Temperature: Costus has a certain degree of cold tolerance, but it cannot be kept in a cold place all the time. During maintenance, it is recommended to control the temperature at around 20°C; watering: during the growth period, it needs to be watered twice a week; fertilization: it needs to be top-dressed every half month; light: it needs sufficient light to maintain it. The lighting time should not be less than five hours a day.

1. Maintenance methods

1. Maintenance methods

1. Temperature: In comparison, plants growing in warm places will grow better than plants growing in cold places. Therefore, they should be The surrounding temperature is adjusted to about 20 degrees. It has good cold resistance and can be brought indoors later, but it cannot be maintained in a cold environment for a long time as it will suffer frostbite.

2. Watering: It likes to grow in moist soil, and the soil must be kept moist for a long time. If there is a lack of water, the growth rate of the plant will be affected. If the water shortage is serious, the leaves of the plant will Yellowing, in winter, watering should be reduced, because metabolic function slows down, and excessive watering will affect overwintering. Under normal circumstances, watering once every two to four days is enough.

3. Fertilization: To fertilize it, use decomposed organic fertilizer. During the growth period, you need to fertilize once every half a month. After the flowers fade, you need to top-dress. In high temperature and drought weather conditions, , you need to apply thin fertilizer, and you need to top-dress it once before winter, which can increase the success rate of overwintering.

4. Light: After research, plants maintained in places with sufficient light and soft light grow better than plants maintained in an environment with too strong or too dark light. Therefore, you should try to maintain them as much as possible during daily maintenance. It is maintained in an environment with moderate light intensity. If the light intensity is too strong, it needs to be shaded. If the light intensity is too dark, it needs to be supplemented with light.

2. Breeding skills

1. Propagation: Cuttings can be used to propagate costus. The cuttings chosen should be young shoots of the current year, which are easier to survive. After the cuttings are prepared, dip a little plant ash on the incision to sterilize it, then insert the cuttings into the prepared cultivation soil, and adjust the breeding temperature to about 20 degrees. Roots will usually grow in two weeks.

2. Pruning: In autumn, you need to prune it once. Prune all the older and poorly growing branches in the plant to avoid unnecessary consumption of nutrients.

3. Problem diagnosis

1. Pests: Scarabs are the main pests of plants. They will eat its leaves and flower buds, seriously affecting the yield and quality. If the plant is found to be infected with chafers, you can spray it with phoxim. It should be noted that it cannot be sprayed during the flowering period.

2. Disease: Leaf rust is a common disease of plants. Leaves and new branches may be infected. When the disease is severe, the leaves of the plant will fall off in large areas, seriously affecting the ornamental value. If it is found that the plant is infected with leaf rust, you can use triadimefon to spray the infected area once a week for four consecutive times, and it will be cured.

IV. Other issues

1. Edible: It cannot be eaten, but it can be used as medicine.

2. Other functions: it can be used to make cosmetic essential oils.
