How to grow evergreen flowers

1. Breeding methods

1. Soil: The soil requirements of Dieffenbachia are not very high. Just pay attention to drainage. At the same time, do not use clay and alkaline soil. You can use leaf mold mixed with sand as the substrate, and put broken tiles on the bottom to increase its drainage capacity.

2. Light: Dieffenbachia is suitable for growing in a semi-shady environment and is afraid of direct sunlight. If it is summer, it needs to be shaded to avoid excessive sunlight causing it to lose water. You can also place it in semi-shade to receive a certain amount of scattered light. But in order to promote flowering, proper light is also needed.

3. Watering: Dieffenbachia has high requirements for air humidity, and the potting soil should not be too wet. Water sparingly, generally just a little when the topsoil is dry, to keep it slightly moist. You can sprinkle water around, once in the morning and once in the evening in summer, to keep the environment moist.

4. Fertilization: Dieffenbachia needs sufficient fertilizer during the growing period. Fertilizer should be applied every 20 days. The fertilizer can be decomposed liquid fertilizer, and the effect will be better when combined with new lipid film. Fertilization should be applied more frequently in early summer, once every 10 days. Before flowering, you can add a little potassium dihydrogen phosphate to promote flower bud differentiation.

2. Breeding techniques

1. Division: The division of evergreen is usually carried out in spring and can be combined with repotting. After taking out the plant, cut off the rhizome at the base and apply wood ash for disinfection. Wait for it to dry, then replant and water it a little.

2. Cutting: Cutting can be carried out in spring and summer. Cut a tender stem about 12 cm long as a cutting, and keep the leaves on the top. Insert it into the sand bed, control the temperature between 25-30℃, and it will take root in about a month.

3. Sowing: Sowing is generally carried out in March and April. Plant the seeds in loose, fertile soil, water them and place them in a cool place. Keep the environment moist and it will germinate in 25 days.

3. Pest and disease control

1. Diseases: Common diseases include leaf spot and anthracnose. First remove the diseased branches and leaves and destroy them in a centralized manner. Then spray Bordeaux liquid and place it in a ventilated place to recover.

2. Pests: Brown soft scale is the main pest. If the number is small, you can scrape them off with bamboo strips, and then use omethoate to kill the larvae.
