Cultivation methods and precautions of Bidens pilosa

1. Maintenance methods

1. Soil: It is recommended to use a culture soil made of a mixture of loose and fertile clay and sand for growing Bidens pilosa.

2. Water: There is no need to water the plant intentionally during maintenance. Just wait for the rain and let the rain provide water. But if it doesn't rain for a long time and the soil is very dry, it still needs proper watering to provide moisture.

3. Nutrients: Just apply some organic fertilizer after planting. Fertilize about every 30-40 days. Fertilizers should be diluted before application, and be careful not to apply concentrated or raw fertilizers.

4. Temperature: It likes to grow in a moist and warm place, with the best temperature being between 18-25℃. It will grow faster where the temperature is moderate.

2. Breeding techniques

1. Pruning: After planting Bidens pilosa, pay attention to pruning the messy grass branches at its roots in time. In the later stage, also pay attention to pruning its branches and leaves that have withered due to lack of nutrients. The pruned branches and leaves should be buried in time to avoid affecting other branches and leaves.

2. Reproduction: Bidens pilosa is generally propagated by seeds, and it bears fruit from August to October. At this time, the seeds can be spread and reproduced with the help of wind, water, fertilizer and manure, and then germinate and grow in spring.

3. Problem diagnosis and treatment

1. Yellow leaves: The reason why the leaves of Bidens pilosa turn yellow is because it does not have enough water and fertilizer. At this time, you should apply some farmyard manure and water it once. In about two or three days, the problem of yellow leaves will be solved.

2. Root rot: The reason for root rot may be caused by too much water. The accumulated water will soak at the roots, affecting the normal absorption of water by the roots. If the water soaks for a long time, it will cause root rot.

IV. Other issues

1. Can it be planted in the ground: It is not recommended to plant it in the ground. Bidens pilosa has a strong reproductive ability and a high demand for water and fertilizer. It uses its own growth advantages to compete with other crops for water and fertilizer nutrients, affecting the growth of crops, so it is not recommended to plant it in the ground.

2. Is it poisonous? Bidens pilosa contains toxic substances, so do not touch it, in case you forget to wash your hands after touching it, and then accidentally eat other foods, causing unnecessary trouble.
