1、 Curing method

1. Soil: it likes to grow in soil rich in humus. When preparing soil, it can evenly mix rotten leaf soil and coarse sand. In this way, the soil is loose and has good air permeability, and can continuously maintain water, which is very suitable for its growth. In addition, you can also buy nutritious soil suitable for David's growth from the florist

2. Light: it likes sunlight very much, but it can't accept strong direct light. Temporarily move it to a cooler place in summer to avoid direct sunlight. In winter, it can be placed indoors to receive sunlight. Normal sunshine in spring and autumn can be enough

3. Temperature: David is more suitable to grow in an environment of 15-25 degrees Celsius. Its cold resistance is very poor. Even in winter, the minimum temperature cannot be lower than 5 degrees Celsius, otherwise it cannot grow normally. At this time, it should be moved indoors for maintenance as far as possible to avoid frostbite

4. Water: David needs more water. He must be watered when he first planted, but not too much. When watering, it should be watered with a small amount of water for many times. In summer, the amount of watering should be controlled as little as possible to avoid rotten roots due to David. In case of continuous rainstorm, it is best to move indoors, otherwise there may be a lot of ponding. In spring and summer, it can be watered twice a day. In autumn, it can be watered once. Pay attention to drainage in rainy season to avoid root rot

2、 Breeding skills

1. Propagation: David can propagate by cutting, and must provide a small amount of water when planting. Spring is the most suitable for cutting. You need to cut a small section of the plant in good growth condition to produce callus, and then insert it into the prepared matrix for cultivation

2. Change basin: first place it in a place with good light for cultivation for a period of time, and appropriately reduce the water supply, so as to make its branches and cadres stronger and not easy to be damaged when changing basin. When changing pots, some soil should be reserved at the root to avoid damaging the root and affecting the subsequent growth

3、 Diagnosis and treatment problems

1. Insect pest: after the occurrence of insect pest, the medicine can be sprayed appropriately. After finding it, it is best to cut off the leaves with insects as soon as possible to avoid infecting other branches, or remove the insects manually

2. Leaf hair: it is mostly caused by lack of water. You can appropriately increase the watering times, move it indoors and do relevant protection

4、 Other issues

1. Whether it can be cultivated indoors: it is a plant that likes Yang. If the indoor lighting is good, it is recommended to raise it in a place with good indoor lighting conditions. If the indoor lighting conditions are poor, do not raise it indoors, but in a place with good outdoor light

2. Edible: David has no data to show that it is toxic, so try not to eat it. It has no nutritional value, so it is not recommended
