David's breeding methods and precautions

1. Maintenance methods

1. Soil: It likes to grow in soil rich in humus. When preparing the soil, you can mix leaf mold and coarse sand evenly. This way the soil is loose and has good air permeability, and can continuously retain moisture, which is very suitable for its growth. Alternatively, you can also buy nutrient soil suitable for David's growth from a flower shop.

2. Light: It likes sunlight very much, but cannot accept direct sunlight. In the summer, temporarily move it to a cooler place to avoid direct sunlight. In the winter, place it indoors to receive sunlight. In the spring and autumn, it can receive normal sunlight.

3. Temperature: David is more suitable for growing in an environment of 15-25 degrees Celsius. It has poor cold resistance. Even in winter, the lowest temperature cannot be lower than 5 degrees Celsius, otherwise it cannot grow normally. At this time, you should try to move it indoors for maintenance to avoid frostbite.

4. Water: David needs more water. It must be watered when it is first planted, but not too much. When watering, you should use small amounts of water multiple times. In summer, you should control the amount of watering to be as small as possible to avoid root rot. In case of continuous heavy rain, it is best to move it indoors, otherwise there may be a lot of water accumulation. In spring and summer, you can water it twice a day, and in autumn, you only need to water it once. During the rainy season, pay attention to drainage to avoid root rot.

2. Breeding techniques

1. Reproduction: David can be propagated by cuttings, and a small amount of water must be provided when it is first planted. Spring is the best season for cuttings. You need to cut a small section from a plant in good growth condition, allow it to produce callus tissue, and then insert it into a prepared substrate for cultivation.

2. Repotting: First place it in a place with good light for a period of time and reduce the water supply appropriately so that its branches and stems become stronger and less susceptible to damage when repotting. When repotting, you need to keep some soil on the roots to avoid damaging the roots and affecting subsequent growth.

3. Problem diagnosis and treatment

1. Pests: After an insect infestation occurs, you can spray appropriate pesticides. After discovering it, it is best to cut off the leaves with insects as soon as possible to avoid infecting other branches. You can also remove the insects manually.

2. Leaves wilt: This is mostly caused by lack of water. You can increase the watering frequency appropriately, move it indoors, and take relevant protective measures.

IV. Other issues

1. Can it be grown indoors? It is a sun-loving plant. If the indoor lighting is good, it is recommended to grow it in a place with good indoor lighting conditions. If the indoor lighting conditions are poor, don't keep it indoors, but keep it outdoors in a place with good lighting.

2. Is it edible? There is no data showing that it is toxic. It is better not to eat it. It has no nutritional value, so it is not recommended to eat it.
