Temperatures below 15°C (59°F) or above 30°C (86°F) can affect the growth and survival of the plant. In colder regions, it is best to grow the plant indoors or in a greenhouse with controlled temperature and humidity levels.
Soil Requirements:
The Clerodendrum ulugurense Gürke thrives in well-draining, rich, and fertile soil. The soil pH should be slightly acidic to neutral, between 5.5-7.5, and should have good water retention capacity. The plant prefers moist soil but can tolerate periods of drought. Adding organic matter, such as compost or aged manure, to the soil can improve soil fertility and structure, promoting healthy plant growth.
Cultivation methods for Clerodendrum ulugurense Gürke
Before planting Clerodendrum ulugurense Gürke, consider that it grows in warm temperate to tropical climates. Therefore, it is best cultivated in warm, fertile, well-drained soils with a pH range of 6.5 to 7.5. The plant grows best in areas receiving bright light, but partially shaded areas are also adequate.
Watering needs for Clerodendrum ulugurense Gürke
Clerodendrum ulugurense Gürke requires frequent watering. During the growing season, it is essential to ensure that the soil is moist but not saturated. Keep the roots well-drained and water them when the soil dries to a depth of 1-3 inches. In the dormant season, watering should be reduced.
Fertilization for Clerodendrum ulugurense Gürke
Clerodendrum ulugurense Gürke benefits from annual fertilizer application. You can supply it with well-balanced, slow-release fertilizer granules or liquid feed. During the growing season, fertilize the plant every two weeks; in the dormant season, cut back to once every month.
Pruning for Clerodendrum ulugurense Gürke

Propagation of Clerodendrum Ulugurense Gürke
Clerodendrum ulugurense Gürke is a rare and exotic plant that is native to Tanzania. The plant is easy to propagate and can be propagated by different methods, including:
Propagation by Seeds
Seeds are the most common method of propagation for Clerodendrum ulugurense Gürke. The seeds are collected from the mature fruit of the plant and allowed to dry for a few days. After drying, they are sown in a nursery bed and covered lightly with soil. The seeds should be kept in a warm and humid environment, and they will germinate within two to three weeks.
Propagation by Cuttings
Cuttings are another method of propagating Clerodendrum ulugurense Gürke. This method is best for those who want plants that are identical to the parent plant. Select a healthy stem from the parent plant and make a clean cut below the node. The cutting should be about 6 inches long and have a few leaves. Dip the cutting in rooting hormone and plant it in well-draining soil. Keep the soil moist and place the cutting in a warm and bright location. The cutting will start rooting within a few weeks.
Propagation by Division
Propagation by division is best for mature plants. Divide the parent plant into two or more sections during the plant's dormant season. Each section should have healthy roots and shoots. Plant the sections in well-draining soil and keep the soil moist. The new plants will start growing once they are established.
