Pinch back the bonsai's leaves with your thumb and forefinger in early spring to maintain the tree's shape.
Repot your bonsai every two years in the spring. Trim the roots at this time by removing up to 2/3 of the roots. Remove any plant debris from the soil--decomposition may cause fungal diseases.
Water your bonsai when the surface appears dry, soaking it using a watering can until water runs through the bottom of the container. Mist the leaves every two or three days with water.
Place your bonsai in a well-lit area that is kept at 60 degrees F. during the day.
Apply a balanced fertilizer every three weeks except in the winter. Dilute fertilizer by 1/2 to avoid root burn.
Scrape moss off the trunk or branches of the tree if necessary; use a hard-bristle toothbrush.
Apply pesticide if the bonsai becomes infected with caterpillars or red spider mites. These pests are attracted to bonsai.
