The plant prefers slightly acidic to neutral soils with a pH range of 6.0 to 7.5. It is adaptable to a wide range of soil types including sandy, loamy, and clay soils. Adding organic matter to the soil can improve its texture and nutrient content, promoting better growth.
Cultivation
Datura inoxia P. Mill., commonly known as thorn apple, can be cultivated both indoors and outdoors. The plant can grow up to 3-4 feet tall. It requires well-draining soil with a pH range of 6.0-7.5. It thrives in full sunlight but can also grow in partially shaded areas.
Watering needs
The plant prefers moderate watering, with the soil kept moist but not waterlogged. It's important to avoid overwatering as it can lead to root rot. Underwatering can also cause the plant to wilt. Water the plant when the top inch of soil has become dry.
Fertilization
The plant requires fertilization during the growing season. Use a balanced fertilizer with an NPK ratio of 10-10-10 or 20-20-20. Fertilize the plant every two weeks during the growing season. Avoid fertilizing during the dormant season as it can affect the plant's growth.
Pruning
Pruning is essential to maintain the plant's shape and size. Prune the plant during the dormant season before new growth emerges. Remove any dead or damaged branches and trim the plant to the desired shape. Avoid pruning too much as it can affect the plant's ability to flower.
Propagation of Datura inoxia P. Mill.
