Alocasia cuprea ‘Red Secret’ – Care Guide

Light

Thrives in bright, indirect light. Too much direct sunlight can burn or dull the glossy leaves, while too little light can lead to slower growth and muted colour. East- or north-facing rooms with filtered light are ideal.

Watering

Keep the soil lightly moist but never soggy. Water when the top 2–3 cm feels dry, ensuring good drainage at all times. Alocasia ‘Red Secret’ dislikes standing water but is equally sensitive to drying out completely. Reduce watering slightly during winter dormancy.

Temperature and Humidity

Temperature: Prefers warmth between 18–28 °C; avoid drafts or temperatures below 15 °C.
Humidity: High humidity (60–80%) is essential to maintain leaf gloss and prevent crisping edges. Mist regularly, use a humidifier, or place on a pebble tray for optimal conditions.

Soil and Potting

Use a loose, moisture-retentive yet free-draining aroid mix — compost combined with perlite, orchid bark, and coco coir works perfectly. Repot every 1–2 years in spring to refresh the soil and encourage healthy root growth.

Feeding

Feed every 4–6 weeks in spring and summer with a diluted, balanced liquid fertiliser. Avoid over-fertilising, which can damage the roots and cause leaf discolouration. Suspend feeding during autumn and winter when growth naturally slows.

Pruning and Maintenance

Remove older or damaged leaves at the base to maintain a neat appearance. Wipe the large, glossy leaves gently with a damp cloth to remove dust and enhance their metallic sheen. Rotate occasionally for even light exposure and balanced growth.

Growth and Maturity

A slow to moderate grower, Alocasia ‘Red Secret’ typically reaches 30–50 cm in height and spread indoors. Each new leaf unfurls with a coppery-pink tone before deepening to rich burgundy and bronze hues. During winter dormancy, it may temporarily drop older leaves — this is normal; simply reduce watering and wait for new growth in spring.

Common Issues

• Yellowing leaves: Overwatering or poor drainage.

• Brown edges: Low humidity or inconsistent watering.

• Drooping leaves: Cold temperatures or too-dry soil.

• Pests: Occasionally affected by spider mites or thrips — treat with neem oil and maintain high humidity.

Background and Benefits

Native to the rainforests of Borneo, Alocasia cuprea is revered for its naturally metallic foliage — a feature evolved to reflect intense tropical sunlight. The ‘Red Secret’ cultivar intensifies these tones, producing jewel-like leaves that range from silvery copper to deep garnet red.

In interiors, Alocasia ‘Red Secret’ is both decorative and symbolic. Its glossy, heart-shaped leaves represent prosperity, vitality, and transformation, bringing both energy and elegance to modern homes.
