What are the precautions for growing saffron crocus?
Saffron crocus, also called fanhonghua, is a common Chinese medicinal herb. Saffron crocus has the effects of promoting blood circulation and removing blood stasis, treating amenorrhea, postpartum abdominal pain, and stimulating the appetite. In China, the scale of saffron crocus cultivation is actually not large, so people are not very familiar with the cultivation techniques for saffron crocus, and they are even less clear about the issues that need attention when growing saffron crocus. So today the editor brings you an introduction to the precautions for growing saffron crocus, hoping it can help everyone.
1. Soil
The soil for growing saffron crocus is best chosen as humus soil that faces the sun, has good drainage, is convenient for irrigation, has strong water and fertilizer retention, is rich in organic matter, and has a slightly acidic or neutral pH. Only under these soil conditions can saffron crocus grow normally. In particular, overly heavy clay soil, low-lying areas with standing water, shady areas, and continuous cropping land are all unsuitable for growing saffron crocus, as this will lead to poor growth and development of saffron crocus and also make it prone to disease.
2. Temperature
Saffron crocus has the characteristics of preferring warmth and being relatively cold-tolerant, so we should also pay a little attention to the growing temperature when cultivating it. Under normal circumstances, the temperature of the growing site should preferably not exceed 20 degrees, but in winter, the temperature must not be lower than zero degrees. To promote the growth of saffron crocus daughter corms, the temperature at this time is best kept at around 15 degrees, and if saffron crocus is to bloom, the temperature is best between 15 and 20 degrees. So when we grow saffron crocus, if the temperature drops to around 5 degrees, we need to cover it with plastic film, but when the temperature rises again, remember to remove the plastic film in time.
3. Humidity
The growth of saffron crocus requires sufficient water; it has the characteristics of liking moisture but fearing waterlogging and standing water. During the growing period of saffron crocus, we need to water appropriately to keep the field soil moist and promote the enlargement of saffron crocus daughter corms. After saffron crocus is planted, if there is no rainfall for a long time, it should be watered in time, but excessive humidity should be avoided to prevent the daughter corms from rotting. Also, after watering, it is best to carry out intertillage to prevent the soil from becoming compacted due to watering.
4. Fertilization
Saffron crocus has a large demand for nutrients; whether it is nitrogen fertilizer or phosphorus and potassium fertilizer, its demand is relatively large. When growing saffron crocus, for the base fertilizer we usually use decomposed farmyard manure and an appropriate amount of phosphorus and potassium fertilizer. In the early stage of saffron crocus growth, we mainly apply frequent light nitrogen fertilizer to promote the growth of saffron crocus plants. In the later stage of saffron crocus growth, we mainly use phosphorus and potassium fertilizer, with a small amount of nitrogen fertilizer used in combination. Also, when applying topdressing, be careful not to sprinkle fertilizer onto the branches, leaves, or flowers of saffron crocus, otherwise it may cause seedling burn.
That is all for the precautions for growing saffron crocus that the editor wants to introduce to everyone today. I believe everyone now has a general understanding of the above content. If you want to learn more about saffron crocus, you can follow us.
