How to Take Care of a Bonsai Tree – Quick tips
- Water only when the topsoil feels dry—not daily by default
- Make sure your Bonsai gets proper light (natural or grow lights)
- Use well-draining soil, not regular garden mud
- Keep humidity in check, especially indoors
- Feed with balanced fertilizer during growing months
- Trim new growth regularly to keep the shape
- Watch out for signs of pests or stress
Watering Bonsai Tree – Not Too Much, Not Too Little
Watering is probably the trickiest part of Bonsai care, but once you get a feel for it, it becomes second nature.
- Check the top layer of soil—if it feels dry, it’s time to water
- Use a watering can with a soft spout so you don’t disturb the roots
- Always make sure excess water drains out—no standing water!
- In summer, you may need to check moisture levels daily
- Every Bonsai species is different, so observe how yours reacts
Bonsais don’t like being too wet or too dry—it’s about balance.
Soil for Bonsai Tree – The Right Foundation
The right soil makes a world of difference in how your Bonsai grows.
- Choose well-draining Bonsai mix, not regular potting soil
- Good mix: akadama + pumice + lava rock (or buy ready-made)
- Add perlite or coarse sand for extra drainage
- Repot every couple of years to refresh the soil and trim roots
- Never let the roots sit soggy—Bonsai roots need to breathe
Sunlight for Bonsai Tree – Bright, But Not Harsh
Sunlight is food for your Bonsai. Give it the light it needs, and it’ll reward you with beautiful growth.
- Outdoor Bonsais: Need 4–6 hours of direct sunlight
- Indoor Bonsais: Place near a bright window (south or east-facing is best)
- Rotate the pot every few days so all sides get even light
- In extreme summer heat, give some afternoon shade
- If light is low, try using a grow light to support it
Light-starved Bonsais tend to grow weak and drop leaves—avoid that!
Humidity and Temperature – Create the Right Environment
Indoor air can get quite dry, especially with fans or AC running—and your Bonsai will feel it.
- Keep humidity moderate to high
- Mist the leaves lightly in the morning during hot or dry days
- Use a humidity tray filled with pebbles and water under the pot
- Best temperature range: 15°C to 30°C
- Avoid placing your Bonsai near heat vents or cold drafts
A little extra care with humidity goes a long way in Bonsai health.
Fertilizer for Bonsai Tree – Feed It the Right Way
Because Bonsais grow in small pots, they need regular feeding to stay strong.
- Use a balanced liquid fertilizer (like NPK 10-10-10)
- During spring and summer: feed every 2 weeks
- In winter: once a month or stop if your Bonsai is dormant
- Water before you fertilize—never feed dry soil
- Organic slow-release fertilizers are great too
A well-fed Bonsai grows healthier leaves, stronger branches, and better roots.
Propagate Bonsai Tree – Growing Your Own Mini Forest
Want more Bonsais? Good news—propagating them is easier than you think.
- Stem cuttings: Most common method; take from healthy branches
- Use rooting hormone for quicker root development
- Keep in moist soil and place in indirect light
- Air layering works great for woody types like maple or fig
- Growing from seeds is possible but takes time and patience
It’s rewarding to see new Bonsai life sprout from your own hands.

| Falling leaves | Sudden temperature changes | Keep temperature stable, avoid AC blasts |

Yellow leaves usually mean overwatering or lack of sunlight. Check the soil moisture and light conditions. Adjust your watering and move the plant to a brighter spot if needed.
