Part 1 - FEEDING THE PLANTS, AND THE SOIL!
Fertilization is crucial for the survival of Bonsai, which, being trees, have high nutritional requirements and, because they live in a limited space, have a reduced capacity to retain nutrients.
The success of cultivation lies in the use of the maxim: "a little at a time, often...", and high-quality fertilizers with balanced formulas that, when combined, ensure they enhance each other without canceling each other out, and that leave no residues in the substrate, which would eventually become harmful to the plant (see at the end of the text "Leipzig Law - Law of the Minimum").
The huge diversity of species we cultivate, with different nutritional requirements, leads the most specialized (or curious) Bonsai enthusiasts to seek different products with complementary objectives.
You don’t have to use the entire range to maintain one (or more) Bonsai, but when you decide to increase the number of products you use, you should follow a "Nutritional Protocol" to optimize them and avoid mixtures that cancel each other out.
In the 2 demonstration tables of how to use our range, the application days are merely exemplary, we must always respect the plant's watering needs and the weather conditions (if it rains a lot or is very hot, it is not ideal); we apply the products on a day when the plant needs watering, ensuring 2 days interval between applications (except for products we suggest combining).
-"Basic Nutrition Plan," simple and sufficient for healthy Bonsai maintenance (in green on the table), composed of:
A complete fertilizer that can be (1) Fertil Bonsai Humic or (2) Green & Gold Bonsai Organic or (3) Biogold, complemented with a Bio-stimulant (4) Bio Bonsai Activ.

-"Nutritional Reinforcements" (cream color on the table) prevent deficiencies (it is always easier to prevent than to fight, especially if we have many plants), and provide specific stimuli (+flower, +fruit, +resistance), they complement the "Basic Nutrition Plan", (5) Micro Bonsai Complex and/or (6) Iron Bonsai Complex.
Both products can be used separately or applied together with the (4) Bio Bonsai Activ and with (1) Fertil Bonsai Humic.
*When choosing to apply the above products together, we should place 1 recommended dose of each product in one liter of water (or proportionally), resulting in a single liter of water containing 2 individual doses of product.
The application of (7) P/K Bonsai Algae is strongly recommended for outdoor plants to prepare them for Winter (it can also be used indoors) and especially for flowering and fruit plants to stimulate these processes.
Part 2 - PREVENTION IS THE BEST SOLUTION!
- "Root Growth Promoting Microorganisms (PGPR)" (pink in the Table):
The combination of (8) Rhiza Bonsai Plus with (9) Probiotic Bonsai Plus, increases the plant's nutrient uptake and availability, as well as creating a "suppressive soil" (soils in which beneficial microorganisms outnumber harmful ones, neutralizing them by competition).
- "Systemic Resistance Inducers (ISR)" (pink and blue in the table):
Regular rotation of "PGPR" with ISR phytoprotectors "ISR" (9) Probiotic Bonsai Plus, (10) Resist Bonsai Synergic, (11) Defense Bonsai Synergic and (12) Protect Bonsai Synergic, ensures plant defense against many abiotic stresses (environmental stress such as drought, excess water, frost, etc.) and biotic stress (fungi, bacteria, and harmful pests).
Part 3 - SOMETIMES LESS IS MORE....
"Common sense" has led the Bonsai world to believe that using fertilizers with high nutrient levels (especially N-P-K) would ALWAYS accelerate growth and results more.
The principle of using only excessively draining soils (exclusively mineral origin), so plants dry quickly and we can water more often with more fertilizer... doesn't make sense in light of current agricultural science. These soils, without any organic matter, also do not retain most nutrients, nor do they create the bacterial life essential for nutrient assimilation and plant resilience.
Often, the result is precisely the opposite; for example, the abusive use of nitrogen (N)-based fertilizers leads to tender vegetative growth that encourages the appearance of fungi and pests, and increases internode spacing and leaf size, causing aesthetic disproportions in the Bonsai.
Plants assimilate nutrients in a combined manner, so excess nutrients sometimes "neutralize" others by competition/antagonism, salinize and degrade the soil, destroying its Cation Exchange Capacity (CEC).
- Liebig’s Law or Law of the Minimum - Published by "Justus Von Liebig" in 1840 and immortalized by the famous "Liebig’s Barrel", it defended what science now confirms: plant development is controlled/limited by the element* or nutrient in shortest supply; all others cannot be assimilated and end up being wasted.
* element - for the plant to develop, besides nutrients, other elements such as water, sun, air, etc. are necessary... if these are not properly provided, no product/fertilizer works miracles...
Nutrient needs vary throughout the plant's vegetative phase and also by species, soil type, etc.; in Bonsai, we use hundreds of species, hence the importance of a balanced "Nutritional Protocol".
All our products are developed specifically for Bonsai production, used daily in our greenhouses on thousands of plants, and finally created and tested in modern independent laboratories.

In the example of this barrel, without increasing Magnesium (Mg), the plant would not grow more, even if we increased the other nutrients; we might even be using some that block it, further limiting growth....
