1. Choosing the Right Bonsai:
- Select a tree species suitable for indoor cultivation, such as Ficus, Chinese Elm, or Jade.
- Look for a young tree with a thick trunk and well-developed branches.

2. Placement and Lighting:
- Place your bonsai near a window with good indirect sunlight. Avoid direct exposure to intense sunlight, as it may scorch the leaves.
- Rotate the bonsai regularly to ensure even light distribution and balanced growth.
3. Watering:
- Water your bonsai thoroughly when the soil begins to feel slightly dry. Use a watering can or a gentle shower attachment to avoid disturbing the soil.
- Avoid overwatering, as it can lead to root rot. Ensure proper drainage by using a well-draining bonsai soil mix (discussed in the later section).
- Monitor the moisture level by gently inserting a finger into the soil. If it feels moist, wait before watering.
4. Humidity:
- Indoor environments often lack sufficient humidity. Enhance humidity levels around the bonsai by placing it on a humidity tray filled with water.
- Grouping bonsais together can create a microclimate with higher humidity.
- Mist the foliage occasionally, especially during dry seasons, but avoid misting directly before nighttime to prevent fungal issues.
5. Fertilization:
- Use a balanced, slow-release organic fertilizer specifically designed for bonsai.
- Apply fertilizer during the growing season (spring to autumn) as per the manufacturer’s instructions.
- Reduce or halt fertilization during winter when the bonsai is in a dormant phase.
6. Pruning and Wiring:
- Regularly prune your bonsai to maintain its desired shape and promote branching.
- Use clean and sharp bonsai pruning shears to make precise cuts. Disinfect the tools before and after use to prevent disease transmission.
- Wiring can be done to guide branches into desired positions. Use bonsai wire wrapped gently around branches, being careful not to damage them.
7. Soil and Repotting:
- Bonsai trees require well-draining soil to prevent root rot. A commonly used bonsai soil mix includes akadama, pumice, and lava rock in appropriate ratios.
- Repot your bonsai every two to three years or when the root system becomes crowded. Spring is generally the best time for repotting.
- Trim and prune the roots during repotting to maintain a compact root system. Use sharp bonsai shears for root pruning.
8. Pest and Disease Control:
- Inspect your bonsai regularly for signs of pests like aphids, mites, or scale insects. Treat them with an appropriate insecticide, following the instructions.
- Maintain good hygiene by removing fallen leaves and debris from the pot to prevent the growth of mold or fungi.
- If you notice any signs of diseases like leaf spot or root rot, consult a bonsai specialist for proper diagnosis and treatment.
