Ficus retusa aka Indian Laurel

Ficus retusa, or laurel fig, belongs to the mulberry family, Moraceae. Its native range runs from southern Borneo to Java. It grows there in a wet tropical climate. This evergreen tree forms a broad crown with spreading branches. In cooler climates, people grow it as a houseplant. It also suits a warm greenhouse or conservatory.

The RHS gives a cultivated height of 8–13 feet (2.5–4 metres). Its listed spread is 3–5 feet (1–1.5 metres). The same account describes larger trees reaching 33 feet (10 metres). Plants take about 10–20 years to reach their mature size. Thick aerial roots add to the tree's form. The leaves grow close together and have a broad, oval shape. Each leaf is thick, dark green, and glossy. Leaves measure about 4–5 inches (0.10–0.12 metres) long. Mature trees in hot climates bear clusters of round figs. These start purple and turn black as they ripen.

Give this fig full sun or bright, filtered light. The RHS lists loam and houseplant compost as growing media. Keep the soil moist, but make sure excess water drains away. It accepts acid, neutral, or alkaline soil. Choose a sheltered spot for outdoor summer growth. Its RHS hardiness rating is H1B. In the UK, this means outdoor growth is limited to summer. The rating covers minimum temperatures of 50–59°F (10–15°C).

Water moderately during spring and summer, then reduce watering in winter. Feed monthly with a high-nitrogen fertiliser during the growing season. Add fresh compost at the surface each year. Repot the plant every two to three years. Indoor plants may need winter pruning to limit their size. The tree also lends itself to bonsai training. Propagate it from semi-ripe cuttings or leaf-bud cuttings. Take these in spring or summer, and provide heat from below.

Indoor pests can include red spider mites and thrips. Mealybugs and scale insects may also attack the plant. The RHS reports few disease problems in houseplants grown in cold climates. Its leaves and aerial roots provide interest throughout the year. Handle the plant with care, as it can cause skin allergies. Wear gloves and other protection when working with it. The supplied evidence does not establish that its figs are edible.
