Philodendron ‘Red Sun’ – Care Guide

Light

Thrives in bright, indirect light, which enhances its red pigmentation and encourages strong growth. It can tolerate moderate light but may lose colour intensity in lower light conditions. Avoid direct sun, which can scorch the tender new leaves.

Watering

Keep the soil lightly moist but not waterlogged. Water when the top 2–3 cm of soil feels dry to the touch. Overwatering can cause root rot, while prolonged dryness may result in curling or browning leaves. In winter, reduce watering slightly to match the plant’s slower growth rate.

Temperature and Humidity

• Temperature: Prefers warmth between 20–30 °C; avoid temperatures below 16 °C.

• Humidity: Enjoys moderate to high humidity (50–70%). Regular misting, a humidifier, or grouping with other tropicals will keep the foliage lush and glossy.

Soil and Potting

Use a well-draining, nutrient-rich aroid mix, such as compost blended with orchid bark, perlite, and coco coir. This ensures airflow while maintaining gentle moisture. Repot every 1–2 years in spring to refresh the mix and give room for root expansion.

Feeding

Feed every 4–6 weeks during the growing season with a diluted, balanced fertiliser or a foliage-specific formula high in nitrogen and magnesium. Avoid over-fertilising, which can burn the roots or dull leaf colour. Suspend feeding in winter.

Pruning and Maintenance

Remove older or damaged leaves at the base to maintain a clean, compact appearance. Wipe leaves regularly with a soft, damp cloth to remove dust and accentuate their natural shine. Rotate the pot every few weeks for even light exposure and uniform colouration.

Growth and Maturity

A moderate grower, Philodendron ‘Red Sun’ typically reaches 40–60 cm in height and spread indoors. Its self-heading, non-vining habit makes it a perfect tabletop or floor plant for smaller spaces. Over time, it develops a robust clump of colourful foliage that transitions gracefully from fiery red to glossy green, offering year-round visual interest.

Common Issues

• Faded colour: Insufficient light.

• Yellow leaves: Overwatering or poor drainage.

• Brown tips: Low humidity or inconsistent watering.

• Pests: Occasionally thrips or mealybugs; treat promptly with neem oil or insecticidal soap.

Background and Benefits

Philodendron ‘Red Sun’ is a modern hybrid bred for colour intensity, compact growth, and adaptability. It originates from tropical breeding programmes that focused on developing self-heading Philodendrons with vivid pigmentation and low-maintenance traits.

Like other Philodendrons, it is a natural air purifier, removing common indoor toxins while adding oxygen and visual warmth. Its vibrant hues and structured growth make it a favourite choice for designers and plant enthusiasts looking to introduce colour and vitality into bright living spaces.
