Benefits of Using Rice Water to Water Plants
In home green plant care, using rice water to water plants is a traditional wisdom widely applied. This nutrient-rich liquid is not only environmentally friendly and economical but also provides special nutrient support for plants. Mastering the scientific usage method can make common household green plants like pothos and gardenia thrive.
Core Value of Using Rice Water for Plants
Promotes Flower Growth and Metabolism
Experiments have shown that fermented rice water contains 0.15% nitrogen and 0.08% phosphorus, which are essential nutrients for plants and can effectively promote chlorophyll synthesis. Regular use can increase the leaf size of Monstera deliciosa by 20% and extend the blooming period of jasmine flowers by 5-7 days, especially suitable for alternating use between foliage plants and flowering plants.
Improves Soil Microenvironment
Rice water has a weakly acidic nature (pH 5.8-6.3) and can neutralize alkaline soil in the north. Using it twice a month can increase the organic matter content of the soil by 12%, especially suitable for acid-loving plants like gardenias and azaleas. Comparative tests show that the yellow leaf rate in the treatment group is 65% lower than in the control group.
Scientific Application Standards for Rice Water
Fermentation Process and Ratio
Fresh rice water needs to be sealed and fermented for 7-10 days until a small amount of bubbles appear, then diluted for use. It is recommended to mix it with water at a 1:4 ratio, applying it every 15 days in spring and autumn, and reducing to 10 days in summer. Adding orange peel during fermentation can enhance the deodorizing effect and increase the amino acid content.
Special Variety Adaptation Scheme
Succulent plants are recommended to apply a 1:8 diluted solution once a month, orchids should use a foliar spray method. Cacti should not be used, and drought-tolerant species like snake plants should be used once a quarter. For hydroponic plants, the added amount should be controlled within 3% of the total water volume.
Advanced Techniques for Using Rice Water
Nutrient Combination Scheme
Pairing it with eggshell powder can supplement calcium, and mixing it with banana peel fermentation liquid can increase potassium. In winter, it is recommended to use it with EM bacteria agents to enhance nutrient conversion efficiency. Avoid using it simultaneously with alkaline fertilizers and maintain an interval of more than 5 days.
Through systematic practice and verification, scientific use of rice water can significantly improve 90% of household green plants. It is recommended to establish a maintenance log to record the application effects and adjust the plan based on plant feedback. When combined with regular fertilizers, it can build a complete plant nutrient system.
