Raw stone flowers are drought and waterlogging resistant, so the permeability and drainage performance should be taken into account when selecting soil. General soil is not good for it, so it must be prepared according to its growth habits. First, perlite and peat can be selected and arranged in a certain proportion, but the cost of this kind of soil is relatively high. Second, you can choose economical river sand and ceramsite to mix in proportion of three to one.
The soil nutrients with good porosity are not high, so it can't meet the needs of the growing stone flowers. So it's time to add nutrients to the soil. Raw stone flowers start to grow in spring. At this time, it needs to apply fertilizer twice a month. When applying fertilizer, you should choose light fertilizer, because raw stone flowers are resistant to barren, and thick fertilizer is easy to burn it. Summer and early winter are its dormancy period, at this time, it does not need too much fertilization, once a month can be, in autumn, it slowly awakens from dormancy, it needs to add nutrients to it, but after flowering, it does not need fertilization.
When applying fertilizer, it should be noted that it can not be applied directly to the root. It should be about 10 cm away from the root to avoid burning the root. Every time when watering, put water on the fertilizer, let the water take the fertilizer to the root system of the plant, so as not to burn the root, but also conducive to absorption, good for the plant.
