How to grow hydroponic epipremnum aureum beautifully
Among numerous hydroponic plants, epipremnum aureum has become a new favorite in homes due to its unique ornamental value and air purification ability. However, many people often encounter problems such as yellowing leaves and root rot during the hydroponic care process. Mastering scientific hydroponic methods not only keeps the epipremnum aureum leaves glossy but also promotes healthy root growth, creating a stunning underwater landscape.
I. Preparation stage of hydroponic epipremnum aureum
1. Material selection and treatment
The choice of hydroponic materials directly affects the survival rate: preferentially select strong branches with 3-5 leaves, and cuttings with obvious aerial roots are more likely to survive. When hydroponically growing the whole plant, thoroughly wash the soil-bound roots, trim blackened roots with a sterilized scissor, and retain the healthy, creamy-white roots. The cut surface can be coated with rooting powder to accelerate the formation of callus tissue.
2. Key points for container configuration
Transparent glass containers are beneficial for observing the root condition, and the container's diameter should match the size of the plant. The water level should be controlled to cover 2/3 of the roots, and when using a planting basket, ensure the bottom always touches the water surface. It is recommended to add ceramsite to fix the plant during the initial hydroponic stage.
II. Key techniques for daily maintenance
1. Scientific water replacement system
The water replacement cycle needs to be adjusted in stages: replace the water every 3 days with sun-exposed tap water during the non-rooting period, and extend to 7-10 days after the roots have formed. In high summer temperatures, add charcoal blocks to the water to prevent water corruption. Retain 1/3 of the original water when changing water to maintain microbial balance.
2. Light and temperature control
Receive 4 hours of scattered light daily and regularly rotate the container for even lighting. Avoid direct western sunlight in summer and keep at least 1 meter away from heating equipment in winter. The optimal growth temperature is 18-28°C, and the water temperature in winter should not be below 15°C.
3. Nutrient supplement plan
After the roots have formed, add a hydroponic-specific nutrient solution every half month, diluted at a ratio of 1:1000. Spray the leaves with a potassium dihydrogen phosphate solution (0.1% concentration) weekly to thicken and brighten the leaves. Pause fertilization during the winter dormancy period.
III. Advanced maintenance management
1. Root pruning and maintenance
When the roots exceed 2/3 of the container height, they need to be pruned, retaining 8-10 cm of healthy roots. Immediately cut off any browned roots and soak them in potassium permanganate solution for disinfection. Change the water every 2 days after pruning to promote wound healing.
2. Disease prevention measures
Regularly check the back of the leaves to prevent red spider mites and remove them physically with a wet cotton swab. In the early stages of water mold disease, add 0.5% hydrogen peroxide. Maintain good ventilation in the environment and avoid prolonged leaf waterlogging to prevent (T-J) disease.
Through systematic maintenance management, hydroponic epipremnum aureum can maintain its lush greenery throughout the year. Mastering the three core elements of water replacement rhythm, light control, and nutrient management, along with regular pruning and maintenance, even beginners can create a crystal-clear underwater green forest. It is recommended to take growth records every month and adjust the maintenance plan in a timely manner based on the root development status.
