Saffron likes to grow in loose acid soil. You can directly go to the flower market to buy specially prepared soil. It can also be prepared with garden soil, fine sand and rotten leaf soil. Add an appropriate amount of base fertilizer and disinfect it before use

2、 Sufficient light

Sunshine is a necessary factor for growth. It prefers sunshine. Although it can withstand semi shade, it can grow well only when it is well illuminated. Therefore, it is necessary to see 4-6 hours of sunshine every day during the growth period, and it cannot be raised in a dark and humid place

3、 Temperature requirements

For saffron, the most suitable growth temperature is about 18-24 degrees. It grows well within this temperature range, so the temperature should be maintained within this range as far as possible. In winter, we must pay attention to keeping warm, not less than 5 degrees

4、 Apply fertilizer

Fertilizer nutrients can maintain the growth of plants. Before planting, you need to add sufficient base fertilizer in the basin, such as rotten cake fertilizer or bone meal. When the growth period requires proper topdressing, the period of rapid growth can be fertilized every 10-15 days to maintain the growth needs

5、 Precautions

From late April to early May every year, its branches and leaves on the ground may gradually turn yellow. It is necessary to dig out the seed ball and store it in a cool and ventilated place. When the climate turns cool in autumn, it will be planted again
