Care for Indoor Bonsai Trees

The bonsai tree is a miniature tree that originated in China and Japan. Because the bonsai is a miniature tree, it requires a good bit of care to remain looking its best. What many people do not realize is that the bonsai, like most trees, is usually grown outside. They need a cold dormancy period that is typically not found while growing indoors.


One of the most important things to consider when taking care of your bonsai is placement. Choose a sunny, south-facing windowsill that will allow your tree to get at least four to six hours of sunlight per day. If you cannot provide your bonsai with that much light each day, then you should use grow lights. These are high-intensity fluorescent lights that are used indoors to help simulate natural light for your plants.


Your bonsai is planted in a small amount of dirt and needs a good deal of nutrients to remain healthy. Use a liquid fertilizer at half strength once a month during the winter and every other month in the summer. You can find liquid fertilizer at any hardware store. Follow the dosage instructions on the bottle but dilute each application with one part water.


Use a watering can or pitcher that will gently water your bonsai tree. Check the soil often and water it frequently to keep the soil moist. Provide drainage holes in the bottom of the container so the roots do not dry out. If your tree gets a lot of natural sunlight, you may need to water it every day.

Trimming and pinching

Trim your bonsai frequently as it grows so it will maintain the shape you are looking for. Do nto remove all of the new growth; this is needed to maintain the health of the plant. Different types of trees all grow at different rates. It may be necessary to pinch back often.


Repot your bonsai as it gets older and the trees roots are getting too small for the current container. As your tree gets older, the root system will mature and spread out. Use a larger pot to transplant the tree.
