Cultivation methods and precautions of wood fragrance

1. Maintenance methods

1. Temperature: In comparison, plants grown in warm places will grow better than those grown in cold places. Therefore, the temperature around it should be adjusted to around 20 degrees. It has good cold resistance and can be brought indoors later, but it cannot be kept in a cold environment for a long time, otherwise it will be frostbitten.

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 lack of water is serious, the leaves of the plant will turn yellow. In winter, watering should be reduced because the metabolic function slows down. Excessive watering will affect wintering. Under normal circumstances, watering once every two to four days is sufficient.

3. Fertilization: When fertilizing it, use decomposed organic fertilizer. During the growing season, it needs to be fertilized once every half a month. After the flowers fade, it needs to be top-dressed. In hot and dry weather conditions, it needs to be thinly fertilized. It needs to be top-dressed once before winter, which can increase the success rate of overwintering.

4. Light: According to research, plants grown in places with sufficient and soft light grow better than plants grown in environments with too strong or too dark light. Therefore, during normal care, try to keep them in an environment with moderate light intensity. If the light is too strong, shade is needed, and if the light is too dark, supplementary light is needed.

2. Breeding techniques

1. Reproduction: You can use the cutting method to propagate costus root. The cuttings you choose should be young branches of the current year, as they are easier to survive. After the cuttings are prepared, apply a little wood ash on the cut to sterilize it, then insert the cuttings into the prepared cultivation soil, adjust the breeding temperature to about 20 degrees, and roots will generally grow in two weeks.

2. Pruning: In autumn, it needs to be pruned once, and the older and poorly growing branches in the plant should be pruned to avoid unnecessary nutrient consumption.

3. Problem Diagnosis

1. Pests: Chafers are the main pest of the plant. They will eat its leaves and flower buds, seriously affecting yield and quality. If you find that the plant is infected with scarab beetles, you can use chlorpyrifos to spray it. However, it should be noted that it should not be sprayed during the flowering period.

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

IV. Other issues

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

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