1. Soil: for safflower, it is suitable to grow in fertile and well drained soil, and nutritious soil needs to be prepared for domestic breeding. Choose sand loam, peat soil and sand according to 5:2:1 mix, so not only drainage capacity is strong, but also can provide certain nutrients.
2. Lighting: the requirements for safflower lighting are relatively strict. It needs a certain amount of light and can't be exposed to the sun. Indoor culture needs to be shaded in summer, or put in the half shade, and get light in the morning or evening. In winter, it is necessary to put it on the balcony to receive long-term illumination.
3. Watering: I prefer wet environment to safflower, but I am not tolerant of waterlogging. The amount of water to be watered should be controlled, and there should be no ponding in the basin soil. In addition, spray water around regularly to improve air humidity. We should open windows and ventilate regularly to prevent bacteria from growing in humid environment.
4. Fertilization: there is a high demand for fertilizer for safflower. Fertilizer should be applied every half a month during the growth period, and stop applying fertilizer when flowering. After the flower withers, supplement fertilizer in time to promote its growth. Wait until the end of autumn to stop fertilizing and let the plant go to sleep.
The safflower can be propagated by sowing, dividing and cutting. The ball dividing method is more suitable for domestic use and can be combined with basin changing. Take out the plant from the basin, peel off the small bulb of the head, and plant separately into the new basin.
1. Disease: common diseases include spot disease, virus disease, etc. it is necessary to cut off the diseased branches and leaves, then soak the bulbs in formalin, dry and replant them.
2. Pest: the main pest is red spider, which can be killed by spraying with triclosan.
