It is best not to use whole granular soil for stone flower health, because it is not conducive to plant rooting, and it is best to mix peat soil. Especially when sowing, seeds with granular soil are difficult to germinate. If they are not replenished with water in time, the seedlings will dry up and die. If the original stone flower is small, it can be used as a plant material with smaller particles, and river sand and peat soil can be added to it.
