- Tropical tree variants
- Sub-tropical variants
The good news is with proper care, these species and variants of the bonsai tree will flourish happily inside any room.
The top five choices for worldwide indoor bonsais are as following:
The ficus species are available in 850 variants and are the most popular bonsai species for indoor growth. Most people choose ficus bonsai due to its milky sap, which is produced by cuts on three. Some species may even bloom, but it is pretty rare.
Ficus is highly adaptive for different conditions and needs low light and humidity. So, beginners may find it an excellent option to kick off their bonsai career.
Chinese elm is famous as an indoor bonsai tree. But its positivity doesn’t end here. Thanks to its easy caring, Chinese elm is a great option for beginners.
The growth rate is pretty fast and predictable, making pruning, trimming, and wiring the tree to form a particular shape easy and hassle-free. Also, the tree is tolerant to overwatering, low light, and humidity that makes it a top choice for indoor bonsai.
Thanks to its attractive, engaging, and abundant flowers, snow rose has been the favorite of many bonsai planters. The stem is woody and can be an excellent option for both indoor and outdoor bonsai.
It is known as the tree of thousand stars for its small and attractive flowers. In fact, it will bloom continuously in almost all seasons. But most flowers will bloom during the early spring.
However, we don’t recommend snow rose for beginners, as it is a high-maintenance bonsai tree. If the temperature and humidity fluctuate, the tree will become stressed easily.
The Carmona bonsai is also known as Fukien Tea. It blooms almost year-round, and its small whitish flowers truly look attractive and captivating.
Also, Carmona bonsai is found widely in roadside bonsai vendors, as the tree can thrive both indoors and outdoors with relative ease. Its foliage is small, and the upright style is truly amazing. Plus, it thrives easily in strong to medium sunlight, which makes its maintenance easy and quick.

Can I Keep Temperate Bonsai Indoor?
Temperate bonsai species are dependent on their dormancy period during the wintertime. The dormancy period refers to when the tree reaches its yearly growth cycle and prepares itself for the new life cycle.
The dormancy period is directly dependent on the intensity of the light and temperature. It starts with the decreasing light and temperature in the environment. When the temperate bonsais are kept inside, it can’t detect the increase or decrease in the temperature and light.
Thus, you can’t grow temperate and non-tropical bonsai trees indoor.
Caring and Maintenance Tips for Indoor Bonsai Trees
Indoor bonsai plants need special care as they aren’t exposed to direct sunlight and temperature. Also, their caring is different from the common outdoor bonsai species. On top of it, when grown in small pots, these bonsai species need proper fertilization to get the necessary nutrients which they would receive from the soil.
Also, you need to replicate the tropical humidity and temperature for these trees to strive and grow just the way you want.
Ensure proper light:
At indoor, the light intensity is relatively low compared to the outdoor locations. When the tree is exposed to such conditions for an extended period, it will slow down its growth rate. Thus, ensuring proper light for indoor bonsai is the main challenge.
Ideally, you should place the bonsai close to direct sunlight near a window. In this regard, south-facing window placement for the bonsai will be a great help.
Also, arrange artificial lighting to increase the lighting intensity for proper growth and healthiness of the indoor plant. Expert gardeners will use fluorescent lights to supplement the light deficit for these indoor bonsai plants.
Humidity is the key:
Indoor bonsais are mainly tropical tree species that need high humidity for survival. Thus, you have to maintain a high humid condition for these trees inside the house.
But this can be challenging since our home has heating machines and air conditioning installed to soak up excessive humidity. But there’s an easy solution to this problem. You should use a humidity tray and place the bonsai pot on it with water-filled in the tray.
Also, mist the tree following the expert’s recommendation to maintain a high humidity level. Finally, open the nearby window to allow humid air to come inside and moist the tree.
Don’t forget watering and fertilization:
Although the label on your bonsai plant will suggest you water the plant on a routine, it is not appreciable. Instead, you should regularly check the soil’s dampness and water it as per the best indoor bonsai maintenance requirements.
You may use a moisture meter to calculate the dampness or apply the conventional chopstick or finger method for measuring the dampness. When the soil feels a bit dry, you should water it.
Next, you have to fertilize the soil during the growing season of the bonsai trees. It lasts from early spring to the mid-fall season. Also, choose a fertilizer with the proper balance of potassium, phosphorus, and nitrogen. Ideally, a 10 10 10 fertilizer is recommended for bonsai plants.
Furthermore, make sure that bonsai fertilizer also includes the essential micro-nutrients such as zinc, iron, boron, manganese, etc., in proper ratio to ensure the health and growth of the plants.
Maintain the right temperature:
Tropical species need high temperatures for proper growth. The good thing is in most locations, the indoor temperature is quite ideal for these plants to thrive with relative ease. But things can be a little different if you are from a cold region, where the temperature often goes below sub-zero level.
It would be best to place the plants near a window or door to avoid the effects of temperature drop. Plus, high-intensity fluorescent light can be a good alternative to providing warmth for the indoor bonsai.
Repotting and pruning:
Most indoor bonsai plants would require repotting every other year. It is crucial since the older soil will not have enough fertilizer to maintain the tree’s growth. Plus, smaller pots will outgrow the older bonsai plants.
Hence, you have to apply repotting technique for the proper growth of these species. Plus, you must prune, trim and wire the plants to achieve your desired shape, which is the ultimate goal for indoor bonsai arrangements.
