Cultivation method of Portulaca grandiflora

1. Maintenance methods

1. Temperature: Portulaca oleracea prefers a warm, slightly higher environment. Specifically, the temperature between 20 and 30 degrees is more suitable. In addition, the temperature for breeding can also be maintained within this range. In addition, a too hot environment is harmful to it, so you can be a little careful.

2. Light: Portulaca grandiflora requires more sunlight. Its flowers have a special characteristic: they will only bloom after seeing the sunlight; if it is at night or on a cloudy day when there is insufficient sunlight, the flowers will not bloom. Therefore, in order to ensure that it blooms normally, try to place it in a location with good sunlight.

3. Watering: Portulaca oleracea requires a lot of water during the growing season, but water cannot accumulate. Especially during the flowering period, water cannot be lacking. After late autumn, the growth rate will slow down and you won’t need to water it too much.

4. Fertilization: Liquid fertilizer needs to be used regularly, but the interval does not need to be too short, once or twice a month will be enough.

2. Breeding techniques

1. Reproduction: It can be done by sowing. However, its seeds are relatively small, so you need to choose the appropriate one for sowing. Sowing can be done in spring, summer and autumn. The row spacing can be about six centimeters, and the plant spacing can be about five centimeters. After sowing, you can cover it with a thin layer of soil, or you can leave it uncovered. Keep the temperature above 20 degrees.

2. Repotting: It does not have particularly high requirements for soil and its ability to tolerate barrenness is very strong. Therefore, the interval between repotting can be slightly longer, at two or three years, but it cannot be completely unrepotted. You can choose sandy soil with good drainage, which will have a better effect. After repotting, place it in a cool place temporarily to allow it to adapt.

3. Problem diagnosis and treatment

1. Disease: It may be caused by anthracnose, and the damaged parts are mainly the leaves. You need to cut off all the leaves and then use chlorothalonil. There is also "powdery mildew", which is very common on leaves and flowers, and can also be treated with chlorothalonil.

2. Pests: Relatively speaking, there are not too many. There may be "scale insects" and the like. You can spray some preventive agents in advance.

IV. Other issues

1. Toxicity: It is non-toxic and has medicinal and edible value.

2. Can it be raised at home? It can also be used for viewing and as a potted plant and can be raised at home.
