Prof. Martin Thorne, Ph.D.The placement of your bonsai indoors determines whether it will survive and thrive. A south-facing window will give almost all species plenty of sunlight. Avoid drafty areas near doors or heat sources, such as radiators. The correct placement creates microclimates that are closer to their natural habitat. In fact, I saved my ficus, which was suffering near an AC vent, by moving it elsewhere.
Light Requirements
- Tropical species: 4+ hours bright indirect light
- Subtropical varieties: Direct morning sunlight
- Use reflective surfaces to boost light exposure
- Monitor for leaf scorch in intense summer sun
Humidity Solutions
- Pebble trays with water beneath pots
- Group plants to create moisture pockets
- Avoid misting which promotes fungal growth
- Use room humidifiers during winter months
Year-round health is managed by seasonal adjustments. In winter, move trees away from cold windows to prevent damage. Raise humidity during heating season. You may need curtains in the summer to diffuse the light. I use digital thermometers to observe the stability of the microclimate around my bonsai collection.
To enhance sunlight, you can use artificial lighting to provide supplemental light to trees during cloudy days and in winter months. Full-spectrum LEDs work more effectively positioned 6-12 inches above plant canopies. Set timers for full 12-hour daily cycles. You can adjust grow lighting intensity depending on a species' needs. My tropical bonsai grows great under lights during the cloudy winter months.
Steer clear of common placement mistakes. Avoid placing trees near ethylene-producing fruit bowls. Keep trees away from kitchen fumes and cleaning product vapors. Ensure there is air movement, but no forced drafts. If you follow these guidelines, you can limit the effects of stress that cause trees to decline.
