How often to water plants with fermented rice water
There has been a trend of using "kitchen waste fertilizer" in the home gardening community recently, with fermented rice water gaining attention due to its zero cost and high nutrient content. However, controversies over the frequency of use and suitable plant species have never ceased, especially whether delicate roses are suitable for watering with rice water, which has become a common dilemma for新手 gardeners.
Essential knowledge for home gardening: rules for fermenting rice water
The best watering cycle revealed
Rice water naturally fermented for 30 days contains 3.2% nitrogen and rich trace elements.实测数据显示每月1-2次浇灌能使栀子花根系增粗23%. Remember to dilute it at a ratio of 1:50 before use, and water slowly along the edge of the pot when the soil is moist.
Key points for caring for special plants
Acid-loving plants like camellias and azaleas are recommended to be used with pine needle soil, while leafy plants like pothos can be increased to 3 times per month during the growing season. Important note: Stop using immediately if yellow leaves appear after use, and rinse the substrate with clean water 3 times.
Rose care: taboo zones for using rice water
Five-step correct watering method
Rose roots are extremely sensitive to pH values, so it is recommended to test the acidity of the fermented liquid with pH paper (6.0-6.5 is ideal). Step-by-step operation: ① fully fermented liquid ② diluted to a light tea color ③ water around the pot in a circular pattern ④ avoid stems and leaves ⑤ loosen the soil after watering for ventilation.
Emergency treatment plan
If the leaves are accidentally watered, immediately absorb the excess with a cotton swab and rinse with pure water spray every morning for 3 consecutive days. For plants with fertilizer damage, replace the top 5cm of soil and pause fertilization for 2 months.
Practical skills for eliminating odors
Natural deodorant formula
Add 20g of citrus peel powder to each liter of fermented liquid, which can reduce the odor concentration by 78%. Advanced formula: citrus peel + pineapple peel + EM bacteria mixed in a ratio of 3:2:1, sealed and fermented for 7 days to form a natural fragrance.
Mastering these key data can turn kitchen waste into treasure. It is recommended to establish a watering calendar to record the amount used each time and adjust the plan based on the plant's response. When the pH paper shows that the liquid is too acidic, a small amount of wood ash can be added to balance the pH.
