Prof. Martin Thorne, Ph.D.The essential aspects of bonsai care pertain to requirements specific to the tree species. Tropical species, such as Ficus, have very different needs from those of temperate climate species, like Juniper. Knowing the natural environment and habitat of your tree will help you provide the correct light and humidity for the tree to thrive. Supplying these parameters will reduce stress to the tree and support healthy growing patterns throughout the year.
Light Management
- Tropical species: 4+ hours bright indirect light
- Temperate species: Seasonal outdoor sunlight exposure
- Use full-spectrum LEDs in low-light environments
- Rotate trees weekly for even development
Watering Protocol
- Check soil moisture 1 inch deep before watering
- Adjust frequency with temperature changes
- Use immersion method for thorough saturation
- Morning watering prevents overnight moisture issues
Preserve enhanced health and balanced growth with systematic pruning. The planned goal is to prune up to 20-30% of foliage each month. Each month, prune your trees according to their root structures and canopy. I learned that these balanced procedures reduce tree shock. Take precautions to protect your trees from environmental stressors such as drafts that fall below 50 degrees or direct heat vents.
Protection approaches help maintain longevity. Locate trees away from drafty windows and heating elements. Consider partial microclimates using humidity trays in dry months. Seasonal placement changes can help alleviate temperature stress. I found my juniper did better once I moved it from the AC vent.
Consistently implement these guidelines. Monitor your trees daily for signs of stress as soon as possible. Regardless of what you notice, omitted from your usual tree boarding and care before the issue becomes problematic, always note the changes made in a care notebook. Proactive care will help your trees remain healthy throughout seasonal transitions and their growth periods.
