The origin of digitalis is Europe, mainly the mountains in the middle and south of Europe. In China, digitalis has been widely cultivated in Shanghai, Jiangsu, Zhejiang and Shandong.
Digitalis likes sunshine, but it also likes shade a little. When the digitalis blooms, enhance the light, which is conducive to the flowering of digitalis. In terms of temperature, the suitable temperature for the growth of digitalis is between 12 ℃ and 19 ℃, but in the process of germination, growth and maintenance of digitalis, the temperature is still different and needs to be adjusted in time. In the growth period, the temperature of digitalis is best kept at about 20 ℃, otherwise, it will grow in vain and reduce flowering.
The soil needed for the growth of digitalis is required to have good drainage and a certain amount of basic fertilizer should be applied, but digitalis can also tolerate certain barren.
Digitalis has a large demand for water and fertilizer. In the process of breeding, we need to do a good job in the management of water and fertilizer. After planting digitalis, timely watering and fertilization are needed to keep the basin soil moist and air humidity at a higher level. In the growth period of digitalis, it needs to be fertilized once every half a month, and various elements should be added frequently. It should be noted that fertilization cannot stick to the leaves.
Digitalis is usually propagated by sowing.
Although digitalis can be used as medicine, its toxicity is also very large. It is toxic in the whole plant. In the process of breeding, we need to pay attention to its toxicity.
Digitalis is often attacked by anthrax, stem rot and leaf spot. There will also be aphids, beetles and whiteflies, which need to be detected and controlled in time.
