Cultivation Techniques
Soil Requirements
Rex Begonia plants require well-draining soil that is rich in organic matter.
A mixture of peat moss, perlite, and vermiculite is recommended for optimal growth.
It is important to ensure that the soil is never allowed to dry out completely, as this can cause the leaves to wilt and drop.
Watering Practices
Rex Begonias prefer to be kept consistently moist, but not waterlogged.
It is important to water the plant thoroughly, allowing excess water to drain away, and then allow the soil to dry out slightly before watering again.
Overwatering can lead to root rot, while underwatering can cause the leaves to become dry and brittle.
Light and Temperature
Rex Begonias thrive in bright, indirect light. Direct sunlight can scorch the leaves, while too little light can cause the plant to become leggy and weak.
A temperature range of 60-75°F (15-24°C) is ideal for these plants.
They are sensitive to temperature fluctuations, so avoid placing them near drafts or heating/cooling vents.
Overall, Rex Begonias are relatively easy to care for and make excellent houseplants.

Leaf cuttings can also be taken by selecting a healthy, mature leaf and cutting it into sections with a sharp, clean knife.
Each section should have a main vein and be around 2-3 inches in length.
Place the cuttings on top of a moist soil mix, press down lightly, and cover with plastic to maintain humidity.
New plants should start to emerge within a few weeks.

Avoid overwatering and allow the soil to dry out slightly between waterings to prevent root rot.
Regular pruning can help maintain a bushy, compact shape and promote new growth.
