1. Temperature: the narcissus is suitable for growing in the cool environment in the north. Its cold resistance is strong, and it can grow normally without infection in the environment of zero degree. Its high temperature resistance is very poor. Generally, the temperature cannot exceed 25 degrees. In summer, it needs to be cooled down. Generally, the temperature suitable for its growth is between 12 degrees and 23 degrees.
2. Watering: Narcissus likes high wet soil, and the demand for water is very large, so it needs to be watered frequently, so as to avoid the problems of yellowing of branches and leaves and dry cracking of branches. In the spring growth period, we should always pay attention to its growth, timely watering, in the summer, we should go more watering, watering twice a day is the best, so that it can grow normally, summer watering can also reduce its temperature
3. Light: I don't like the strong sunlight. Its ability to withstand the shade is very strong. I like the semi shade environment. Sooner or later, the scattered light is the most suitable for it. It should be cultured indoors in the dark place in the whole summer. At the same time, it will not blossom badly because of the dark environment.
4. Fertilization: I like fertile soil, and need to apply fertilizer frequently for normal growth to ensure normal flowering. It needs to be supplemented with fertilizer almost once a month, but when applying fertilizer, we need to pay attention not to apply too much, thin fertilizer is OK, because if the concentration is too high, it is easy to burn the root of the plant, resulting in withering.
1. Propagation: cutting and sowing are two commonly used methods. The best time for cutting is from May to September. The annual branches should be selected, and then the branches with a length of 20 cm should be selected, which can be directly inserted into the soil. For sowing, the seeds need to be soaked in cold water for three hours, and then seeded. They can germinate in a week. During this period, they need to spray water continuously, but they need to wait for three years before they bloom to watch. The cycle will be longer
2. Pruning: in winter, you should prune the top of the plant. In winter, some buds will grow on the top of the plant, covering the root of the plant, which will cause mildew or fester. Therefore, you need to prune it to increase the light transmittance.
1. Disease: the rust will appear some brown spots on the branches and leaves, which can be sprayed with weixiangling emulsion.
2. Insect damage: aphid or spider will appear, spray Omethoate directly.
1. Toxicity: no poison, it is sometimes used in traditional Chinese medicine.
2. Whether it can be raised at home: Yes, it has high ornamental value, and the hidden environment in the home is more suitable for it
