Although it is natural to like light, it must be avoided from the particularly strong direct sunlight. When cultivating saffron in greenhouse, half of it should be shaded in spring, summer and autumn. You don't have to shade in winter.
Suitable temperature is more conducive to the growth of saffron. Saffron likes high temperature but not cold. 18 to 40 degrees Celsius is the best environment for saffron. However, it should be noted that the indoor temperature in winter should not be lower than 15 ℃, otherwise, saffron will go into dormancy, the leaves will gradually turn yellow, and finally fall off, and stop growing. So in winter, we should take a special break to keep the saffron warm.
Make sure the soil in the flowerpot is moist enough during the whole growth process, but remember not to water too much to cause water accumulation. Otherwise, it is easy to cause root rot. But it should not be too dry. In winter, when the saffron starts to sleep, it's time to reduce the frequency of watering. When you find that the surface of the basin soil starts to dry about one centimeter, it means that you need to water it. When watering, you need to water it thoroughly. When watering, one of the most noteworthy points must not be when watering. It is easy to cause leaf rot. this is also a point that many people seldom pay attention to when raising flowers
