What if the lotus leaves don't bloom after 2 months?

1. Cause analysis: 1. The light is insufficient. Water lilies are masculine plants and like sunshine. If the light is insufficient for a long time, the stems and leaves will flourish, the flowers will be few, and even the long leaves will not bloom. If it is cultivated in a cool and unventilated place for a long time, it is easy to grow moss on the water surface, which leads to the weak growth of plants and the phenomenon that long leaves do not bloom. Therefore, we should pay attention to giving enough sunshine when cultivating water lilies. Long sunshine is especially needed during flower bud differentiation. 2. Too much base fertilizer, especially too much nitrogen fertilizer, makes the vegetative growth of plants too vigorous, inhibits reproductive growth and affects flower bud differentiation. The quality of cultivated soil is not good. If planted in sandy soil for a long time, it will grow weak due to lack of nutrients, and it will not bloom or bloom badly. 3. If there are too many plants in the basin, there is no limit to the space in the basin. If more than ten plants are planted in each pot, the leaves overlap and are crowded, and the ventilation and light transmission are poor. Central plants will be affected by insufficient light, even if they bloom, they are mostly light-colored flowers. In addition, due to the deep water layer, pests and diseases will also affect the flowering of water lilies. 4. Potted water lilies that have not been planted for a long time should be planted once every 1 ~ 2 years in early spring. If you don't plant for a long time, don't change pots. Then the roots in the basin are congested together, which leads to poor root development and weak plant growth, which will affect flowering. 2. Cultivation method of water lily: 1. Water lilies, also known as water lilies and meridian lilies, belong to perennial aquatic flowers of Nymphaeaceae. Native to East Asia, I like strong light, high temperature, humidity and well-ventilated environment. Cold-resistant, but avoid freezing. The choice of soil is not strict, but fertile soil rich in organic matter is better. Propagation can be accomplished by dividing plants or sowing. Generally, the rhizome is dug out in late March, cut into small pieces with the length of 10- 15 cm, and then planted. The sowing method is potted in March-April, and the temperature is kept at 25-30 degrees, and it can germinate in about half a month. When the seedlings have 3-4 true leaves, they are planted in pots. 2. Potted water lilies should be changed once a year in spring. When changing pots, it is best to choose pots with an inner diameter of more than 30 cm, so that plants can fully stretch and grow normally. Make the leaves bigger and the flowers bigger. Pot soil is pond soil or garden soil. Put a few hoofs or broken bones at the bottom of the pot as base fertilizer. After planting the rhizome, cover it with a layer of topsoil such as river sand and mud, and pour enough water. After budding, soak the pot soil in water, the water surface is slightly higher than the soil surface, and put it in a ventilated and sunny place for maintenance to keep the water clean. With the increase of temperature and the extension of leaves, water should be gradually added. It grows vigorously in summer and the water level is slightly deeper. Irrigation can be up to 20 cm deep, but the leaves can't be flooded. If you want to change the water, it should be done in the early hours of the morning. 3. Pay attention to keep the basin water clean in hot season, and cut off dead leaves, petioles and pedicels in time after flowering to prevent nutrient consumption and keep the plants beautiful. But if the flowers wither and sink into the water, they must not be cut off, so as to complete the fruiting period. During the growing period, if the growth is not prosperous and the leaves are small and thin, you can bury a little cake fertilizer or urea next to the roots. Water lily is a positive plant, and it needs plenty of sunshine during its growth. If it is maintained in a cool place, the water surface is easy to grow moss, and the plants grow weakly, with only long leaves and no flowers. Generally, water lilies can bloom in potted plants for one year. After flowering, when the leaves wither, the roots should be taken out of the soil and hidden in a greenhouse with water or sand. You can also pour out the basin of water before and after the cold dew festival, cut off dead branches and rotten leaves, and move into an ice-free room for the winter. The next spring, potted again.
