The Ficus bonsai is a strictly indoor tree, thriving in warm, bright environments away from cold drafts or sudden temperature changes. It should be placed in a well-lit spot that receives several hours of indirect sunlight daily, such as a windowsill or bright room. Ficus appreciates high humidity, so avoid placing it near radiators or heating vents, which can dry out the air. To maintain ideal conditions, consider using a humidity tray or misting the foliage regularly, especially during winter months when indoor air tends to be drier.
The temperature of the room should be kept relatively constant, and make sure you keep it away from central heating and cold draughts, as this can dry out the root base. However, they will appreciate being placed outside during the summer to allow new growth, as long as temperatures do not drop below 15 °C. The ficus also benefits from higher humidity levels and will not develop aerial roots without them. Heightened humidity can be achieved by using a mister to spray the leaves, as well as placing a gravel tray under the pot to create a more humid microclimate around the tree.
One of the reasons Ficus is such a beginner-friendly bonsai is that its larger leaves store more water than many small-leafed or needle bonsai species. This gives it a bit more resilience if watering is missed for a day or so. However, regular watering is still essential for healthy growth. Allow the top inch of soil to dry out slightly before watering thoroughly. Be sure the pot drains well and never allow the roots to sit in standing water. In drier conditions or during active growth periods, it may require more frequent watering.
If you are a first-time bonsai owner, another way to water is by submerging the entire pot in water until the bubbles stop. If you choose this method, be aware that your bonsai may not need watering for another two to four days, but this will depend on the factors mentioned above, such as soil type, pot size and climate.
Ficus bonsai benefit from regular feeding every two to four weeks during their growing season, typically from spring through early autumn. You can start adding Chrysal Liquid Bonsai Feed to your water from March until October and use it weekly. Use Naruko Fertiliser Slow Release Bonsai Feed once every one to two months. In winter, when growth slows down indoors, you can reduce fertilising to once a month or stop temporarily if the tree is not producing new growth. However, if kept warm and in good light, the Ficus may continue growing slowly year-round and can be fed sparingly.
The Ficus bonsai responds well to regular pruning, which helps maintain its shape and encourages denser foliage. New shoots can be pruned back to 2–4 leaves once they’ve developed 6–8 leaves. This will help maintain the bonsai’s compact silhouette. The tree can be wired, though care must be taken as the bark can be sensitive. Wiring is most effective during periods of active growth and should be checked regularly to prevent wire marks. The Ficus is also notable for producing aerial roots in humid environments, which can be encouraged to grow down toward the soil, adding character and visual interest.
Training your bonsai using wiring is best done during the late spring and summer months growing period when the stems and branches are easier to bend. Thin and medium ficus branches are easy to manipulate due to their flexibility. We recommend using wires with a thickness that matches the thickness of the branch: if the wire you choose is too thick, you will damage the bark. If it is too thin, it won’t be effective.
Repot your Ficus bonsai every 2–3 years, ideally in spring or early summer when the tree is most vigorous. This helps refresh the soil and prevent the roots from becoming pot-bound. Use a well-draining bonsai soil mix that retains some moisture but doesn’t stay soggy. During repotting, gently prune back the roots as needed—Ficus tolerates root pruning well. After repotting, keep the tree in a warm, sheltered spot with moderate light and increased humidity to help it recover quickly.
With its year-round evergreen foliage, high tolerance to indoor conditions, and forgiving nature, the Ficus bonsai is a superb choice for anyone looking to start their bonsai journey. When provided with humidity, warmth, and consistent care, it can thrive and develop into a stunning indoor centrepiece for years to come.
Trees that are ready for repotting will require root pruning, a suitable new pot and appropriate soil mix.
When repotting, do not cut back the root mass by a large amount, and choose a well-draining soil mix that has a neutral or slightly higher PH value of 5-6, but not over 7. We tend to use a mixture of different speciality bonsai soils on our trees. Every species is different, so please contact us for free soil-mix advice or to take advantage of our repotting service.

Propagating a Ficus bonsai tree is a way of creating new Ficus bonsai trees from existing ones. Propagating can be done by using cuttings, seeds, or air layering. Cuttings are the easiest and most common method of propagating a Ficus bonsai tree. Cuttings involve taking a healthy branch from a Ficus bonsai tree, cutting it at an angle, and planting it in moist soil or water. Cuttings can root in a few weeks, and then be transferred to a pot and trained as a bonsai. Seeds are another method of propagating a Ficus bonsai tree, but they are more difficult and time-consuming. Seeds involve collecting the fruits from a Ficus bonsai tree, extracting the seeds, and sowing them in moist soil. Seeds can take months or years to germinate, and then require a lot of care and patience to grow into a bonsai. Air layering is a more advanced method of propagating a Ficus bonsai tree, but it can produce larger and more mature bonsai. Air layering involves making a cut on the trunk or branch of a Ficus bonsai tree, wrapping it with moist sphagnum moss and plastic, and waiting for roots to form. Air layering can take several months, and then the rooted section can be cut off and potted as a separate bonsai.
A Ficus bonsai tree can offer many benefits for your home and your well-being. A Ficus bonsai tree can purify the air in your home, as it can absorb harmful toxins and release oxygen. A Ficus bonsai tree can also reduce stress and anxiety, as it can create a calming and relaxing atmosphere. A Ficus bonsai tree can also stimulate your creativity and concentration, as it can inspire you to learn new skills and appreciate nature. A Ficus bonsai tree can also beautify your home, as it can add colour and charm to any space.
A Ficus bonsai tree can also pose some challenges for your care and maintenance. A Ficus bonsai tree can be sensitive to changes in temperature, light, and humidity, and may drop its leaves if it is exposed to cold, draft, or dry air. A Ficus bonsai tree can also be prone to pests and diseases, such as spider mites, scale insects, mealybugs, and fungal infections. A Ficus bonsai tree can also be difficult to shape and style, as it can grow quickly and unpredictably. A Ficus bonsai tree can also be messy, as it can shed its leaves, fruits, and sap.
Pests and diseases can affect the health and appearance of your Ficus bonsai tree, and should be treated as soon as possible. Pests such as spider mites, scale insects, and mealybugs can suck the sap and nutrients from your Ficus bonsai tree, and cause yellowing, curling, or dropping of leaves. Pests can be prevented by keeping your Ficus bonsai tree clean and dust-free, and by spraying it with a mild insecticidal soap or neem oil. Pests can also be removed by wiping them off with a cotton swab dipped in alcohol, or by using a soft brush or tweezers. Diseases such as fungal infections can cause spots, patches, or rotting on your Ficus bonsai tree, and can spread quickly if left untreated. Diseases can be prevented by keeping your Ficus bonsai tree in a well-ventilated and sunny location, and by avoiding overwatering or underwatering. Diseases can also be treated by cutting off the infected parts and by applying a fungicide or a diluted hydrogen peroxide solution.
Aerial roots are roots that grow from the branches or trunk of a Ficus bonsai tree, and hang down in the air. Aerial roots can give your Ficus bonsai tree a more exotic and natural look, and can also help it absorb more moisture and nutrients. Aerial roots can be grown on a Ficus bonsai tree by providing it with high humidity, warmth, and light. You can increase the humidity around your Ficus bonsai tree by misting it daily, placing it on a tray of pebbles and water, or covering it with a clear plastic bag or dome. You can also encourage aerial roots to grow by wrapping moist sphagnum moss around the branches or trunk and securing it with a string or a wire. Aerial roots can take several weeks or months to form, and then they can be left to hang freely or attached to the soil or the pot.
Choosing a Ficus bonsai tree can be a fun and rewarding experience, as you can find a Ficus bonsai tree that suits your taste and style.
