The Correct Method of Watering Flowers with Rice Washing Water
Rice washing water, as a natural organic fertilizer, is widely used in home gardening. Reasonable use of rice washing water can not only promote plant growth but also improve soil structure. However, incorrect watering methods may have the opposite effect. Mastering the scientific method of watering flowers with rice washing water can make your flowers healthier and stronger.
Three Core Steps of Watering Flowers with Rice Washing Water
1. Fermentation Process Analysis
Fermentation of rice washing water requires a wide-mouth plastic container, leaving 1/4 space for gas expansion. The fermentation period is about 7-10 days in summer and needs to be extended to 20 days in winter. When the liquid is light yellow and has a wine lees smell, it indicates successful fermentation. EM bacteria can be added to accelerate decomposition and prevent虫 infestation.
2. Scientific Dilution Ratio
The golden ratio of fermented liquid to water is 1:9 (for seedlings) to 3:7 (for mature plants). The pH value should be controlled between 5.5-6.5 and can be tested with a pH test paper. For acid-loving plants like azaleas and gardenias, a 1:5 high concentration watering can be added once a month.
3. Watering Timing and Method
The best watering time is early morning or evening, avoiding high noon temperatures. Using the immersion pot method allows nutrients to penetrate evenly, with once every two weeks being ideal. For foliage plants, focus on watering the roots, and for flowering plants, foliar spraying can be combined (requires secondary dilution).
Five Advantages of Watering Flowers with Rice Washing Water
Rich in nitrogen, phosphorus, potassium, and B vitamins, it can promote chlorophyll synthesis. The silicon content can enhance plant disease resistance, and the organic matter in rice bran can improve compacted soil. Compared to chemical fertilizers, rice washing water is more in line with the concept of organic planting.
Four Taboos of Using Rice Washing Water
Not suitable for alkaline plants like cacti and wolfberries. Unfermented raw rice water can easily cause root rot, and the frequency of use should be reduced during the rainy season. Do not mix with alkaline fertilizers (like wood ash), and keep refrigerated for no more than 3 months.
Through scientific fermentation and rational application, rice washing water will become a free nutrient source for your garden. It is recommended to establish a usage log, record the reactions of different plants, and gradually optimize the watering plan to make every drop of rice washing water achieve maximum benefit.
