Fertilize geraniums perfectly - the best geranium fertilizers and home remedies

The Content Of The Article:

Geranium - Pelargonium pelargonium

Geraniums are among the hungry plants; These heavy feeders need quite a lot of fertilizer to develop magnificent leaves and flowers. Whether it must necessarily be a manure fertilizer or whether the best manure fertilizers are ever to be sought under the special "Geranium fertilizers", is rather doubtful. It is certain, however, that there are numerous home remedies that contain plant-nourishing ingredients and can be better used for fertilizing than to walk in the trash cans.

Which fertilizer do geraniums need?

The same as all terrestrial plants that do photosynthesis:
Essential for land plants are the core elements of organic matter; Carbon, hydrogen, oxygen, nitrogen and phosphorus, which are therefore also called core nutrients. These Kernnährelemente can usually be processed in different chemical bonding forms; Nitrogen z. B. is metabolized as nitrate, ammonium or amino acid, which is why it can be supplied via many different organic substances.
Other major nutrients that need to be available in more than tiny amounts are potassium, sulfur, calcium, and magnesium. In addition, a number of micronutrient elements are essential for land plants (absolutely necessary), but only in very small quantities: boron, chlorine, iron, copper, manganese, molybdenum, zinc; for higher plants (which include all our balcony and garden plants except mosses) also cobalt and nickel.
Today, there are more than 70 elements that are normally found in the natural environment of a land plant, but are considered to be expendable for plant nutrition. It's just not certain that science has "come to an end" in this regard - in terms of human nutrition, only protein, fat and carbohydrates were considered essential at the beginning. Today, just under 50 vitamins / vitaminoids, minerals, Trace elements, fatty acids and amino acids known that humans need vital.
Its nutrients are absorbed by the geranium via air, water and soil; What is not sufficiently represented in this intake must be supplied by humans.
Tip: Geraniums are originally from South Africa, where the soil does not contain any fundamentally different nutrients than ours, but where heat and sunshine are more abundant. A crucial factor in the successful geranium culture is therefore that the geraniums get enough sun; well-installed south-facing balconies can safely reach a microclimate that is quite close to the climate in South Africa. In specialized geranium nurseries you will get pelargonium varieties that even in partial shade develop abundance of flowers (in mass trade too, there's just not sure that's true), but this penumbra should not be the "darkest penumbra".

The best geranium fertilizers

Nutrient elements that can not be harvested from the soil, the air or the water, are supplied to these plants by man; This process is called fertilization.

Horn chips

21. Foodsatron
lowers the pH, which is good for geranium substrates.
22. Tea leaves
contain similar ingredients as coffee grounds, only in lower concentration.
23. Urine
would be a great nitrogen fertilizer for geraniums if it were not misplaced on the balcony.
24. cigarette ash
ensures abundant flowering in small quantities.

The advantage of "fertilizing with everything"

Which fertilizer in the soil generally lacks, would actually be determined only by soil analysis. Gardeners, "who are serious about fertilizing", can therefore also make such an analysis for the garden floor (when gardening / takeover, then every few years) and fertilize accordingly. In the natural garden, they also like to fertilize with all the nutrient-containing substances just presented, because the nutrients contained in the "funds of the household" usually only have to be digested by microorganisms.
Such fertilizers feed plants sustainably; the danger of over-fertilization, which lurks mainly in the readily available nitrogen compounds of the mineral fertilizer, is largely ruled out (though some home remedies, such as concentrated chicken manure, contain such a hefty amount of nitrogen that they need to be handled with caution). In terms of mineral supply, the home remedies offer even more variety, the colorful mixture of minerals contained in the various substances probably provides the plants better with micronutrients than any pre-made trace element mix.
Balcony gardeners can sometimes resort to soil analysis if they can get their substrate from the garden (garden soil is the perfect soil for balcony plants with loosening substances such as coarse sand or perlite).Balcony gardeners without (access to a) garden rely on pre-fertilized substrate, which would actually be great if the substrate packages were equipped with meaningful information on the nutrient content. But that's not always the case, and if nutrient information can be found, they do not necessarily have to be correct - here is a comprehensive test on the subject, whose statements are unfortunately not refuted by recent tests: test.de/Blumenerde-Die-Wundertueten- 1,167,574 to 2,167,574. If the nutrient content is difficult to determine anyway, you can also experiment as a balcony gardener with the home remedies listed above.
The fertilization with residues from the household is part of a "viable utopia": a household in which hardly any waste and particularly problematic substances occur, certainly no poisons. It works, and rethinking ("I do not have to throw this thing / this stuff in the trash now, because a company wants me to believe that it is garbage, but I can and can use it to my advantage") is more difficult But this rethinking is not only good for the planet, but also good for humans, because the rethinking towards self-determination means a good deal of freedom - and because all the remnants of z. B. can be used as fertilizer, which saves a lot of money.
