Keeping the plant in a warm and humid environment is beneficial for its growth.
Soil Requirements
Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub. requires a well-draining soil mix that is rich in organic matter. A soil mix created for African violets is perfect for this plant. The soil pH should be between 5.5 to 6.5. The soil should be kept moist but not soaked, as overwatering can lead to root rot. Fertilizing the soil with a balanced NPK fertilizer once a month during the growing season is beneficial for growth.
Cultivation Methods
Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub. is a shade-loving plant, which should be kept in a location protected from direct sunlight. The ideal temperature for its cultivation ranges from 15°C to 25°C, and the soil should have good drainage to prevent waterlogging. The plant is usually propagated by cuttings. The cuttings should be taken from healthy plants, and they should be rooted in a mixture of peat and sand. It is best to water the newly planted cuttings thoroughly but avoid overwatering.
Watering Needs
The Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub. plant should be watered regularly, but overwatering should be avoided, as it can lead to root rot. The soil should be moist but not waterlogged. Experts suggest that the soil should be allowed to dry out slightly before watering the plant. As the plant prefers humid conditions, the use of a spray bottle to moisten the foliage is recommended to increase humidity levels around the plant.
Fertilization
It is recommended that Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub be fertilized every two weeks during the growing season, which is usually from spring to fall. A balanced liquid fertilizer, with an N-P-K ratio of 20-20-20, is recommended for this plant. Over-fertilizing should be avoided, as it can lead to poor growth and reduced flowering.
Pruning
Pruning is essential for the Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub. plant to maintain a neat, compact shape and to promote flowering. Any yellow or dead leaves should be removed as soon as possible to prevent disease occurrence. Regular pruning of the plant also helps to encourage branching, which leads to more flowers. The plant can be pinched back to encourage bushiness. If the plant becomes leggy, it can be pruned back to promote new growth from the base.
Propagation of Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub.
Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub., also known as Hooker's begonia, can be propagated through various methods such as:
Division
Division is one of the easiest and successful propagation methods for Begonia cucullata. This process involves separating the plant into several sections and replanting them separately. It is essential to ensure that each piece has an ample amount of rhizomes and roots attached to it.

Common Diseases
The common diseases affecting Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub. are:
Botrytis blight:
Botrytis blight is caused by the fungus Botrytis cinerea. It causes the leaves and stems to rot and develop gray mold. To manage botrytis blight, it is essential to avoid overhead watering, reduce humidity levels, and provide adequate air circulation. Remove the affected tissues carefully before they spread to healthy tissues. Fungicides can also be used to control the fungus.
Bacterial leaf spot:
Bacterial leaf spot is caused by the bacterium Xanthomonas campestris. It causes the leaves to have yellow spots that eventually become brown. To manage bacterial leaf spot, it is crucial to avoid overwatering and overcrowding, remove infected leaves, and ensure proper sanitation during pruning. Copper fungicides can also be used to control bacterial leaf spot.
Common Pests
The common pests that affect Begonia cucullata Willd. var. hookeri (A. DC.) L.B. Sm. & Schub. are:
Spider mites:
