Bonsai Ficus Retusa
Introduction
The Ficus retusa is one of our favourite bonsai trees for beginners. Its glossy leaves, characterful trunk and forgiving nature make it a handsome, rewarding addition to the home. As a tropical plant, it enjoys warmth, bright light and a consistent routine.
Origin
Ficus retusa originates from the warm, humid regions of South and Southeast Asia. In its natural habitat, it grows as a large evergreen tree. Bonsai cultivation keeps it compact while showcasing its attractive trunk, fine branches and dense foliage.
Care Guide
Light
- Place your bonsai in bright, indirect light.
- A little gentle morning or evening sunshine is beneficial.
- Avoid harsh midday sun through glass, as it may scorch the leaves.
- Turn the pot regularly to encourage balanced growth.
- During darker British winters, move it closer to a bright window or consider using a grow light.
Watering
- Check the compost regularly and water when the surface begins to feel slightly dry.
- Water thoroughly until excess water drains from the bottom of the pot.
- Never allow the tree to stand in water.
- Avoid letting the root ball dry out completely.
- Reduce watering during winter, when growth naturally slows.
- Use room-temperature water where possible.
Temperature and Humidity
- Keep your Ficus retusa in a warm room.
- Protect it from cold draughts, radiators and sudden temperature changes.
- Do not allow the temperature to fall below approximately 12°C.
- Increase humidity by using a pebble tray or placing the tree near other houseplants.
- Light misting can help temporarily, but good watering and a naturally humid position are more effective.
Feeding
- Feed every two weeks during spring and summer with a balanced liquid bonsai fertiliser.
- Dilute the feed according to the manufacturer’s instructions.
- Reduce feeding to once a month in autumn.
- Feed sparingly, or pause feeding, during winter if the tree is not actively growing.
- Do not fertilise a dry or recently re-potted tree.
Pruning and Shaping
- Trim new shoots after they have produced six to eight leaves, cutting them back to two or three leaves.
- Remove dead, damaged or crossing branches whenever necessary.
- Use clean, sharp bonsai scissors to make neat cuts.
- Ficus trees respond well to pruning and can be shaped throughout the active growing season.
- If using wire, check it frequently—the branches thicken quickly, and wire can leave permanent marks.
Repotting
- Repot every two to three years, preferably in late spring or early summer.
- Use a free-draining bonsai compost.
- Gently trim back a small amount of congested root growth when repotting.
- Choose a pot with adequate drainage holes.
- Keep the tree warm, sheltered and evenly moist while it recovers.
Common Problems
- Yellow leaves may indicate overwatering, poor drainage or insufficient light.
- Crispy or dropping leaves can be caused by underwatering, cold draughts or sudden changes in position.
- Some leaf drop is common after bringing the plant home while it adjusts to its new surroundings.
- Watch for scale insects, spider mites and mealybugs, particularly in warm, dry rooms.
- Wipe the leaves gently to remove dust and check regularly for pests.
Pet Safety
- Ficus retusa is toxic to cats and dogs if eaten.
- Its milky sap can irritate the mouth, skin and digestive system.
- Possible symptoms include drooling, vomiting, reduced appetite and skin irritation.
- Keep the tree out of reach of pets and young children.
- Wear gloves when pruning if you have sensitive skin, and wash your hands afterwards.
- If your pet chews the plant or develops symptoms, contact your vet promptly for advice.
Our Plant Tip
