DETAILS

Care Instructions
Trachelium caeruleum requires bright, indirect light and moderate temperatures. It prefers a humid environment but can tolerate average household humidity levels. Water the plant when the top layer of soil dries out, ensuring it does not become waterlogged. Regular pruning helps maintain its shape and encourages new growth.
Soil
This plant prefers well-draining loamy soil. A mix of garden soil with some sand and organic matter works well. Ensure the soil is kept moderately moist but not waterlogged to prevent root rot.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season to promote healthy growth and flowering.
Repotting
Repot Trachelium caeruleum every 1-2 years or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repotting is best done in the spring.
Propagation
Propagate Trachelium caeruleum through seeds or cuttings. Seed propagation is best done in early spring, while cuttings can be taken in late spring or early summer. Use a rooting hormone to increase the success rate of cuttings.
Pruning
Prune the plant regularly to remove dead or damaged stems and to maintain its shape. Pruning also encourages bushier growth and more abundant flowering. The best time to prune is in early spring before new growth begins.
Toxicity
Trachelium caeruleum is not known to be toxic to pets or humans. However, it is always a good practice to keep plants out of reach of pets and children to avoid any accidental ingestion.
