Premium Japanese quality
Made in Japan from selected natural raw materials using a fermentation method with decades of professional use.
Steady, controlled feeding
The pellets release nutrients gradually through watering and, as a top dressing, work for about two months depending on conditions.
Clean, practical use
They are easy to distribute over the surface, and the initial organic odour becomes almost imperceptible after the first watering.
For every stage of your collection
The amount can be adjusted to the tree's size, vigour and stage of development — this control is one of Biogold Original's main advantages.
Regular feeding during growth
For a steady nutrient supply while the bonsai is actively growing.
Small or sensitive trees
Begin with fewer pellets and increase only when the plant is responding well.
Larger or vigorous bonsai
Adjust the amount gradually to the tree's size, vigour and actual requirements.
When you prefer liquid feeding
The pellets can be extracted in water for root application, especially where watering is less frequent.
A clear dose without guesswork
For a bonsai in a pot of about 15 cm, the indicative dose is approximately 15 pellets. For first use or a new environment, begin with a smaller amount and adjust according to the tree's response.
- 15 cm bonsai: ~15 pellets
- Surface application
- Works for about 2 months
- Liquid: 2–3 pellets/L
- Start conservatively
Use approximately 15 pellets as an indicative starting amount.
Distribute the pellets evenly over the surface around the root area, then water normally.
Add fresh pellets when the previous ones have dissolved. Duration is about two months and varies with watering, substrate and environment.
Place 2–3 pellets in 1 L of water. For fuller extraction, leave them for about 7 days and apply the clear upper part of the liquid around the root area.
Important: more is not better
For a small, weak or unfamiliar tree, begin with fewer pellets. In rare cases, excessive application can damage the roots, so always adjust the amount to the plant, substrate and watering rate.

Frequently asked questions
What to know before investing in one of the most recognised Japanese feeding choices for bonsai.
01What justifies its premium price?
It combines Japanese production, selected natural raw materials, pure-culture microbial fermentation and decades of professional use. The 900 g pack, roughly two-month solid duration and choice of solid or liquid application provide meaningful flexibility for a bonsai collection.
02How many pellets should I use for a 15 cm bonsai?
The official indicative amount for a pot of about 15 cm is approximately 15 pellets. For a small, weak or newly acclimatising tree, begin with fewer and increase only if required.
03How often should I renew the pellets?
Renew them when they have dissolved. As a top dressing they work for about two months, but actual duration changes with watering, rain, substrate and growing conditions.
04Can I use it as a liquid fertiliser?
Yes. Place 2–3 pellets in 1 L of water and, for fuller extraction, leave them for about 7 days. Apply the clear upper liquid around the root area; the indicative duration of liquid feeding is about 10 days.
05Does a white coating on the pellets mean spoilage?
Not necessarily. In humid or less ventilated conditions, the fertiliser's maturation microorganisms may become visible on the surface. This alone is not a quality problem, and the pellets may still be used normally.
06Does it smell, and how should I store it?
A mild organic odour may be present when the pack is opened, but it becomes almost imperceptible after the first watering. Always close the zipper and store the product in a cool, dry place away from sun, moisture, children and pets. As a natural organic material, it may occasionally attract small gnats.
