Additionally, Begonia ampla Hook.f. benefits from regular fertilization during the growing season to promote healthy growth and blooming.
Light Requirements
Begonia ampla Hook.f. prefers to grow in areas with partial shade, receiving filtered sunlight in the morning or the afternoon. Direct sunlight can cause damage to the leaves and slow down the growth of the plant. It is recommended to place the plant near a north-facing window in areas with high temperatures, and under bright fluorescent lighting or grow lights if the plant is placed indoors.
Temperature Requirements
The ideal temperature range for the Begonia ampla Hook.f. is between 18°C to 26°C. When the temperature rises above 32°C, it is necessary to increase the humidity level around the plant. The plant can withstand temperatures as low as 10°C, but it is not recommended to expose it to temperatures below 4°C, which can cause serious damage to the plant.
Soil Requirements
The soil for the Begonia ampla Hook.f. should be slightly acidic with a pH range between 5.5 to 6.5. The soil should be well-draining to prevent waterlogging, which can cause root rot. Adding perlite or sand to the soil can help with drainage. It is also recommended to add organic compost to the soil for better growth. The plant can grow well in a mixture of peat moss, perlite, and vermiculite in equal parts.
Cultivation Methods for Begonia ampla Hook.f.

- Cut the stem just above a leaf node to encourage new growth.
- Disinfect the pruning tool after each use.
By following these tips, you can grow and care for Begonia ampla Hook.f. successfully.
Propagation of Begonia ampla Hook.f.
Begonia ampla Hook.f., commonly called the wax begonia, is usually propagated through stem cuttings and seeds. The following are the propagation methods:
Propagation by stem cuttings
Stem cuttings taken from a healthy parent plant is the most reliable way to propagate Begonia ampla Hook.f. The stem must be at least 3-4 inches long and must have multiple nodes. A clean and sharp knife or pruning shear must be used to avoid damaging the cutting.
The lower leaves of the cutting must be removed, and a rooting hormone should be applied at the base of the stem to encourage rooting. The cutting must then be planted in a well-draining potting mix and kept moist. After a few weeks, new growth will emerge, indicating that the cutting has rooted successfully.
Propagation by seeds
Begonia ampla Hook.f. can also be propagated from seeds. The seeds must be collected from a mature plant and sown in a tray or small pots, covering them lightly with potting mix. The tray or pot should then be covered with a plastic bag to maintain humidity and placed in a warm and bright location.
After a few weeks, the seeds will germinate, and the plastic bag can be removed. The seedlings must be kept moist and gradually acclimatized to their surroundings before transplanting them to larger pots or outdoors.
Disease and Pest Management for Begonia ampla Hook.f.
Begonia ampla Hook.f. is a beautiful and popular plant due to its large, eye-catching leaves and vibrant flowers. However, like any other plant, it is susceptible to several diseases and pest infestations. Here's some information about the common diseases and pests affecting the Begonia ampla Hook.f. and ways to manage them.
Diseases
Bacterial leaf spot: This disease appears as small, dark lesions on the leaves, which may enlarge and merge to form irregular shapes. The infected leaves may turn yellow and drop from the plant, severely affecting its growth. To manage this, remove the affected leaves and disinfect any tools used for pruning. Provide adequate air circulation and avoid splashing water on the foliage.
Botrytis blight: This fungal disease results in the formation of gray mold on the leaves and flowers. It often occurs in humid conditions and may spread rapidly across the plant. To manage this, remove the infected parts immediately, improve air circulation around the plant, and avoid overwatering.
Pests
Spider mites: These pests are tiny and can be recognized by webs and yellow speckles on the leaves. They suck the sap from the leaves, depriving the plant of nutrients. Use a miticide to manage this pest infestation, and make sure to cover the entire leaf surface when applying pesticides.
Thrips: These tiny insects are hardly visible, but their presence can be recognized through their speckles and scars on the leaves. They suck the sap from the plant, causing its leaves to curl and become distorted. To manage this pest, use sticky traps, or apply neem oil or insecticidal soap to the plant foliage.
Early detection of diseases and pest infestations is critical for efficient management. By taking preventive measures, such as maintaining good air circulation, avoiding overwatering and regularly inspecting the plant for signs of pest infestations and diseases, you can keep your Begonia ampla Hook.f. healthy and thriving.
