Rex begonias are a popular houseplant that has become a staple in many indoor gardens. They are known for their striking foliage that comes in a variety of colors and patterns. Rex begonias can be a bit finicky, but with proper care, they can grow into healthy, beautiful plants. In this article, we will provide a guide to rex begonia care that will help you achieve optimal growth and vibrant foliage.

Lighting

Rex begonias thrive in bright, indirect light. They should not be placed in direct sunlight, as this can cause the leaves to burn. If your rex begonia is receiving too much light, the leaves will turn yellow and the plant will become weak. On the other hand, if your plant isn't receiving enough light, the leaves will become pale and thin. A north or east-facing window is ideal for rex begonias, as they will receive bright, indirect light.

Watering

Rex begonias prefer to be kept moist but not wet. They have a shallow root system, which makes them susceptible to root rot if they are overwatered. When watering your rex begonia, make sure to water the soil, not the leaves. This will prevent water from sitting on the leaves, which can cause fungal infections. Water your rex begonia when the top inch of soil feels dry to the touch. It's essential to ensure that the soil is well-draining and never becomes waterlogged.

Temperature

Rex begonias prefer temperatures between 60-75 degrees Fahrenheit. They don't like extreme temperature changes or drafts, which can cause stress to the plant. It's best to keep them away from heating or cooling vents and doorways.

Fertilizing

Fertilizing is an important part of rex begonia care. They require a balanced, water-soluble fertilizer once a month during the growing season (spring and summer). Avoid fertilizing during the fall and winter months, as this is the plant's dormant period. Overfertilizing can cause damage to the plant, so it's important to follow the instructions on the fertilizer package carefully.

Potting

Rex begonias prefer to be root-bound, so it's best to choose a pot that's just a bit larger than the root ball. It's essential to ensure that the pot has drainage holes to prevent the soil from becoming waterlogged. Use a well-draining potting mix that contains peat moss, perlite, and vermiculite.

Propagation

Rex begonias can be propagated through leaf cuttings. Choose a healthy leaf and cut it close to the stem. Dip the cut end into rooting hormone and plant it in a well-draining potting mix. Cover the pot with plastic wrap to create a humid environment, and place it in bright, indirect light. The cutting should root in a few weeks.

Verdict

Rex begonia care requires proper lighting, watering, humidity, temperature, fertilizing, potting, and propagation techniques. With the right care, rex begonias can grow into healthy, vibrant plants that will bring joy to your indoor garden for years to come.
