- Watering: Adenium bonsai prefer well-draining soil. Water the plant thoroughly when the soil is dry to the touch, but be careful not to overwater as this can lead to root rot. During the growing season (spring and summer), water more frequently, but reduce watering during the dormant season (fall and winter).
- Light: Adenium bonsai thrive in bright, indirect sunlight. Place them in a location where they can receive plenty of sunlight throughout the day, but avoid direct afternoon sun, especially in hot climates, as it can scorch the leaves.
- Temperature: Adenium bonsai prefer warm temperatures above 50°F (10°C). They can tolerate some fluctuations in temperature but should be protected from extreme cold.
- Pruning: Regular pruning helps maintain the shape and size of the bonsai. Remove any dead or diseased branches, as well as any suckers that emerge from the base of the plant. Prune back long shoots to encourage branching and a more compact growth habit.
- Fertilizing: Feed adenium bonsai with a balanced fertilizer diluted to half strength every two weeks during the growing season. Reduce or stop fertilizing during the dormant season.
- Repotting: Adenium bonsai should be repotted every two to three years to refresh the soil and provide space for root growth. Repot in early spring before the growing season begins. Use a well-draining bonsai soil mix and prune the roots as needed.
- Pests and Diseases: Keep an eye out for common pests such as aphids, spider mites, and mealybugs. Treat infestations promptly with insecticidal soap or neem oil. Adequate air circulation and proper watering practices can help prevent fungal diseases such as root rot.
