Ficus retusa, also called Ficus microcarpa, grows naturally 50 to 80 feet high and equally wide with dark green, glossy and leathery leaves. The tree survives in temperatures between 25 degrees and 115 degrees F. Ficus retusa is often grown on a smaller scale as an indoor plant. Ficus retusa will grow quickly on its own. To care for the plant, create the right environment.
Plant ficus retusa in an area with full or partial sun and well-drained soil. The plant survives in various soil types and can withstand some salt spray. Plant it at least 10 feet away from sidewalks, as the roots grow near the surface and can cause damage. For indoor plants, plant in a pot with high-quality potting soil.
Water ficus retusa regularly, keeping it moist until it establishes itself. Gradually decrease watering, allowing the soil to dry slightly between waterings. Keep watering regularly during the growing season and stop when the weather cools so the tree can go dormant.
Fertilize ficus retusa with a complete fertilizer of the ratio 3:1:2. The three numbers represent the nitrogen, phosphorus and potassium elements in the fertilizer, respectively. Fertilizer packages will note this on the package. For example, a good Ficus retusa fertilizer may have the numbers 18-6-12 on it. This plant will grow quickly and vigorously on its own so only fertilize if growth seems weak.
Prune ficus retusa to keep the plant in check. If the branches droop too low, clip them with pruning shears. Shape this tree into a hedge or screen if you wish.
