few months, after which the branch can be transplanted into a pot or directly into the ground.
Overall, Premna chrysoclada (Bojer) Gürke is a versatile plant that can be propagated through several methods, including seed propagation, stem cutting propagation, and air layering propagation.
Disease and Pest Management for Premna chrysoclada (Bojer) Gürke
Premna chrysoclada (Bojer) Gürke, also known as the Golden-leaved Premna, is a popular plant species among garden enthusiasts due to its striking golden leaves. However, like any other plant species, it is susceptible to diseases and pest attacks that can compromise its health and appearance. In this section, we will discuss some common diseases and pests that may affect this plant and suggest ways to manage them.
Common Diseases
Powdery Mildew: This fungal disease is characterized by a white powdery substance on the plant's leaves, stems, and flowers. It thrives in warm and humid environments, making it a common disease in greenhouses. To manage powdery mildew, remove the infected parts of the plant and improve air circulation by spacing the plants out or providing adequate ventilation. You can also treat the plant with a fungicide spray to prevent further spread.
Root Rot: Root rot is a fungal disease that affects the roots of the plant, causing them to become mushy and discolored. This disease is caused by excessive moisture and poor drainage. To manage root rot, remove any infected parts of the plant and improve soil drainage by repotting the plant with fresh soil and ensuring the pot has proper drainage holes.
Common Pests
Spider Mites: Spider mites are tiny pests that spin webs on the plant's leaves and suck sap from the leaves, causing them to turn yellow and eventually fall off. To manage spider mites, spray the plant with a mixture of water and insecticidal soap or neem oil. You can also release predatory mites that feed on spider mites to control their population.
Mealybugs: Mealybugs are small white, cotton-like pests that feed on plant sap, causing the leaves to turn yellow and stunt the plant's growth. To manage mealybugs, you can remove them with a cotton swab dipped in rubbing alcohol or spray the plant with insecticidal soap. You can also introduce natural predators such as lacewings or ladybugs that feed on mealybugs.
Aphids: Aphids are small pear-shaped insects that feed on plant sap, causing the leaves to curl and turn yellow. To manage aphids, spray the plant with a mixture of water and insecticidal soap or neem oil. You can also introduce natural predators such as ladybugs, lacewings, or parasitic wasps that feed on aphids.
By following these disease and pest management techniques, you can help ensure that your Premna chrysoclada (Bojer) Gürke plant stays healthy and beautiful for years to come.
