Also, make sure you take them for outdoor trips in their growing season. Furthermore, these types of trees can also be grown in low light conditions with plant lights but it is better to give them sunlight. Keep them on a windowsill that is south-faced. In summers, avoid leaving them in the hot sun during afternoons.

5. Watering Ficus Green Island Bonsai

Being a beginner-friendly bonsai, it can tolerate both over-watering and under-watering for a while. But giving them proper care which involves watering the bonsai ficus green island before the soil completely dries up. 

Watering should be done once in 2-10 days. The frequency of watering depends on the weather conditions. The best rule for watering is to dip your finger into the soil at 1-inch depth and then check the moisture of the soil. If it is wet then do not water it, and if it is a little dry, then water it. Watering your bonsai with cold water may lead to thermal shock to your plant. Collect the tap water in a container and let it adjust to room temperature, before watering. Furthermore, water your bonsai ficus green island till the water expels out of the drainage holes.

6. Misting Ficus Green Island Bonsai

Mist your ficus green island bonsai daily, as it loves being misted. In summers you can mist them twice, depending on the climate. Never leave your bonsai in dry surroundings. 

Also, misting it makes the foliage look fresh and green. Avoid misting them very often, as it may lead to the growth of mold on the foliage. Make sure that the leaves dry before misting.

7. Soil Mix For Ficus Green Island Bonsai

It is okay to use normal household soil mix for planting your green island ficus bonsai tree. Make sure the pot is well-draining. As this tree is a low-care bonsai, it does not need special soil mixtures to grow healthy. 

Also, it grows well in any conditions if you care for it properly. It is better to add organic matter to the soil mix as it boosts growth. Always use a well-drained soil mix and fertilize it regularly, to maintain the healthy growth of your bonsai.

8. Fertilizing Ficus Green Island Bonsai

Generally, bonsai are planted in small containers or pots. The soil loses its nutrients when the bonsai grows well and for a longer period. The soil will need extra nutrients to support bonsai growth. 

Often repotting is not a good idea. So, you can fertilize the soil to improve the nutrients. Fertilizing plays a crucial role in caring for your bonsai. You can use either a chemical or organic fertilizer to fertilize your plant. Regular feeding makes your ficus green island bonsai grow fast and healthy. 

If you worry about how often your bonsai should be fertilized, then it depends on the type of fertilizer you are using and the environment you are living in. If you use a liquid fertilizer, then dilute it with water in a 1:1 ratio and apply it every 2 weeks in the growing season which is in summer. In the winter season, fertilize your bonsai every 4-6 weeks. If you use slow-release pellet fertilizer, then use it once a month during summer and once in 2 months during winter.

9. Pruning Ficus Green Island Bonsai

Bonsai trees should be pruned often to maintain their height and strengthen their trunk. Pruning also helps in the growth of the bonsai. Your ficus green island bonsai can be pruned throughout the year. But, the best time for pruning your ficus green island bonsai is the end of spring and the beginning of summer. During this period, your bonsai produces a white sap that helps to recover from the cuts and avoids fungal growth in those affected areas. 

Prune out the extra leaves and stems that grow rapidly and disturbs the shape of your bonsai. If you are going to prune the foliage, then cut ½  of the new growth. 

Wiring is not recommended in the case of ficus microcarpa, as it grows rapidly and wiring may cause damage to the growing trunk. If you still want to wire your bonsai to get the desired shape, then wind the wire loosely. Also, make sure that you use only sharp pruning equipment and avoid crushing the stems during pruning.

10. Temperature And Humidity

Ficus green island bonsai tends to be in warm humid conditions and so, it is better to keep your plant indoors. As it is a tropical plant it can survive in high temperatures. But, they need to be misted and watered thoroughly. This tree loves to stay in humid conditions. You can use a humidity tray to maintain the humidity levels. If you cannot maintain the humidity tray, then keep misting it daily and increase the frequency in dry conditions. 

Humidity helps in the aerial root growth that makes your bonsai look super-cool. The suitable temperature for a ficus green island bonsai is 59-86 degrees Fahrenheit. Do not leave your bonsai outdoors at night in the cool winter. Leaving your bonsai in temperatures below 45-59 degrees Fahrenheit may lead to its death.

11. Potting And Repotting

Use a shallow and wide pot to plant your bonsai. Shallow pots allow the bonsai to show its aerial root growth. Fill the pot with the suitable soil mix and plant your ficus green island. 

If you are planning to repot, I will advise you to fertilize, water, and prune your bonsai from time to time to improve the growth of your bonsai. Repot your bonsai green island ficus after every 2-5 years depending on the condition of your bonsai.

12. Pests And Diseases

Like all other plants and bonsai, green island ficus also suffers from some pests and diseases.

  • Over-watering your bonsai will lead to root rot and the growth of mold on different parts of the plant. Even under-watering will bother your plant by falling foliage and discoloration.
  • Mealy bugs: This is the process of growing cotton-like insects that form groups on the stems and branches. They can be observed after watering. These insects can also cause discoloration of leaves. Spray neem oil on the insects to avoid them. You can also use chemical insecticides or soap to get rid of them. 
  • Centipedes: Centipedes affect the roots of your bonsai. It is better to repot and use sterile soil mix to fill the well-cleaned or sanitized pot, to avoid them. These insects are usually brown with a lot of legs.
  • Scale: A disease where small bulbs which are in black or white color grow on the stems of your bonsai. These can be avoided by spraying pesticides.
  • Anthracnose: It is a disease that affects the leaves of your bonsai. Leaves start to discolor in the edges and then the whole leaf will become yellow. After some days, the leaves will become brown and finally fall off. It is due to the fungal growth in the plant. So, use fungicides to avoid them.
