Coffee grounds - a cheap fertilizer for your geraniums
Statistically speaking, every German drinks 77,000 cups of coffee during his lifetime, which equates to a daily consumption of 0.41 liters - with these quantities, of course, there is also a lot of coffee grounds, which in most households simply goes into the garbage. Coffee grounds can be used in a variety of ways, for example, as a cheap and environmentally friendly fertilizer - not only for geraniums.
Coffee grounds contain many important nutrients
Coffee is rich in various minerals and trace elements that are not completely dissolved out of the ground coffee during brewing. This leaves plenty of nutrients in the coffee grounds, especially
While nitrogen is important for growth - and especially leaf and shoot growth - summer flowers such as geraniums need plenty of phosphorus for rich flowering. Among other things, potassium ensures that the leaves retain a fresh and strong green and do not turn yellow.
Fertilize geraniums properly with coffee grounds
Thus, coffee grounds is ideal as a supplemental plant fertilizer, where you should not use the powder as fresh as possible from the machine. Instead, the coffee grounds should first cool down and, if you want to mix it with the plant substrate, dried thoroughly. Moist coffee grounds quickly start to mold and spoil the plant substrate. Basically, you can use coffee grounds either from filter bags, from coffee pads or hand-brewed coffee - only coffee from aluminum cans can not be used.
Incorporate coffee grounds into the substrate
Coffee grounds can be dried by spreading the moist mass on a flat plate, etc., and place in a dry, warm and bright place. Finally, dry coffee grounds can be incorporated into the substrate both when planting or repotting the geraniums, or even distributed in the root area in the case of already planted flowers. Make sure not to store the coffee grounds on the surface, but to mix it carefully with the substrate.
Dilute coffee grounds
Alternatively, it is also possible to dilute a small amount of coffee with plenty of water and pour the geraniums with it. If you choose this option, take about one tablespoon of coffee per 10 liters of water. However, the mixture should not reach the leaves or the flowers of your geranium.
Tips
Coffee is slightly acidic and therefore great for geraniums that also love a slightly acidic soil.
