Growth Conditions for Synnotia bicolor (Thunb.) Sweet var. roxburghii Baker
Light: Synnotia bicolor thrives in bright, indirect light. Direct sunlight can scorch the leaves, so it is advisable to keep the plant in a shaded area during the hottest part of the day.
Temperature: This plant is native to the tropical regions of Asia, and it prefers warm temperatures. Ideally, the temperature range should be between 18°C to 28°C. Protect the plant from drafts and cold temperatures.
Soil: Synnotia bicolor prefers well-draining soil that is rich in organic matter. The pH level of the soil should be between 5.5 to 6.5. It is advisable to use a potting mix that contains perlite or vermiculite to improve drainage.
Water: The plant likes to have consistently moist soil, but it is important not to overwater it. Water the plant only when the top inch of soil is dry to the touch. Avoid getting water on the leaves, as this can cause fungal growth and damage the plant.
Fertilizer: Fertilize the plant once a month during the growing season (spring and summer). Use a balanced, water-soluble fertilizer that is diluted to half-strength. Do not fertilize during the winter months, as this can be harmful to the plant.
Humidity: Synnotia bicolor prefers high humidity levels. You can increase humidity by misting the leaves daily or by placing the plant on a pebble tray filled with water.
Propagation: The plant can be propagated by cuttings. Take a stem cutting that is 4 to 6 inches long, and remove the lower leaves. Dip the cut end in rooting hormone, and plant it in a potting mix that is moist but well-draining. Keep the cutting in a warm, bright location and mist the leaves daily. Roots should form within 4 to 6 weeks.
Pests and Diseases: Synnotia bicolor is prone to mealybugs, spider mites, and fungal diseases. Watch for signs of infestation, such as yellowing leaves, and treat with an appropriate pesticide or fungicide.
Cultivation
The plant Synnotia bicolor (Thunb.) Sweet var. roxburghii Baker thrives in well-draining soils that are rich in organic matter. It prefers full sun exposure, but it can tolerate partial shade as well. The plant can be propagated via stem cuttings or seedlings.
Watering Needs
Regular watering is required for the plant to thrive. However, one ought to avoid over-watering as it may lead to root rot and other diseases. The soil should be moist but not waterlogged. During the hot and dry seasons, watering should be done frequently, and mulching should be utilized to retain soil moisture.
Fertilization
Fertilization should be done at the beginning of each growing season. Nitrogen-rich fertilizers should be used to promote healthy vegetative growth. Surface application of well-rotted manure can provide the plant with nutrients as well. Plants in containers should receive liquid fertilizers every two weeks during the growing season.
Pruning
Pruning is done to control the plant's growth and to remove dead or diseased parts. Young plants should be pruned to promote bushy growth. Pinching off the tips of the stem encourages branching and results in more flowers. Deadheading also promotes additional blooming. Pruning should be done during the dry season to avoid infection by fungi. Winter pruning should be minimal, and diseased plant parts should be removed only.
