Hydroponic Cultivation Method for Water Lilies
To perform hydroponic cultivation of water lilies without soil, seeds need to be soaked for about 7 days for seed germination treatment. Water should be changed daily to maintain clean water quality and promote better germination. After the water lily seeds germinate, it is necessary to add nutrient solution in a timely manner because there are not enough nutrients in the water to meet the normal growth needs of water lilies. When caring for hydroponic water lilies without soil, attention should be paid to replacing water regularly, generally replacing water quality every 5-7 days to avoid cloudy water quality and bacterial growth.
Hydroponic Cultivation Yield of Water Lilies
Hydroponic cultivation of water lilies is beneficial. Water lilies are aquatic plants by nature, so hydroponic cultivation is possible. The annual yield of water lilies cultivated without soil is very high, generally used for ornamental purposes, and the profit is relatively considerable due to low costs.Hydroponic Cultivation Techniques for Water Lilies
Hydroponic Cultivation Process for Water Lilies:1. Prepare materials: To perform hydroponic cultivation of water lilies without soil, a larger hydroponic container is needed, and river or lake water can be used directly for hydroponics. If using tap water, it should be exposed to sunlight for 1-2 days before use. Nutrient solutions and healthy, plump water lily seeds should be purchased at the flower market.2. Seed Soaking: One of the most important steps in the hydroponic cultivation method for water lilies is to make an opening in the seeds. A suitable hole should be ground on the concave end, and then soak them in clean water for about 7 days for seed germination treatment. Water should be changed daily to maintain clean water quality and promote better germination.3. Adding Nutrient Solution: After the water lily seeds germinate, nutrient solution should be added in a timely manner because there are not enough nutrients in the water to meet the normal growth needs of water lilies. Approximately 5-10 drops of nutrient solution can be added to the water every 3 days to supplement the necessary nutrients for water lilies, promoting vigorous growth.4. Later Care: When caring for hydroponic water lilies without soil, attention should be paid to replacing water regularly, generally replacing water quality every 5-7 days to avoid cloudy water quality and bacterial growth. It is also necessary to observe the roots and leaves, trim any decayed parts in a timely manner, provide sufficient lighting and good ventilation, and keep the water lilies healthy and robust.Key Points of Hydroponic Cultivation Technique for Water Lilies:1. Soil: In spring, plant water lilies horizontally in soil rich in organic matter. The soil in the pot should not be too much, and the pot opening needs to leave a gap of 15-20 cm for water storage. After planting, do not fill the pot with water, and it is best to keep the soil layer above 2-3 cm to facilitate heating and ensure survival rate.2. Water Level: Gradually increase the water level as the plants grow. In summer, the water level can be appropriately deepened, and water should be changed in a timely manner to maintain clean pot water; before winter, deepen the water level in the pond to keep the rhizomes below the ice layer for overwintering.3. Sunlight: Place water lilies in a sunny and well-ventilated environment for care. They open during the day and close at night. Long-term growth in shaded areas can lead to weak growth.4. Temperature: Cold-resistant water lilies can naturally overwinter as long as the water level is maintained in winter. Non-cold-resistant water lilies have higher requirements for air and water temperature and should be stored in a greenhouse with a temperature not lower than 15℃.5. Fertilization: During the growth period of water lilies, if the leaves turn yellow and thin, with weak growth, topdressing is needed. Liquid fertilizer should be avoided, and urea, potassium dihydrogen phosphate, etc. can be used as topdressing for potted plants. For pond planting, cake fertilizer, farmyard manure, urea, etc. can be used as topdressing.6. Pruning: Water lilies can be pruned, and residual flowers and withered leaves should be removed in a timely manner after flowering.Precautions for Hydroponic Cultivation of Water Lilies
1. When planting more than 2 bulbous stems, they should be of the same species and planted together to avoid nutrient competition between plants, which can cause weaker plants to be shaded by stronger ones and result in poor growth.2. Attention should be paid to controlling the water level during different growth stages. In the early growth stage, the water level should be kept shallow to prevent leaf exposure to air; during the peak growth stage, the water level should reach the maximum; in autumn, lower the water level and raise the water temperature to allow the leaves to receive sufficient sunlight, enhance photosynthesis, and promote the growth of water lily rhizomes and lateral buds; before the water surface freezes in winter, deepen the water level once to keep the top buds below the ice layer for safe overwintering.3. To prevent eutrophication of the water body, it is best to use tough, absorbent paper to wrap the fertilizer, poke a few small holes, and place it in the water to slowly release nutrients. Stop topdressing in autumn when the stems and leaves of water lilies wither and are about to enter the dormant period, as fertilization can cause root rot.Declaration: The content of this article, "Hydroponic Cultivation Method for Water Lilies," is compiled by flower enthusiasts.

Symbolism and Meaning of Water Lilies
Water lilies, also known as midday flowers or sleeping beauties, have a dignified flower posture and a clear color. They symbolize a pure heart, innocence, and purity. They are considered the national flower in Thailand, Vietnam, and other countries.
How to Cultivate Water Lilies
Soil: Water lilies are not too picky about soil quality. It is best to choose river mud or field mud rich in decomposed organic matter. The soil should be dried and crushed before planting, and sufficient organic fertilizer should be placed at the bottom for base fertilization before replanting water lilies.
Water: When planting water lilies in summer, the water depth should be kept between 20-40 cm for deep irrigation, otherwise it will not be conducive to flowering and growth. The water depth should be maintained regularly. Attention should be paid to keeping the pot water clean during the hot season, and new water should be added promptly when the water becomes turbid.
Light: Water lilies are sun-loving plants and require good ventilation. They should be exposed to about 8 hours of sunlight per day, and can be cultivated using full sunlight. However, they are afraid of strong light, so it is necessary to avoid direct sunlight during noon and strong ultraviolet rays in summer, otherwise the plants may lose their vitality.
Fertilization: When fertilizing water lilies during the growth period, liquid fertilizer should be avoided as it can pollute the water body and cause fertilizer damage. Potted water lilies can use urea, potassium dihydrogen phosphate, etc. as fertilizers, and a small amount of dry cake fertilizer can be directly buried in the soil. Fertilization should not be excessive or too frequent, and a little topdressing during the blooming period and peak growth period is sufficient.
Temperature: A warm environment is most suitable for the development of water lilies, and the temperature should generally be kept between 20-30℃. In winter, to ensure the normal growth of water lilies, the temperature should be kept stable above 10℃, and insulation work should be done.
Functions and Effects of Water Lilies
Ornamental Value: One of the greatest functions of water lilies is for people to admire them. Water lilies are ornamental plants with both beautiful flowers and leaves. In ancient Greece and Rome, they were initially revered as goddesses and offered as sacrifices. In the 16th century, Italian parks often used them to decorate fountains or as outdoor decorations for halls. Now, water lilies are widely used as water landscape theme materials in European and American gardens. In China, they were also used in private gardens during the Han Dynasty, such as the five-color water lily pond in the garden of Bo Lu Hou Huo Guang.
Medicinal Effects: Water lilies have strong medicinal effects, with functions of activating blood circulation and stopping bleeding. The lotus seeds that grow after the water lilies wither are even more precious varieties in Chinese medicine, with the effects of nourishing the heart and kidneys and invigorating blood. The leaves of water lilies also have medicinal effects, which can stop bleeding and remove blood stasis, and have the effects of clearing heat and promoting diuresis.
How to Care for Fresh Water Lily Flowers
When cultivating fresh water lily flowers, first remove the green shell outside the petals. Then find a vase, fill it with 80%-90% water, and fill the water lily stems with water because their stems are hollow inside and have weak water absorption capacity, relying only on the bottom for water absorption, which cannot meet the demand. Finally, insert it into the vase. Note that the water needs to be changed every 2 days.
When is the Best Time to Plant Water Lily Seeds?
The best time to plant water lily seeds is from May to August each year, because water lilies can grow normally during dry and hot weather.
