Begonia ‘Benitochiba’ is a captivating perennial hybrid, often grown as a houseplant, known for its distinctive foliage. Its large, palmately-divided leaves display a striking silvery hue with dark green vein markings. Younger leaves can also show a purplish-pink flush. This Rex Begonia can reach up to 60 centimeters tall and spread about 50 centimeters.
Begonia ‘Benitochiba’ Care
Light
Begonia ‘Benitochiba’ thrives in gentle morning sunlight. Shield it from harsh afternoon rays to prevent leaf burn. While it tolerates full shade, bright, indirect light best maintains its vibrant coloration and lush growth.
Watering
Begonia ‘Benitochiba’ prefers consistently moist, but not waterlogged, soil. Allow the top layer to dry before rewatering. When watering, saturate the soil thoroughly and ensure excess water drains completely to prevent root rot.
Overwatering causes root rot and fungal issues, while insufficient water leads to drooping stems and wilting leaves. Reduce watering to about once every three to four weeks during winter. Using room-temperature water is beneficial.
Humidity
Begonia ‘Benitochiba’ thrives in high humidity, ideally 40% to 70% relative humidity. To increase moisture, mist the plant, use a pebble tray, or group it with other plants. Insufficient humidity causes dry, wilted leaves or crispy edges. Ensure adequate air circulation to prevent fungal issues, even with high humidity.
Soil
Begonia ‘Benitochiba’ needs a well-drained, airy, and organically rich soil mixture. It prefers a slightly acidic environment, with a pH range of 5.5 to 6.2. Soilless media often provide optimal results. A common mix includes two parts peat moss with one part vermiculite, bark, or perlite. Excellent drainage is important to prevent water accumulation and root rot.
Fertilizing
During active growth from spring through early fall, Begonia ‘Benitochiba’ benefits from regular fertilization. It is a heavy feeder, especially when blooming. Apply a balanced liquid fertilizer, such as a 20-20-20 blend, monthly or bi-weekly for potted plants. Proper dilution is important to prevent leaf damage, as it is sensitive to excessive fertilizer. Reduce or stop fertilization during late fall and winter.
Temperature
Begonia ‘Benitochiba’ thrives best between 17°C and 25°C (62°F and 77°F). While it can withstand extremes from 5°C (41°F) to 43°C (110°F), these conditions cause stress. A minimum winter temperature of 13°C (55°F) is recommended for health. Cold exposure can cause leaf discoloration or drop, while excessive heat leads to wilting and scorched foliage. Avoid sudden temperature changes and cold drafts.
Propagating Begonia ‘Benitochiba’
Propagating Begonia ‘Benitochiba’ is effective using stem or leaf cuttings.
Stem Cuttings
Stem cuttings are generally successful year-round, rooting fastest from late spring to early summer. Select a healthy 10-15 cm segment, cutting just below a node. Remove lower leaves, leaving two or three at the top, then insert into moist, well-draining potting mix. High humidity and indirect light encourage root development within weeks.
Leaf Cuttings
Leaf cuttings are another viable method, particularly in spring and fall. Choose a mature, healthy leaf and make small incisions along the main veins on its underside. Place the leaf flat onto a moist, free-draining compost mix, such as multi-purpose compost and perlite. New plantlets emerge from these incisions with warmth and consistent moisture.
Common Problems and Pests
Begonia ‘Benitochiba’ can face issues related to environmental conditions.
Leaf discoloration or drop may signal temperature extremes, overwatering, underwatering, or insufficient light. Wilting and scorched leaves often point to overheating or inadequate moisture. Crispy brown spots or edges can result from low humidity, direct heat, temperature fluctuations, or excessive fertilizer.
Root rot is caused by overwatering or poorly draining soil. Fungal issues like powdery mildew, appearing as white spots on leaves, can occur with poor air circulation or high humidity without proper airflow. Botrytis blight, or gray mold, may appear as papery brown flowers and fuzzy gray masses, particularly in humid conditions.
Several common houseplant pests can affect Begonia ‘Benitochiba’.
- Aphids are tiny, pear-shaped insects that can cause leaves to yellow.
- Spider mites, microscopic pests, create fine webs and lead to yellow or speckled spots, thriving in warm, dry environments.
- Mealybugs appear as white, cottony clusters and can result in yellowing leaves and stunted growth.
- Thrips are slender insects that cause silvery streaks or distorted growth.
- Whiteflies are small, moth-like insects that feed on plant sap.
For treatment, insecticidal soap or neem oil can be effective solutions.
