How to Grow Bonsai Faster (Proven Techniques That Actually Work)
Introduction
One of the most common questions in bonsai is:
“How can I make my bonsai grow faster?”
The truth is, bonsai doesn’t have to be slow.
With the right techniques, you can dramatically speed up growth, thicken trunks faster, and develop your trees in a fraction of the time.
In this guide, you’ll learn the proven methods used by experienced growers to accelerate bonsai development.
Understanding Growth vs Refinement
Before trying to grow your bonsai faster, it’s important to understand one key concept:
👉 Development vs Refinement
- Development phase = growing the tree quickly (thickening trunk, building structure)
- Refinement phase = slowing growth to improve detail and ramification
If your goal is faster growth, you need to focus on development techniques, not refinement. Check out our Development vs Refinement Downloadable Class.
1. Use Larger Pots (Or Grow in the Ground)
One of the fastest ways to increase growth is to give your tree more space.
- Larger pots = more root growth
- More roots = faster top growth
For maximum speed:
- Grow in larger training pots ( Black Plastic )
- Or plant directly in the ground (if possible)
👉 Small bonsai pots restrict growth — which is great for refinement, but not for development.
2. Let Sacrifice Branches Grow
This is one of the most powerful techniques in bonsai.
A sacrifice branch is a branch that is allowed to grow freely to:
- Thicken the trunk
- Increase overall vigour
These branches are removed later once their job is done.
👉 This is how you build thick, aged-looking trunks much faster.
3. Feed Your Bonsai Properly
Fertilising is essential if you want fast growth.
- Use a balanced fertiliser
- Feed consistently during the growing season
- Increase feeding during development
Stronger feeding = stronger growth (when done correctly)
👉 Many beginners underfeed their trees, which slows development significantly.
4. Maximise Sunlight
Light = energy.
The more direct sun light your tree receives, the more energy it has to grow.
- Most bonsai thrive in full sun
- More sun = faster growth and stronger health
👉 Trees kept in low light will always grow slowly, no matter what you do.
5. Water Correctly and Consistently
Water plays a huge role in growth.
- Never let your tree dry out completely
- Water thoroughly when needed
- Maintain consistent moisture levels
Healthy roots = faster growth.
6. Use the Right Soil
Bonsai soil should:
- Drain well
- Hold sufficient moisture
- Allow oxygen to reach roots
- Support strong root development
- Retain nutrients
Poor soil slows growth and can damage roots.
👉 Good soil = better root health = faster development.
7. Avoid Over-Pruning During Development
If your goal is faster growth:
👉 Do not over-prune
- Pruning reduces energy
- Less foliage = less photosynthesis
- Less photosynthesis = slower growth
During development, allow the tree to grow more freely, Only prune if there is going to be flaws grown into the tree that cant be fixed such as swelling at significant junctions.
8. Choose Fast-Growing Species
Some species naturally grow faster than others.
Good options include:
- Ficus varieties
- Chinese Elm
- Bald Cypress
These species respond well to feeding and development techniques.

Common Mistakes That Slow Bonsai Growth
Avoid these if you want faster results:
- Keeping trees in small pots too early
- Not feeding enough
- Growing indoors with low light
- Over-pruning
- Poor soil choices
Fixing these alone can dramatically increase growth speed.

Final Thoughts
Bonsai doesn’t have to take decades to develop.
By focusing on:
- Strong feeding
- Proper sunlight
- Root development
- Strategic pruning
