Geraniums like fat, but it's hard to know what kind of fertilizer they need. So when you buy fertilizer, there will be three numbers on the packaging bag, showing the ratio of nitrogen, phosphorus and potassium. The elements needed in different periods are different. So when you buy it, you need to think about what you need. If it is too troublesome, it is recommended to select the elements that are relatively balanced, and then the elements can be supplemented appropriately.
In fact, maintenance and fertilization are trivial matters. As long as organic compound fertilizer is selected, it has no impact. But the flowering period is different, not only to ensure the good growth of plants, but also to provide sufficient nutrients for flowers. So what kind of fertilizer?
Most of the flower friends know that nitrogen fertilizer should not be too much at the flowering stage of geranium, and the compound fertilizer containing phosphorus should be selected. The amount of fertilizer should also be determined according to the size of the basin. The basin diameter is 20cm, and the amount is 5-10g. The fertilizer should be applied once before flowering, and the fertilizer should be supplemented properly after flowering. Liquid fertilizer can be directly irrigated. If it is granular, it can be buried at the edge of the basin. It is better to be far away from the plant and absorption root.
Sure.
In order to facilitate the lazy to raise flowers, slow-release fertilizer appears on the market, that is, put the fertilizer into the soil, the fertilizer effect will slowly volatilize, and there is no need for repeated fertilization. However, there is no definite time limit for Geranium to absorb fertilizer, and it is not known whether the fertilizer effect has been exhausted. Generally, the slow-release fertilizer can support 6-9 months, and then observe the growth of the plant. When it shows the symptoms of malnutrition (reduced flowers, smaller inflorescences, yellow leaves, slow growth, etc.), it indicates that the fertilizer is exhausted, it is hungry, and it has been hungry for several weeks. At this time, timely supplement the fertilizer, 3-4 weeks will slowly recover.
