How to Care for Begonia rex 'Odissi'
Placement

Best positioned in a warm, humid area with good air circulation.
Avoid exposure to cold drafts, heating vents, or sudden temperature fluctuations.

Light Requirements

Prefers bright, indirect light to maintain vibrant leaf colors.
Avoid direct sunlight, which can scorch delicate foliage.
Can adapt to artificial grow lights if natural light is insufficient.

Watering

Allow the top 2–3 cm of soil to dry before watering.
Water at the base to avoid wetting the leaves and prevent fungal infections.
Use room-temperature water to prevent temperature shock.

Humidity & Temperature

Requires humidity above 50%; ideal range is 60–70%.
Thrives in temperatures between 18–24°C; avoid exposure below 15°C.
If air is too dry, use a humidifier or group plants together to create a microclimate.

Soil & Potting

Use a light, well-draining mix rich in organic matter (peat, perlite, bark).
A shallow, wide pot is ideal due to the rhizomatous root system.
Ensure the pot has drainage holes.

Repotting

Repot every 1–2 years or when roots outgrow the container.
Handle roots carefully, as they are delicate and prone to damage.

Fertilization

Feed every 4 weeks with a balanced liquid fertilizer at half strength.
Avoid over-fertilizing to prevent weak, leggy growth.

Propagation

Leaf Cuttings: Cut a healthy leaf and place it in moist soil or water until roots develop.
Rhizome Division: Divide rhizomes and replant in fresh soil for quicker propagation.

Semi-Hydroponics Suitability

Can adapt to semi-hydroponics with LECA if moisture balance is properly monitored.

Pruning

Trim old, damaged leaves regularly to promote healthy new growth.
Pinching back stems encourages bushier, more compact growth.

Common Problems & Solutions
Pests

Spider Mites, Mealybugs, Fungus Gnats: Regularly inspect leaves and soil. Treat infestations with neem oil or insecticidal soap.

Leaf Issues

Browning Edges: Usually caused by low humidity or underwatering. Increase moisture levels.
Yellowing Leaves: Often due to overwatering or poor drainage. Adjust watering schedule and improve soil aeration.
Drooping Leaves: May indicate temperature stress, low humidity, or overwatering. Maintain stable conditions.

Root Rot

Overwatering or compact soil can lead to root rot.
Remove affected roots, improve aeration, and adjust watering habits.

Fungal Diseases

Powdery Mildew, Botrytis (Gray Mold): Improve air circulation and keep foliage dry. Use fungicide if needed.

Additional Considerations

Support Needs: Not a climber but benefits from light support to prevent sprawling.
Winter Care: Growth may slow but does not require dormancy care.
Handling: Delicate foliage is prone to tearing—handle carefully when repotting or moving.
