How to cultivate sea daffodils

1. Maintenance methods

1. Temperature: Sea daffodil is suitable for growing in the cool environment of the north. It has strong cold resistance and can grow normally without infection in a zero-degree environment. Its high temperature resistance is very poor, and the temperature generally cannot exceed 25 degrees. It needs to be cooled in summer. The temperature suitable for its growth is usually between 12 and 23 degrees.

2. Watering: Sea daffodils like highly humid soil and have a very high demand for water, so they need to be watered frequently to avoid problems such as yellowing of branches and leaves and cracking of branches. During the spring growing period, you should always pay attention to its growth conditions and water it in time. In summer, you should water it more often. It is best to water it twice a day. This will allow it to grow normally. Watering in summer can also lower its temperature.

3. Light: It does not like the sun to be too strong. It has a strong ability to tolerate shade and prefers a semi-shady environment. Scattered light in the morning and evening is the most suitable for it. It should be kept in a dark place indoors throughout the summer. At the same time, it will not bloom poorly due to the dark environment.

4. Fertilization: It likes fertile soil, and normal growth requires frequent fertilization to ensure normal flowering. It is necessary to add fertilizer about once a month, but be careful not to apply too much fertilizer. A thin amount of fertilizer will be enough, because if the concentration is too high, it will easily burn the roots of the plant, causing it to wither.

2. Breeding techniques

1. Reproduction: Cutting and sowing are two commonly used methods. The best time for cuttings is from May to September. Choose one-year-old branches, and then choose branches that are 20 cm in length and insert them directly into the soil. If you want to sow the seeds, you need to soak them in cold water for three hours and then sow them. They will germinate in a week and you need to spray them with water continuously during this period. However, you will have to wait until three years before you can see them bloom. The cycle will be longer.

2. Pruning: In winter, you need to prune the top of the plant. Some tender shoots will grow on the top in winter, blocking the roots of the plant, causing mold or rot, so they need to be cut off to increase light transmittance.

3. Problem diagnosis and treatment

1. Disease: Rust will cause some brown spots to appear on branches and leaves, and you can spray a solution of carboxin emulsifiable concentrate.

2. Pests: If aphids or red spiders appear, just spray them with omethoate.

IV. Other issues

1. Toxicity: It is not poisonous and is sometimes used in traditional Chinese medicine.

2. Can it be raised at home? Yes, it has high ornamental value, and the secluded environment at home is more suitable for it.
