Before planting it, we should first select the seeds. After the flowers mature every year, we can harvest them. Then we can select the seeds properly to be plump and disease-free. Then we can preserve them.
Its seeds are very small and cannot be planted in too large pots. So when we choose a pot, we need to choose according to the variety of flowers, usually the best pot diameter is about 25 cm, so that the plant is not too small and will not affect its growth.
It likes alkaline soil, so before planting, it is necessary to choose some sandy soil with good drainage and loose and fertile soil to facilitate its later growth, and then add some saprophytic soil and peat soil to it, and then apply a little basic fertilizer to the bottom of the basin, so that the seeds can be planted in and covered with a layer of soil, so as to limit its growth.
After the seeds are planted in the pot, they need to be watered appropriately, and there should be no water at the bottom of the pot, otherwise they will be washed out, and then they will be given astigmatism irradiation, because for the potted plants, the requirements for sunlight are very high, and the sun can't be too big, but they need to be sufficient, and then adjust the temperature to 18 to 25 degrees, and the temperature can't exceed 28 degrees in summer, otherwise it will affect its growth. At last, add some fertilizer, compound fertilizer or fertilizer containing nitrogen, phosphorus and potassium is the best, so that it will grow seedlings soon.
