1. Temperature: the most suitable temperature range is 22-30 ℃. However, if it is in the stage of flowering and bearing, the temperature should be a little lower, which is suitable for 15-20 ℃. Too sultry environment is not good, need more ventilation.
2. Light: Solanum nigrum prefers light, but it also has a certain resistance to negative, but it can't be in a very dark place for a long time. During flowering and other growing seasons, good sunshine is indispensable, otherwise it will affect its flowering and bearing. Too strong direct light needs to be shielded.
3. Watering: Solanum nigrum has a high water requirement, because it is afraid of waterlogging and can not be dry for a long time. Therefore, the requirement for us to water is just right amount, not excessive, nor long-term water shortage. In winter, it is necessary to control water, especially when it is very cold.
4. Fertilization: Solanum nigrum is generally planted in a large area. Apply fertilizer once a week or ten days, mostly leaf fertilizer. In addition, after harvest, an additional fertilization is needed.
1. Reproduction: it can be sown in large area. Because its seeds are very small, we can not directly sow the seeds, but first insert the seeds into the fine sand, mix them evenly and then sow them one by one. After that, it needs to be watered thoroughly, and then keep the substrate moist all the time. About five to seven days later, it will be ready to sprout.
2. Pruning: first of all, when the plant grows to eight to ten nodes, the heart can be removed to promote branches, and then the amount of results will be larger. When the lateral buds grow to 20cm, they also need to be pruned, leaving only two or three nodes about 5cm long. In addition, for dry, aging leaves, also have to be removed in time.
1. Disease: usually, the probability of disease is not too high, but it's better to pay attention to it a little. Too much water will lead to "root rot" and control water at the same time.
2. Insect pest: not too many. Occasionally there are "scale insects", which are familiar to us. We can kill them quickly.
1. Toxicity: it is toxic. Its juice contains a substance called solanine, which is poisonous.
2. Whether it can be raised at home: generally not, it is poisonous and not an ornamental plant.
