First, the culture method and substrate requirements of Lythrum japonicum 1
Melaleuca leuca is suitable for growing in deep, loose and breathable soil rich in humus. When potted, peat soil, perlite mixed with humus soil and river sand can be selected as the culture soil, and then the soil should be changed every 1 ~ 2 years. At this time, it should be combined with ramet propagation, and then mixed with soil again for potted maintenance.
2. Environmental management
Melaleuca likes to grow in sunny environment, and it can grow normally even under strong light. Strong cold resistance, but not suitable for strong light irradiation. Astigmatism can be moved in midsummer, and it should be placed indoors in winter in case of frost, so as not to be affected by freezing.
3. Water management
Melaleuca likes to grow in high humidity environment. During the growing period, the soil in the basin should always be moist, and the principle of watering in spring is wet and dry. Water 1 ~ 2 times a day in summer, and keep the air humidity at about 80%. Water evaporates slowly after autumn, and can be watered 2 ~ 3 times a week.
4. Fertilization management
Fertilization management is one of the cultivation methods and matters needing attention of Lythrum japonicum. Because Lysimachia is a fertilizer-loving plant, it is necessary to ensure sufficient fertilizer in the peak season, especially in spring and summer, nitrogen fertilizer or compound fertilizer should be applied once a month, and compost can be applied appropriately after autumn, with thin fertilizer as the main fertilizer.
Second, matters needing attention
There is a high demand for water quality during the growth period of Lythrum japonicum. Water mainly comes from tap water or exposed rainwater or river water. It is forbidden to use polluted water, otherwise root rot will easily occur. In addition, water should be given in the morning and evening in summer and at noon in winter to ensure the normal growth of roots.
