Indoor bonsai trees are a little more demanding than other indoor plants. They grow in small pots with limited storage and nutrients. Follow these care guides for growing bonsai in an indoor environment.
Bonsai trees require 5-6 hours of regular direct sunlight. It's extremely important in early spring and summer during the growing season.
There are shade-loving bonsai species, but indoor environments have less light exposure than outdoor shade. Provide artificial lighting for indoor bonsai plants if your room has little light.
In the growing season, water your bonsai tree every 3 to 4 days or when the soil is dry, 2 inches under the soil. We prefer rainwater over tap water because the latter may contain harmful chemicals.
Similar to their full-grown counterparts, bonsai trees also require moderate temperatures that prevail in a natural environment. These temperatures range from 70°F to 85°F (20°C to 30°C).
A bonsai tree needs relatively high humidity to thrive in an indoor environment. Place your bonsai on a humidity tray carrying water and mist the foliage a few times daily.
The best indoor bonsai soil mixture consists of akadama, pumice, and lava rock. They make optimal water retention and good drainage if mixed in proper ratio.
Use a high-nitrogen fertilizer during the spring season and a balanced fertilizer during the summer season.
