How to grow water lily

1. Maintenance methods

1. Temperature: Whether the temperature is suitable has a great impact on its growth and flowering. Generally speaking, the temperature between 20 and 30 degrees is better. The temperature cannot be too low, and of course it cannot be too high.

2. Light: Similarly, whether there is sufficient light is also a very important factor affecting its flowering, because it is a very light-loving variety. During the growth period, try to get sufficient light every day, only direct sunlight at noon should be avoided. However, generally speaking, there is no need for shade in winter, as light helps it survive the winter.

3. Water level: Since it is usually grown in water, you need to pay attention to the water level. In the early stages of its growth, the water level should not be too high; a slightly lower level is more appropriate. As it grows larger, the water level can be gradually raised. Depending on the season, the water level is lowered in autumn and winter to allow it to spend the winter safely.

4. Fertilization: Fertilization can be done once every half a month, generally using various types of liquid fertilizers. Do not use too much fertilizer, otherwise it may cause water pollution.

2. Breeding techniques

1. Reproduction: Generally, the method of division is adopted. If it is a more cold-resistant variety, it is usually bred in March or April. Select suitable, plump rhizomes and cut them into sections of about eight to ten centimeters. Please note that each root segment must have at least one bud. After that, you can plant it. It is more appropriate to plant five to seven sections in each flowerpot. The water depth can be between 20 and 40 centimeters, and the water content can be increased appropriately in summer.

2. Pruning: Because its leaves are relatively dense, they need to be pruned frequently. The old, dense and dry leaves can be cut off in time.

3. Problem diagnosis and treatment

1. Disease: The most common disease is "rot". It can be treated with carbendazim. However, if you want to avoid this situation fundamentally, you should choose disease-resistant varieties.

2. Pests: There are many types, such as "firefly leaf beetle", "snail" and so on. You can use dichlorvos or furadan, both of which are more effective.
