Bonsai need optimal care in order to flourish magnificently. This includes above all the right fertilizer. Without it, the bonsai would lack important nutrients.Anyone who acquires a bonsai tree should already be aware that these plants need a lot of care and attention. But with a little water and a regular pruning, it is far from over.
Bonsai need fertilizer as an additional food. The trick is to choose the right fertilizer in the optimal composition. The combination of water, light and fertilizer ensures optimal growth of the miniature trees.
Which fertilizer is best for bonsai trees?
There are special fertilizers for bonsai which, apart from a high price, offer no significant benefits. A normal whole fertilizer, such as The green plant fertilizer from Compo offers everything the bonsai needs.
The fertilizer consists of the three main nutrients nitrogen, phosphorus and potassium. In addition, the fertilizer may contain other ingredients, for example magnesium, iron, zinc, copper and manganese. The label on the package or bottle contains the three letters N (nitrogen), P (phosphorus) and K (potassium oxide), the numbers behind indicate the percentage of each nutrient. A balanced relationship is important for the individual components to be effective.
The individual components serve this purpose:
For green and strong leaves, the bonsai needs nitrogen. The element nitrogen is mainly found in the atmosphere and is generally the engine for healthy growth. As a plant food, nitrogen is important for the formation of the green leaf mass. You recognize a lack of a pale leaf color and a meager growth.
Phosphorus is needed for flower and fruit formation. The roots absorb phosphate - the salt of phosphoric acid - from the soil. In the case of a phosphorus deficiency the growth suffers, the flowers are diminished.
Potassium is mainly responsible for building up the wood pulp. In case of a potassium deficiency you notice weak branches and soft petioles on your bonsai. In addition, bonsai are then often prone to disease.
When and how often should the bonsai be fertilized?
Water-soluble fertilizer is absorbed quickly by the roots of the plant and supplies the bonsai with important nutrients.
»Beware of the dosage: With mineral liquid fertilizer, you can easily over-fertilize. Follow the instructions on the pack or bottle and keep an eye on the bonsai. Better not enough than too much! With solid fertilizer the over-fertilization does not happen so fast, here however the smell can have a disturbing effect.
The growth phase of bonsai is, as with all trees, from spring to late summer. During this time, regular fertilizer inputs make sense. Gradually dimmer gradually from spring to autumn.
Important exception when fertilizing the bonsai!
Mineral fertilizer is suitable for all bonsai that have a high content of organic matter in the soil mixture, for bonsai that you keep in the room, as well as for outdoor bonsai. However, if you use a special bonsai soil, such as Akadama, Kanuma, Kiryu, or a mixture of them, you will need to take an organic fertilizer. Bonsai soil consists of clay granules, a mineral fertilizer is out of place here.
