Growing Dieffenbachia requires well-drained, sandy soil. Give it appropriate light, but avoid exposure to the sun in summer. Humidity needs to be maintained high, but watering should not be too much. Fertilize every 20 days during the growth period, and add some potassium dihydrogen phosphate before flowering. Propagation can be carried out by division, cuttings and sowing. If you encounter pests and diseases, you need to remove the pests, remove diseased branches and leaves, and then use Bordeaux mixture or omethoate for control.

1. Breeding methods

1. Cultivation methods

1. Soil: Dieffenbachia does not have very high soil requirements. Just pay attention to drainage. Do not use clay or alkaline soil. You can use humus soil 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 more afraid of direct sunlight. If it is summer, it needs to be shaded to prevent it from losing water due to exposure to the sun. You can also place it in a semi-shady place to receive some scattered light. But in order to promote flowering, proper light is also needed.

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

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

1 2. Division: Division of Dieffenbachia 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 plant ash to disinfect it. Wait for it to dry before replanting, watering a little.

2. Cutting: Cutting can be done in spring and summer. Cut a young stem about 12 cm long and use it as a cutting, leaving the leaves at the top. Insert it into the sand bed, control the temperature between 25-30℃, and take root in about a month.

3. Sowing: Sowing is usually carried out from March to April. Plant the seeds in loose, fertile soil, water and place in a cool place. Keep the environment moist and germination will occur in 25 days.

3. Pest and disease control

1 , Diseases: Common diseases include leaf spot and anthracnose. Diseased branches and leaves must be removed first and destroyed in a centralized manner. Then spray Bordeaux liquid and put it in a ventilated place to recover.

2. Pest pests: Brown soft scales are the main pests. If the number is not large, you can use bamboo chips to scrape them off, and then use omethoate to kill the larvae.
