Jerusalem artichoke cultivation method

1. Maintenance methods

1. Temperature: Jerusalem artichoke has low requirements and good adaptability. The most suitable temperature for it is between 18 and 22 degrees, but a slightly higher or lower temperature will not affect its growth. In winter, its tubers can withstand temperatures as low as minus thirty degrees Celsius. However, if it is the above-ground part, the temperature cannot be lower than minus five degrees Celsius.

2. Light: Jerusalem artichoke is a sun-loving plant. Generally speaking, its tubers can form and grow better if it is kept in light for about twelve hours a day. However, try to avoid too strong sunlight.

3. Watering: Jerusalem artichoke is very drought-resistant and does not require too much water. Moreover, its waterlogging resistance is not very good. Therefore, when replenishing water, you can do so after the substrate has dried, and do not allow water to accumulate. For large-scale planting, waterlogging prevention and drainage are necessary during the rainy season.

4. Fertilization: Jerusalem artichoke does not require much nutrition from the soil. Just choose soil with the right amount of nutrients, and very little fertilizer is needed under normal circumstances. Generally speaking, only two applications of fertilizer are required during the growing season. Once around May, use urea. Once during the budding stage, use potassium sulfate.

2. Breeding techniques

1. Reproduction: It can be propagated by seeds. It is best to sow in the spring, after the thaw. Choose the right tuber seeds. When sowing, the depth is controlled at ten to twenty centimeters, the row spacing is 0.5 meters, and the plant spacing is also 0.5 meters.

2. Pruning: Usually the main thing is to carry out appropriate repairs on its branches and leaves. Because it has high requirements for sunlight, if it is too dense or messy, it will seriously affect light transmission. In addition, after the flowering period, the dead flowers and branches also need to be trimmed.

3. Problem diagnosis and treatment

1. Disease: The main one is "rust". The pathogenic spores will overwinter on the plant and will cause disease when the temperature rises the following year. It can be treated with fenacet. In addition, diseased plants need to be dealt with in a timely manner, and attention should be paid to drainage, density control, etc.

2. Pests: Jerusalem artichokes are not often affected by pests. If there are signs of pests, deal with them in a timely manner.

IV. Other issues

1. Toxicity: Jerusalem artichoke itself is non-toxic and harmless. However, it will contain toxic substances after it becomes moldy.

2. Can it be grown at home? Yes, but generally people will not grow it as a potted plant at home because it is not for viewing.
