How to grow chinese evergreen
Overview
Chinese evergreen (Aglaonema commutatum) is a compact, clump-forming shrub grown for its striking variegated foliage. It is a reliable filler plant that provides year-round texture and colour in shaded garden beds and containers. Key to success is providing bright indirect light and protecting it from cold snaps.
Varieties
- Aglaonema 'Silver Queen' — Silver-green leaves with dark green edges; very popular in Australian nurseries.
- Aglaonema 'Maria' — Dark green leaves with silver markings; tolerates lower light than other varieties.
- Aglaonema 'Red Siam' — Burgundy and green variegated leaves; adds a splash of colour to shaded spots.
Soil Preparation
Chinese evergreen prefers a slightly acidic to neutral pH (6.0–7.0) and a free-draining, humus-rich soil. Add coarse sand or perlite to heavy clay to improve drainage. A good quality potting mix with added organic matter works well for containers.
Growing Guide
Plant Chinese evergreen in a position with bright, indirect light and protection from harsh afternoon sun. Use a free-draining potting mix or garden soil enriched with organic matter. Space plants 30–50 cm apart for a dense groundcover effect. In cooler districts, wait until after the last frost to plant outdoors, or grow in a pot that can be moved to shelter. Water moderately, allowing the top few centimetres of soil to dry out between waterings.
Care
Feed with a balanced slow-release fertiliser in spring and summer. Prune only to remove yellow or damaged leaves; keep the soil consistently moist but not wet. Repot every 2–3 years if the plant becomes pot-bound, using a fresh free-draining mix.
Companion Planting
Pair Chinese evergreen with other shade-loving foliage plants such as ferns, peace lilies (Spathiphyllum), and calatheas. Avoid planting near sun-loving herbs or vegetables that require full sun, as they will compete for light and moisture.
Common Pests & Risks
Mealybugs and scale are common on Chinese evergreen; treat with a soft cloth dipped in soapy water or apply horticultural oil. Root rot can occur if soil stays too wet; ensure free drainage and reduce watering in winter. Spider mites may appear in dry air; increase humidity by misting or grouping plants.
Troubleshooting
Yellow leaves: overwatering or poor drainage; let soil dry out more between waterings. Brown leaf edges: low humidity or too much direct sun; move to a shadier spot and increase humidity. Drooping leaves: underwatering or cold stress; water thoroughly and protect from cold drafts. Leggy growth: too little light; move to a brighter spot with indirect light. Sticky residue on leaves: likely a scale or mealybug infestation; treat with insecticidal soap.
