A Beginner’s Guide: How to Care for Bonsai Trees Indoors.

Mar 5, 2024

Bonsai trees are a beautiful and elegant addition to any indoor space, bringing a touch of nature and tranquility into your home. These miniature trees require special care to thrive indoors, but with a little knowledge and attention, you can enjoy the beauty of bonsai for years to come.

In this guide, we’ll explore the essentials of caring for bonsai trees indoors, along with five important questions related to bonsai tree care.

Choosing the Right Location for Bonsai Tree:

  • The first step in caring for your indoor bonsai is selecting the perfect spot for it to thrive. Bonsai trees require plenty of indirect sunlight, so place them near a bright window where they can receive ample light throughout the day. Avoid placing them in direct sunlight for extended periods, as this can cause the leaves to burn.


  • Proper watering is crucial for the health of your bonsai tree. Check the soil regularly and water your bonsai when the top layer feels dry to the touch. Be sure to water thoroughly, allowing the water to soak through the entire root system. However, avoid overwatering, as this can lead to root rot and other problems. A good rule of thumb is to water your bonsai when the soil feels slightly damp, but not soggy.

Pruning and Trimming:

  • Regular pruning and trimming are essential for maintaining the shape and health of your bonsai tree. Remove any dead or yellowing leaves, as well as any branches that are growing too close together or in the wrong direction. Pruning should be done with sharp, clean scissors or shears to prevent damage to the tree.


  • Bonsai trees require regular fertilization to replenish the nutrients in their soil and promote healthy growth. Use a balanced, water-soluble fertilizer specifically designed for bonsai trees, and apply it according to the manufacturer’s instructions. Fertilize your bonsai during the growing season, typically from spring to early fall, and reduce or eliminate fertilization during the dormant winter months.


  • As bonsai trees grow, they will eventually outgrow their containers and require repotting. Repotting should be done every two to three years, or whenever the roots become crowded and pot-bound. Use a well-draining bonsai soil mix and carefully remove the tree from its old pot, trimming any circling roots before placing it in its new container. Repotting is best done in early spring before the tree enters its active growing season.

Now, let’s address five common questions related to bonsai tree care:

How often should I water my bonsai tree?

  • The watering frequency will depend on factors such as the size of your bonsai tree, the type of soil it’s planted in, and the climate in your area. As a general guideline, check the soil regularly and water when the top layer feels dry to the touch.

Why are the leaves on my bonsai turning yellow?

  • Yellowing leaves can be a sign of various issues, including overwatering, underwatering, nutrient deficiencies, or pest infestations. Assess the condition of your bonsai tree and make any necessary adjustments to its care routine.

When should I prune my bonsai tree?

  • Pruning can be done throughout the year as needed to maintain the shape and health of your bonsai tree. However, avoid heavy pruning during the dormant winter months, as this can stress the tree.

How do I know when it’s time to repot my bonsai tree?

  • Signs that your bonsai tree may need repotting include crowded or circling roots, slow growth, and poor drainage. Check the roots periodically by gently removing the tree from its pot and inspecting the root ball.

Can I keep my bonsai tree indoors year-round?

  • While bonsai trees can be kept indoors, they will benefit from spending time outdoors during the warmer months to receive ample sunlight and fresh air. Just be sure to gradually acclimate your bonsai to outdoor conditions to prevent shock.
