1、 Curing method

1. Pot soil: the pot soil of imperial crown is best drained and breathable. Broken tiles are placed at the bottom of the flower pot and prepared by mixing coarse sand and garden soil. In order to have certain nutrients, a small amount of bone powder or rotten leaf soil can also be added

2. Light: it likes the sunny growth environment very much, but it still needs proper shading at noon in summer. As long as there is the sun, it can grow well

3. Temperature: its growth temperature is relatively broad. It can grow well at 5-30 ℃, and can withstand large temperature difference between day and night. As long as the overwintering temperature is not lower than 5 ℃, it can survive the winter safely

4. Watering: the emperor crown itself has the ability to store water, so you don't need to water too much at ordinary times. You can water it after the soil is completely dry, but don't let there be water in the flower pot to avoid rotten roots

2、 Breeding skills

1. Propagation: Emperor crown propagation mainly includes sowing and grafting, but they are troublesome. The germination of sowing method is very slow. Grafting is best in June and July, and the survival rate is OK

2. Change basin: if the emperor crown changes the basin, it needs to trim its rotten roots, and then put them in a ventilated place to dry for a week, and then put them on the basin again. If it is a new seedling within 2 years, it is not necessary to prune the roots, and it can be put on the basin directly

3、 Diagnosis and treatment problems

1. Anthrax: this disease is common and harmful to plants. After discovery, it can be sprayed with 600 times of 65% mancozeb wettable powder in time

2. Insect pest: the most important pest must be red spider. After red spider appears on the plant, there are gray and yellow patches first, and then large pieces of leaves fall off until all of them fall off. It is necessary to kill them with kermite in time

4、 Other issues

1. Edible: Emperor crown is an endangered species, so it is recommended not to eat it. If you are bitten by mosquitoes, you can smear its juice, which can reduce swelling and relieve pain

2. Whether it can be raised indoors: Emperor crown can be raised indoors. It can not only absorb the radiation brought by various electronic equipment, but also play a decorative role, but be careful not to be pierced by it
