The editor provides netizens with a brief explanation on how Eichhornia crassipes survives the winter and shares some small experiences on the plant's winter care essentials, which are sure to be helpful to you. Let's learn about them together!
Eichhornia crassipes is an annual floating herb of the Pontederiaceae family, also known as water hyacinth, water hyacinth seedling, floating lotus, or water narcissus, etc. It is native to Brazil. Originally from the tropics, Eichhornia crassipes has a strong reproductive ability, high yield, and tender texture, making it an excellent feed for pigs. However, it is susceptible to cold temperatures, easily dying in water temperatures below 7°C. How does Eichhornia crassipes survive the winter?
1. Selection of overwintering seedlings. Choose new and strong plants, removing diseased and rotten leaves to be used as seedlings.
2. Building a simple greenhouse: In the winter of cold regions, Eichhornia crassipes usually overwinters in indoor ponds, with about 5 kilograms of plants placed in every square meter of pond area.
3. Eichhornia crassipes should be moved to a separate pond at the autumnal equinox, kept sparse, and allowed to grow in an isolated state. Larger leaves will gradually wither and rot, while smaller ones will increase, which can be used as seedlings for overwintering.
4. During the overwintering period, the greenhouse should prevent high temperatures, ideally keeping it at a low temperature to allow the plants to enter a dormant state. The water temperature in the pond should be maintained between 15-20°C, as temperatures below 7°C can cause death, and above 35°C can lead to rotting of old plants and yellowing, shrinking of new stems and leaves. The greenhouse must be kept well-ventilated and ensure adequate sunlight.
5. Fertilization should be noted during the overwintering period. It's best to use decomposed animal manure, diluted at a concentration of 1:20. When fertilizing, first gently lift the seedlings to expose them to the water's surface, then apply the fertilizer to the water, making sure not to pour it directly on the seedlings.
6. Water change: Generally, change the water every two months, avoiding too large a temperature difference when changing the water.
7. If aphids are found during the overwintering period, they can be controlled by spraying with a 40% carbaryl solution diluted 2000 times with water.
