Ficus carmona, commonly known as the Carmona Bonsai or Fukien Tea Tree, is a captivating evergreen bonsai celebrated for its glossy foliage, elegant trunk structure, and year-round visual interest. Native to Southeast Asia and parts of China, this bonsai species is a favourite among enthusiasts for its refined appearance and forgiving nature once established.

Its small, oval, deep-green leaves have a glossy surface with fine white speckling, creating a delicate, textured look. The tree often produces tiny white flowers throughout the year, which may develop into small red berries, adding an extra layer of charm and contrast. Its bark is naturally gnarled and aged-looking, giving even young specimens the appearance of maturity and strength.

Perfect for both beginners and experienced growers, the Ficus carmona (Retusa) Bonsai combines elegance, tradition, and resilience — a living sculpture that captures the timeless beauty of nature in miniature form.

Ficus carmona (Retusa) – Care Guide

Light

Prefers bright, indirect light and benefits from a few hours of morning or late afternoon sun. Too little light can cause leggy growth and sparse foliage, while intense midday sun can scorch the leaves. A bright windowsill or conservatory is ideal. In low-light conditions, consider supplementing with a grow light.

Watering

Keep the soil evenly moist but never waterlogged. Water thoroughly when the top 2–3 cm of soil feels dry. Avoid letting the root ball dry out completely. Use room-temperature water and ensure good drainage, as the Carmona is sensitive to overwatering. In winter, reduce watering frequency but maintain light moisture.

Temperature and Humidity

Temperature: Thrives between 18–28 °C and should be protected from temperatures below 15 °C. Avoid sudden drafts or changes in temperature.
Humidity: Prefers moderate to high humidity (50–70%). Mist regularly, especially during dry indoor months or when using central heating.

Soil and Potting

Use a free-draining bonsai mix containing akadama, pumice, and fine bark. This ensures excellent aeration and prevents root rot. Repot every 2–3 years in late spring to early summer, trimming up to one-third of the roots if necessary. Always repot into a shallow bonsai pot with good drainage holes.

Feeding

Feed every 2–4 weeks during the growing season (spring through autumn) with a balanced liquid bonsai fertiliser. Reduce feeding in winter when growth slows. Alternate between organic and liquid fertilisers for best results.

Pruning and Maintenance

Regular pruning maintains the tree’s compact shape and encourages branching. Trim new shoots back to 2–3 leaves once they have developed 6–8 leaves. Major structural pruning is best done in late spring. Pinch off any large leaves to maintain the fine, delicate appearance typical of bonsai. Clean the leaves occasionally to remove dust and promote photosynthesis.

Growth and Maturity

A slow to moderate grower, Ficus carmona develops a thick, gnarled trunk with time, enhancing its aged aesthetic. With proper care, it can live for decades, continually refining its character and form. The plant can flower multiple times a year, producing small white blooms and bright red berries.

Common Issues

• Yellowing leaves: Overwatering or poor drainage.

• Leaf drop: Sudden change in light or temperature.

• Pale leaves: Nutrient deficiency or insufficient light.

• Pests: Occasionally affected by scale or whitefly — treat promptly with neem oil or insecticidal soap.

Background and Benefits

The Carmona, or Fukien Tea Tree, has been cultivated for centuries in China and Japan as a symbol of wisdom, patience, and balance. Named after the Fujian province in China, it was traditionally grown indoors as a meditation companion, admired for its miniature proportions and natural elegance.

As a bonsai, Ficus carmona offers both beauty and mindfulness — encouraging regular observation and gentle care. It also purifies indoor air, contributing to a calm, serene environment.
