When I bought my bonsai (I have a privet, an elm and a Ficus ginseng) about 4 weeks ago, I also bought the liquid manure for bonsai with trace elements. But I have never fertilized yet. Behind my bottle there’ written (N:P:K =1).
Dosage: From 5 to 10 ml per liter of irrigation water; the treatment should be repeated every 15 days and then write that the cap of the package is equal to 20g and can be used as a measuring spoon in 2 liters of water.
AZOTO 4.0% of which N ureic
ANIDRIDE FOSFORICA (soluble in water):7,0%
OSSIDI DI POTASSIO (soluble in water): 7.0%
BORO (soluble in water):0,05%
RAME (soluble in water):0,01%
MANGANESE (chelated with EDTA:0,01%
ZINCO (soluble in water):0,01%
Since I have read around that it could create some problem to those who are inexperienced because it is not inorganic, to be cautious what do I do? For safety I dissolve 5 ml in a liter of water and water? Or will it be a little bit?
Thank you for your advice … Thank you in advance, I extend my warmest regards …
Response : Advice Fertilization Bonsai
Fertilizers are important for all plants, especially if they are potted plants, and especially if they are bonsai, which have a tiny pot; in nature the plants of the forest do not receive fertilizers from man, and then find the mineral salts they need from the ground; but on the one hand the root system of a tree in the forest has the possibility of widening “at will”, in search of the salts it needs; on the other hand, leaves, seeds, fruits, small dead animals, the droppings of the animals in the forest fall continuously around the trunk of a tree: In this way, the soil of the forest recovers from the environment a lot of material, which decomposes, releasing into the ground many substances that serve the trees, in a slow continuous process.
The soil conditions of the pot of a bonsai are very different from the natural ones: the roots of the bonsai absorb minerals essential for the development of the plant, until in the soil there are no more. And at this point we either change the whole soil, or we add fertilizer.
When we choose a fertilizer is always good to choose the specific one for the plants we are growing, because each plant has different needs, if possible we choose the best on the market, which contains nitrogen, phosphorus and potassium, but also trace elements such as boron, zinc or manganese, just like your fertilizer.
In particular, the fertilizer you have purchased is rich in phosphorus and potassium, a little less nitrogen; it is therefore more suitable for summer and autumn fertilizations, less for those of late winter, where a fertilizer a little richer in nitrogen should be used.
Since you are new to fertilizers, I think it is early to buy a lot of different fertilizers, one for each season, rather learn to use what you already have, and learn a little about how the fertilizers are composed, so that in the future you can choose by yourself the fertilizer you think is the most correct.
As a general rule, when we do not know a fertilizer well, it is good to provide it in small doses: in this way we will ensure a certain amount of mineral salts to the soil of our bonsai, but without risking excesses, which can burn the roots.
The explanations on the bottle of your fertilizer are quite confusing, first they give you the dose in ml, then they tell you how many grams the measuring spoon contains; however, consider that, if it were water, one gram and one milliliter occupy the same volume, so more or less 10 ml of fertilizer fill half a 20 g scoop.
I advise you to give small doses to start with, so half a measure every two liters of water (in this way you stick to the words on the bottle, which says 5-10 ml per liter of water, but staying on the lowest dose); every 15 days more or less is fine.
