Cultivation methods and precautions of lotus

1. Maintenance methods

1. Temperature: The lotus likes warmth, and the temperature between 15 and 24 degrees is more suitable. In addition, it is relatively afraid of cold. It may get frostbite below five degrees, and water will freeze below zero degrees, so you need to be careful. Of course, the temperature cannot be too high, and more ventilation is needed.

2. Light: Lotus generally likes light, but it is afraid of too strong light. So, in the summer, try to place it out of direct sunlight. You can also provide some shade at noon in other seasons, because too strong light will make its leaves and flowers wilt.

3. Changing water: Generally speaking, the lotus is aquatic, so you have to pay attention to changing water. If it is a small or medium-sized plant, the water surface height can be controlled between twenty and sixty centimeters. The frequency of water changes is generally once every twenty days, but the intervals can be slightly shorter in summer.

4. Fertilization: When fertilizing the lotus, the main thing used is nutrient solution. You can add it after changing the water, but not too much.

2. Breeding techniques

1. Reproduction: It can be propagated by sowing. Because the seeds of the lotus have no dormancy period, they can generally be sown in all seasons. It is more suitable to sow in an aquatic environment. The water can be mountain spring water, and the culture soil can be pond mud, etc. Generally speaking, if sowing is done in spring, it takes about fifty to sixty days from sowing to flowering, and if sowing is done in autumn, it takes sixty to eighty days.

2. Pruning: When pruning the lotus, repairing the root system is a very important part. Because it is usually grown in water, there are often some rotten roots that need to be cut off in time. In addition, yellow and dry leaves can also be cut off in time.

3. Problem diagnosis and treatment

1. Disease: A common disease is "root rot". In addition to this disease, there are also "black spot disease" and others, which harm leaves and flowers and can be treated with chlorothalonil.

2. Pests: The main types are called "spodoptera litura", "aphids", etc. They have strong reproductive abilities and can be controlled by pesticide sprays.
