How to Care for Indoor Bonsai Tree in Low Light: Seek the Light, Young Tree
Most indoor bonsai fail because they don’t get enough light. Remember: your tree was born under the sun!
Natural Light Tips:
- Place your bonsai near a south-facing window if you’re in the Northern Hemisphere (north-facing in the Southern Hemisphere).
- Rotate the tree every few days to ensure balanced growth.
- Avoid cold drafts and direct heater exposure.
Grow Lights: The Indoor Sun
If natural light isn’t enough, a full-spectrum LED grow light will do wonders. Master Mori uses one shaped like a lotus flower—though any efficient model will do.
Recommended Products:
Set your light on a timer: 12-14 hours per day is ideal for bonsai.
Humidity: The Invisible Rain
Indoor air—especially with heaters or AC—is dry. Indoor Bonsai trees need humidity to stay healthy. Master Mori once kept his Serissa in the bathroom just to enjoy the steam!
Tips to Boost Humidity:
Humidity trays: Fill a shallow tray with pebbles and water. Set the bonsai pot above the water line.
Mist daily, especially in dry climates.
Group multiple bonsai together to create a microclimate.
Use a room humidifier if you have multiple indoor plants.
Watering Indoor Bonsai Trees vs Outdoors
Indoor bonsai don’t dry out as quickly as their outdoor cousins, but this doesn’t mean you can slack off!
Master Mori’s Watering Wisdom:
Stick your finger into the soil—if the top 1-2cm is dry, water it.
Use a gentle watering can or squeeze bottle.
Let water drain thoroughly from the bottom—never let roots sit in water.
Reduce watering frequency during colder months.
Overwatering is a slow death. Underwatering is a fast one. Find the path between
How to Care for Indoor Bonsai: The Right Soil Mix
Not all dirt is created equal. Regular potting soil holds too much water. You need a fast-draining bonsai soil mix.
Recommended Indoor Mix:
1 part akadama
1 part pumice
1 part lava rock or fine orchid bark
You can also buy pre-mixed soil designed for tropical or indoor bonsai.
Common Indoor Bonsai Problems & Fixes
Yellow Leaves – Often due to overwatering or lack of light.
Leggy Growth – Insufficient light; consider a grow light.
Pests (spider mites, aphids) – Spray with neem oil or insecticidal soap.
Root Rot – Poor drainage or too much water. Repot and prune roots.
Leaf Drop – Normal with species like Ficus when moved. Monitor light and water.
If Master Mori had a scroll for every pest he banished… well, he’d need a bigger hut.

How to Care for Indoor Bonsai FAQ
Q: How do you keep a bonsai tree alive indoors?
Treat it less like décor and more like a demanding roommate. Place it near a bright window (they love light), avoid dry air (hello, humidity trays), and don’t let it bake on top of a heater or freeze in front of an A/C. Oh, and talk to it if you like—Master Mori swears by daily tree talk.
Q. How often should you water an indoor bonsai tree?
A. Ah, the ancient mystery! There’s no set schedule—water when the topsoil feels slightly dry, not when your calendar says so. In summer, that might mean daily. In winter, maybe every 3–5 days. Stick your finger in the soil up to the first knuckle. If it’s dry, it’s time for a drink. If it’s wet, let it be. Overwatering is the silent bonsai killer.
Q: Can any bonsai be grown indoors?
No. Only tropical and subtropical species like Ficus, Serissa, and Jade thrive indoors.
Q: How often should I repot my indoor bonsai?
A: Every 2–3 years, depending on growth and root health.
Q: Why is my bonsai dropping leaves after moving it indoors?
A: Trees like Ficus often drop leaves when adjusting to a new environment. Give it time and steady care.
Q: Can I keep bonsai in my office with fluorescent lighting?
A: Only if you supplement with a full-spectrum grow light.
Q: Should I fertilize in winter?
A: Reduce or pause fertilizing during dormancy or slow growth periods.
