The potted soil of geranium is made up of humus soil, garden soil and organic fertilizer in proportion. Therefore, it is necessary to turn the pot in autumn to loosen the soil, increase the air, and facilitate the root respiration and growth.
Spring and autumn are the vigorous growth season of geranium, so the fertilization cycle should be shortened. Generally speaking, liquid fertilizer should be applied every seven to ten days, and the fertilizer content should be determined according to the growth of flower bud. Specifically, the fertilizer before the emergence of Geranium plant bud is mainly nitrogen fertilizer, while after the emergence of bud, the fertilizer content is mainly phosphorus and potassium fertilizer.
As for geranium, the water should be appropriate. But in autumn, the geranium enters the peak period of growth, and the water demand increases. The basin soil and the surrounding air should be kept moist all the time, but the water should not be accumulated. Especially in the low temperature overcast weather can not water or fertilize
The habit of geranium is warm in winter and cool in summer, and the suitable temperature is between 15 ℃ and 25 ℃. In autumn, the indoor environment should be kept warm, in line with the appropriate temperature. On this issue, we should pay attention to the ambient temperature around the plant and move it in time.
Geranium likes light, so in addition to avoiding strong light explosion in summer, Geranium should be placed in a place with direct sunlight in autumn, winter and spring to ensure sufficient light, meet its light demand, promote the healthy growth of plants, so as to have higher value
