Begonia erythrophylla, also known as beefsteak begonia, is a foliage lover’s dream. This unique plant has a rich history and is relatively easy to care for, making it a perfect addition to any indoor or outdoor garden.

What Makes Begonia erythrophylla Unique?

It’s not easy to put into words what makes begonia erythrophylla so special, but any plant collector will tell you that it is truly a rare gem. With its captivating leaves and vibrant flowers, this plant stands out among the rest.

Begonia erythrophylla is a hybrid of two rhizomatous begonias, the Begonia manicata and Begonia hydrocotylifolia. This combination makes it adaptable to both mild temperatures and tropical environments. No matter where you choose to grow it, this plant will thrive.

Caring for Begonia erythrophylla

Taking care of begonia erythrophylla is a breeze, as long as you provide it with the right conditions. Here are the essential care tips:


This variety of begonia can tolerate a range of light conditions. It can handle full sun if planted outdoors, or partial sun/indirect light if kept indoors. Aim for around 35,000 lux of medium sunlight or 55,000-60,000 lux for full light.

If you choose to keep it indoors, place it in a bright room with sunlight from sunrise till noon. If your home lacks natural light, consider using grow lights as a supplement.


In the initial growth phase, be mindful of watering the plant more frequently to keep the soil moist. Once it has established itself and grown taller, water it when the soil becomes dry. Remember, begonias enjoy well-drained soil to prevent root rot.

When watering begonia erythrophylla, direct the water as close to the soil as possible to avoid wetting the leaves. Bottom watering can be beneficial when the plant is indoors.

Begonias, including beefsteak begonia, are known for their hardiness. It can tolerate temperatures ranging from 45-85℉ (7-29℃). To maintain the ideal temperature range, avoid placing it near air conditioners or heaters that can dry out the air.


Beefsteak begonia can handle varying humidity levels, with an ideal range of up to 50%. If kept indoors, low humidity might be an issue. Place the plant in your bathroom during the winter to benefit from the steam of hot showers. Grouping plants together can also increase humidity levels. Consider using a humidifier for steady humidity levels.


Choosing the right soil mix is crucial for begonia erythrophylla. Opt for a fluffy, light, and acidophilic soil mix to ensure proper drainage and maintain a soil pH level around 6.5. Adding orchid bark to the mix can provide the ideal pH level of 7 that begonias love.


Fertilize begonia erythrophylla during the spring and summer months using a general fertilizer with a nitrogen-phosphorus-potassium (NPK) formula. Dilute the fertilizer to 50% of the recommended dose, as begonias have a small root system. Apply the fertilizer every two weeks, ensuring careful dilution to avoid burning the plant.

Potting & Repotting

Repot begonia erythrophylla when you notice roots emerging from the pot bottom. Choose a pot with drainage holes, slightly larger than the current pot. Gently untangle the roots before placing them in a mixture of pebbles, perlite, and orchid bark. Fill the pot with well-drained soil to ensure proper growth.


Pruning is essential to stimulate new growth and maintain the plant’s health. Trim any dead or brown leaves using sterilized, sharp tools. This will help prevent disease and encourage new foliage.


Beefsteak begonia can be propagated through stem cuttings placed in water or by planting rhizomatous leaves directly into soil. Handle the roots and stems gently when propagating, and change the water frequently if using water propagation.

Common Problems of Begonia erythrophylla

Like any plant, begonia erythrophylla may encounter some issues. Bacterial leaf spots and botrytis blight are the most common problems.

Bacterial Leaf Spots

Black or dark brown spots on the leaves indicate bacterial leaf spots. Excessive water on the leaves can make them susceptible to bacteria and can lead to yellowing and the spread of infection. To address this issue, sterilize scissors and remove the infected leaves.

Botrytis Blight

Botrytis blight can occur when humidity levels are high and temperatures are cold. Affected leaves will turn brown and appear ready to fall off. Remove infected leaves and dispose of them separately to prevent the spread of disease. Neem oil can be effective in preventing these issues.


Begonia erythrophylla is not immune to pests. Aphids and slugs/snails are the most common pests affecting this plant.


White bugs on the leaves indicate an aphid infestation. A mixture of water, dish soap, and rubbing alcohol can help eliminate them. For severe infestations, seek assistance from a local plant nursery.


While harmless to the plant, slugs and snails can leave unsightly bite marks on the leaves. Remove them manually and apply neem oil to discourage their return.

Growing Problems

If you notice a lack of new leaves during spring and summer, the plant may have growth problems. Ensure proper drainage, use fresh soil, and consider repotting if necessary.

Toxicity of Begonia erythrophylla

Beefsteak begonia is toxic to pets but poses minimal risk to humans. The sap from the stems and leaves can cause digestive issues and vomiting in pets. However, it is important to handle the plant with care to prevent contact with the sap.
