How to Care for Potted Water Lilies
Today's focus is on how to care for potted water lilies and the correct planting methods for water lily greenery. Here is a detailed introduction.
It's time for the water lilies to bloom again this year.
Water lilies are perennial aquatic flowers, and many families have them in their gardens. They also serve as decorations in the ponds of parks. "Clear water produces lotus flowers, naturally removing decorations," let's talk about the six key points to consider when caring for water lilies.
1. Water Level Control
No matter whether using pots, barrels, or ponds, the initial water level should not be too deep, and it should be gradually increased as the plant grows. For pond-grown water lilies, drainage should be monitored during the rainy season to prevent flooding. However, 1-2 days without water will not kill the plant. The optimal water depth for water lilies is 25-30 cm, and it should not exceed 80 cm. During hot seasons, it is important to maintain clean pot water and replace it when it becomes murky.
2. Sunlight
Water lilies thrive in sunlight. Insufficient light during the growing season can lead to lush stems and leaves but few flowers, or even no flowers at all. If kept indoors for a long time, lack of shade and ventilation can cause green algae to grow on the water surface, weakening the plant and resulting in only leaves and no flowers.
3. Temperature
Water lilies can tolerate cold and can naturally overwinter in ponds. However, they cannot be dehydrated throughout the winter and must maintain a certain water level. For potted water lilies kept outdoors, if the minimum temperature in winter is below -8°C, they should be covered with weeds or agricultural film to prevent the rhizomes from freezing. Keeping them indoors ensures safe overwintering. Alternatively, the water can be drained from the pot around the time of Cold Dew and placed in a cold room at about 3°C to overwinter, maintaining the soil moist but not frozen. In the following spring, the plants should be divided to prevent overcrowding and poor development, which can affect flowering.
4. Dividing and Repotting Potted Water Lilies
Potted water lilies should be divided and repotted once every spring. The pot should have a diameter of at least 40 cm to allow the lilies to spread out fully. The soil should be rich in organic matter, such as loamy soil or garden soil. If the chosen soil is low in organic matter, it should be mixed with compound fertilizer as a base. After transplanting the rhizomes, water thoroughly, and once sprouts appear, immerse the pot in water with the water level above the soil surface. Place the pot in a sunny, well-ventilated area to grow.
It is important to maintain clean water and change it promptly. If changing water, do it in the early morning.
5. Disease and Pest Control
Water lilies are susceptible to aphids and aquatic moths during their growth and development.
(1) Aphids: If there is insufficient light or poor ventilation during the growth period, water lilies can be affected by aphids. To control them, soak tobacco in water, boil it, and then spray it on the leaves of the potted plant. This is a simple and practical method for controlling aphids, which can also be used on other crops, such as roses.
(2) Aquatic Moths: The larvae of these moths damage the leaves of water lilies, spinning silk to fold the leaves together to form a protective sheath and living inside it. They can float freely on the water surface with the protection of the leaves. They should be detected and removed early.
6. Pruning
Removing spent flowers and withered leaves after flowering can maintain the beauty of the plant.
Conclusion:
Water lilies are ornamental water plants that can be seen in many places, not just in parks and gardens. They are also becoming common in homes. Growing water lilies in glass containers is elegant and natural, while ceramic containers add a classical touch. The cultivation of water lilies is relatively simple, so those interested can give it a try.
