The Balfour Aralia, known botanically as Polyscias scutellaria ‘Balfouriana’, is a popular houseplant. This elegant variety is admired for its unique, rounded, scalloped leaves, which often feature deep green centers with creamy white edges, resembling miniature dinner plates. Its upright growth habit and distinctive foliage add texture and a tropical ambiance to indoor spaces.
Essential Environmental Requirements
Lighting
Balfour Aralias thrive in bright, indirect light conditions. An east or north-facing window is ideal, providing filtered sunlight without harsh, direct rays that can scorch leaves. While the plant tolerates moderate light, its vibrant variegation may become less pronounced.
Watering
Proper watering is important for Balfour Aralias. Allow the top inch or two of soil to dry completely between waterings. Overwatering can cause root rot, a common issue due to the plant’s fine root system. Ensure the pot has good drainage to prevent water accumulation. Reduce watering frequency during cooler fall and winter months as the plant’s needs decrease.
Soil
A well-draining, aerated soil mix is ideal for Balfour Aralias. A high-quality potting mix, amended with perlite or coarse sand, enhances drainage and prevents waterlogging, which is important for healthy root development. A balanced soil pH also supports nutrient uptake and overall plant vigor.
Temperature and Humidity
Balfour Aralias prefer warm, consistent temperatures, ranging from 18-29°C (65-85°F). Avoid sudden temperature changes or cold drafts, as temperatures below 15°C (60°F) can cause stress and leaf drop. This tropical plant also benefits from moderate to high humidity, ideally around 60-70%. Increase humidity by using a pebble tray, grouping plants, or employing a room humidifier.
Ongoing Care and Maintenance
Fertilizing
During the active growing season (spring and summer), fertilize Balfour Aralias regularly. Apply a balanced liquid fertilizer, diluted to half strength, monthly or every 4-6 weeks to support healthy foliage growth. Reduce or stop fertilizing entirely during fall and winter when the plant’s growth naturally slows.
Pruning
Pruning maintains the Balfour Aralia’s shape and size, encouraging bushier growth. Trim leggy stems and remove dead or yellowing leaves. Use clean, sharp scissors to minimize plant damage. Regular pruning also controls height, allowing the plant to fit well within indoor spaces.
Repotting
Balfour Aralias require repotting every two to three years, or when root-bound. Signs include roots circling the pot or significantly slowed growth. When repotting, select a container only slightly larger to prevent excess soil moisture. Spring is the best time to repot, as the plant enters its active growth phase.
Troubleshooting Common Issues
Pests and Diseases
Balfour Aralias can attract common houseplant pests like spider mites, mealybugs, and aphids. Regular inspection, especially of leaf undersides, helps early identification. Insecticidal soap or neem oil are effective treatments. Root rot, often caused by overwatering, is a common disease; good drainage is crucial. Maintaining air circulation also helps prevent fungal diseases.
General Health Concerns
Non-pest or disease issues often signal care imbalances. Yellowing leaves can indicate overwatering, underwatering, low humidity, or nutrient deficiencies. Leaf drop responds to temperature fluctuations, low humidity, or improper watering. Brown leaf tips point to low humidity, over-fertilization, or mineral buildup from tap water. Addressing the underlying environmental factor or care routine resolves these symptoms.
