Cultivation methods and precautions of bitter vegetable

1. Maintenance methods

1. Soil: This is a wild vegetable that is very easy to grow. It often grows on sandy soil. Because the soil is loose and fertile, it is very suitable for growing bitter vegetables.

2. Water: The amount of water should be appropriate when watering. Too much water will affect the roots due to low temperature and affect growth. If the plant is too small, it will not grow well due to lack of water, so when watering, you should carefully check the amount of water. Usually, it is enough to just make the soil moist.

3. Nutrients: The main harvest of dandelions is their leaves. When fertilizing, use nitrogen fertilizer and add fertilizer to the leaves. This will make the stems and leaves thick and the yield high.

4. Light: It is not suitable for direct exposure to strong light. Because it likes a cool environment, shade is very necessary. Diffused light is more conducive to the growth needs of bitter herbs.

2. Breeding techniques

1. Pruning: When growing dandelions, what need to be pruned are generally the weeds in the field. Because they are relatively small and about the same size as the weeds, blind weeding will damage the dandelions. Generally, we wait until the weeds grow to a certain size and then use manual weeding to solve the problem.

2. Reproduction: The common method of reproduction is sowing. Before sowing, you should water the soil thoroughly, and then after the water has seeped in, scatter the seeds in the soil and bury them shallowly. Seedlings will grow in about a week. Just keep the soil moist and loose.

3. Problem diagnosis and treatment

1. Downy mildew: A common disease in growing dandelions is downy mildew, which should be treated in a timely manner, otherwise it will infect other healthy stems and leaves. Dilute some thiocarb with water and spray it on the stems and leaves. The effect will be seen in about a week.

2. Root rot: There are many reasons for root rot. One is that underground pests bite the roots and cause root rot. You can dilute imidacloprid with water and spray it. One reason is that too much water is used during watering, and water accumulates at the roots, which can cause root rot. Just pay attention to two points.

IV. Other issues

1. How to spend the winter: In order to prevent it from frostbite, a greenhouse should be built for it before winter, and the temperature should be controlled at around 10-15 degrees Celsius, so that it can grow normally in winter.

2. Is it edible? Dandelion is edible. It can be eaten cold or stir-fried. It is cultivated in many areas of my country and is also one of the more common vegetables.
