How Often to Change Water for Epipremnum aureum Hydroponics
Hydroponically grown Epipremnum aureum, with its fresh and elegant appearance, has become a new favorite among indoor green plants. However, many beginners often cause the leaves to turn yellow and the roots to rot due to improper water changing frequency. Mastering the scientific water changing cycle can not only extend the viewing period but also promote healthy plant growth.
Complete Analysis of Water Changing Cycle for Hydroponic Epipremnum aureum
Key Care Points During the New Root Development Stage
For branches without roots, it is recommended to use tap water that has been aired for 24 hours. During this period, the water should be changed at a high frequency of 3-4 days per time. Add 3-5 drops of specialized nutrient solution each time, and combine it with trimming the browning tissue at the cut, which can shorten the rooting cycle to 7-10 days.
Mature Root Care Stage
In spring and autumn, changing the water every 20 days is best, keeping the water level covering 2/3 of the roots. In the summer, when it's hot, increase the frequency to every 15 days, and in winter, when it's cold, extend it to 30 days, using water with a temperature difference of ±2°C from the room temperature.
Seasonal Changes and Their Impact on Water Quality
Microbial Control Strategies
In summer, add a chlorine dioxide disinfection tablet (0.5mg/L) every 2 times of water changing, which can effectively inhibit the growth of green algae. In winter, place an activated carbon packet after changing the water, which can continuously absorb impurities in the water.
Professional Water Changing Operation Process
Follow a five-step method: pour out old water → wash the bottle with a soft brush → disinfect with potassium permanganate → trim blackened and rotting roots → add new water. Be especially careful to retain 1/3 of the original water mixed with the new water to avoid drastic fluctuations in the pH value.
Scientific water changing combined with regular supplementary lighting (2 hours of scattered light per day) can make the annual growth of Epipremnum aureum reach 40-60 cm. When the water surface shows an oil film or the root mucilage layer thickens, it is the best time to change the water.
