1. Light: the maintenance of Ranunculus japonicus needs to pay attention to the light management. It is a species that likes light but is afraid of direct sunlight. Especially in April, when the temperature rises, direct light will accelerate the leaves' yellowing and enter the dormancy state in advance. So it should be placed in bright light, but avoid direct sunlight.
2. Soil: buttercup requires loose and fertile soil, rich in organic matter. Because it is bulbous flower, so the content of scale potassium in the soil should be relatively higher, especially potassium fertilizer, which is more conducive to the development of bulbous
3. Temperature: in general, a short period of zero temperature is tolerable, but if it is any lower, it will cause frost damage. Generally speaking, it likes a cold and cool environment. After entering summer, there will be dormant bulbs, which spend the high temperature season of summer in the soil. So when all its leaves are withered and yellow, it is necessary to cut off water and put them in a ventilated environment, so that it can safely spend the summer and enter the cool weather after September, and grow again later.
During the dormancy period, it can be taken out of the original basin, the waste soil and dead roots can be removed, and the new planting soil can be used for planting. When planting, the bulb of Ranunculus japonicus should be covered with soil about 1 to 2 fingers deep, and then it should be poured with water for a time, and then it should be maintained gradually in the open air.
If the basin soil is relatively dry, it can be watered several times to make the soil gradually wet to the normal maintenance level. If the amount of water is too large and absorption is not good, part of the soil will appear in the state of mud, resulting in hardening, which is not conducive to its normal maintenance.
