How to care for round center duckweed
Among many aquatic floating plants, round center duckweed stands out with its unique round leaves and strong adaptability, making it a popular choice for aquarium landscaping enthusiasts. This plant, which can purify water and has ornamental value, requires mastering several key elements for healthy growth and rapid propagation.
Controlling the growth environment of round center duckweed
Temperature and lighting dual protection
Maintaining a water temperature range of 22-30°C is the foundation for the healthy growth of round center duckweed, with special attention needed to maintain a low temperature threshold above 5°C in winter. Providing 6-8 hours of scattered light daily, with light intensity controlled between 2000-3000 lux, full-spectrum aquatic plant lights can be used for auxiliary lighting.
Water quality maintenance standards
Use slightly acidic soft water with a pH value of 6.0-7.5, replenishing the evaporated water volume every 2 days. It is recommended to set up a filtering system to keep the water flowing and regularly use a water quality testing pen to monitor the ammonia-nitrogen content. If the value exceeds 0.2mg/L, immediately change 1/3 of the water.
Nutrition supply plan for round center duckweed
Scientific fertilization methods
During the peak growing season, add a special liquid fertilizer for aquatic plants every 15 days, diluted to 0.5ml per liter of water and then injected. When using root fertilizer tablets, they should be buried in the substrate 5cm away from the plant to avoid direct contact with the roots, which can cause fertilizer damage.
Secrets to accelerating the propagation of round center duckweed
When the water temperature is stable at 26±1°C, the plant will initiate a rapid division mode. Maintain a calm water surface, extend daily lighting to 10 hours, and add potassium-containing nutrients weekly to promote the mother plant to complete the division process within 7 days.
By optimizing the lighting cycle, controlling the proportion of trace elements in the water, and maintaining a stable water temperature, these three core elements, along with regular removal of old leaves and other detailed management, can not only keep round center duckweed in a vigorous growth state but also achieve exponential growth, quickly forming a spectacular water surface landscape.
