Cultivation methods and precautions of Oxalis

1. Maintenance methods

1. Temperature: Oxalis likes warmth. Specifically, the temperature between fifteen and twenty-five degrees is more suitable for its growth. It is not very cold-resistant, so try to move it indoors in winter. Try to keep it above ten degrees.

2. Light: It is a plant that likes light. During its growth stage, it needs to be placed in a sunny location. In the hot summer when the light is very strong, it can be moved to a semi-shaded position or provided with appropriate shade.

3. Watering: Oxalis is a moisture-loving plant, but it is also afraid of waterlogging. Therefore, when it is growing vigorously, you can water it every two or three days. However, water must not accumulate. When there is too much rain, flood prevention is also needed. In winter, just keep the soil in the pot from completely drying out.

4. Soil: The main requirements are nutrition, air permeability, drainage, etc. It is best to choose soil that is rich in humus and loose.

2. Breeding techniques

1. Repotting: The soil of potted plants can be changed every two or three years. During this period, you can also loosen the soil from time to time. Sandy soil can be selected as the new soil, and river sand, base fertilizer, etc. can be mixed in. After changing it, water it slightly and then place it in a place with suitable temperature and no strong light.

2. Reproduction: The main method used is sowing. Choose a place with deep soil, good drainage and a certain slope as the sowing site. Before sowing, you need to apply some organic fertilizer to the soil and mix it evenly. Then, it’s time to choose the seeds. Plump seeds without diseases or insects are the most suitable. After that, you can officially start sowing. The spacing can be controlled at about fifteen centimeters. After sowing, water thoroughly and they will germinate quickly.

3. Problem diagnosis and treatment

1. Disease: In summer, powdery mildew is more likely to occur, especially when ventilation and light conditions are poor. This disease can cause leaves to rot and even fall off in large areas. Treatment is with thiophanate methyl.

2. Pests: Pests mainly appear in May, mainly "red spiders". Because its leaves are relatively dense, prevention and control are difficult and require spraying of pesticides.
