How to Overwinter Aquatic Plants in Winter
With the sudden drop in temperature, aquatic plants face challenges such as root frostbite and nutritional imbalance during overwintering. Mastering scientific maintenance methods can not only ensure the safe wintering of plants but also maintain their ornamental value. This article systematically analyzes the key points of maintaining aquatic plants in winter through 5 core techniques.
Light and Temperature Management
Winter Aquatic Plant Lighting Techniques
It is recommended to place the container on a south-facing windowsill to ensure 4-6 hours of scattered light daily. For special varieties such as pothos and hanging orchids, the duration can be increased to 8 hours, using double-glazed glass to insulate from cold air while ensuring light transmission.
Methods for Insulating Aquatic Plants
Adopt a stepped temperature control strategy: maintain 15-20°C during the day and no lower than 12°C at night. Temporary insulation can be achieved with a mini greenhouse made of food-grade PE film, and professional players recommend using smart hydroponic boxes with constant temperature features.
Nutrition and Water Quality Control
Winter Water Change Cycle Standards
Within a 12-15 day water change cycle, it is necessary to focus on monitoring the changes in EC values. When changing water, retain 1/3 of the original solution to maintain bacterial balance, new water should be left to stand for 48 hours to eliminate chlorine, and add hydroponic-specific slow-release fertilizer to prevent root burning.
Key Steps for Root Maintenance
When changing water, gently wipe the root surface with a soft bristle brush and immediately treat browned roots with a disinfectant scissors at an oblique angle. Regularly adding a 0.1% potassium permanganate solution can effectively prevent root rot.
Environmental Humidity Regulation
Use a misting humidifier to maintain 60% environmental humidity and spray the leaves during the noon period. Avoid species with pubescent leaves such as the lucky bamboo, and preheat the water to above 18°C.
By precisely controlling lighting, scientifically managing temperature, and standardizing water quality maintenance, along with optimizing environmental humidity, the overwintering survival rate of aquatic plants can be significantly improved. It is recommended to assess the growth status monthly and adjust the maintenance plan in a timely manner to keep the hydroponic system vibrant throughout the winter.
