Rice washing can remove a significant amount of water-soluble nutrients from the rice grains, and the water after rice washing is often simply discarded into the environment. This discarded water contains several essential plant nutrients, such as (in mg L−1) 40 to 150 of N, 2.57 to 39.72 NH4+, 43 to 1630 P, 51 to 200 K, 8 to 2944 Ca, 36 to 1425 Mg, and 27 to 212 S. (Nabayi, Sung, Zuan, Paing, & Akhir, 2021)
Additionally, the presence of plant growth-promoting bacteria like Bacillus and Lactobacillus spp quite enhanced its enrichment. Their presence in rice water is particularly noteworthy because these bacteria can inhibit plant pathogens, produce phytohormones and siderophores, solubilize potassium and phosphate, and fix nitrogen.
So, Rice water for plants is not a mere assertion, it’s a substantiated scientific fact.
Methods of Creating Rice Water for Plants
Now that we know the scientific backing behind rice water, let’s explore how we can make it ourselves. There are three popular methods for creating rice water for plants: the rinsed type, the boiled type, and the fermented type. Let’s take a closer look at each method.
1. Rinsed Type:
– Begin by taking a cup of uncooked rice and rinsing it thoroughly to remove any impurities.
– Transfer the rinsed rice to a larger container and add four cups of water.
– Allow the rice to soak in the water for approximately 30 minutes.
– Once the soaking period is over, strain the rice and collect the rice water in a separate container.
– Congratulations! You now have fresh, rinsed rice water for plants ready to work its magic on your plants.
2. Boiled Type:
– Start by taking a cup of uncooked rice and giving it a quick rinse to remove any debris.
– Place the rinsed rice in a pot and add four cups of water.
– Bring the water to a boil and let it cook for about 15 minutes.
– Once the rice is cooked, strain it and allow the rice water to cool down.
– Voila! Your boiled rice water is now prepared to nourish your plants.
3. Fermented Type:
– Just like the rinsed method, begin by rinsing a cup of uncooked rice to ensure it’s clean.
– Next, place the rinsed rice in a jar or an airtight container and add four cups of water.
– Let the mixture sit at room temperature for approximately two days.
– During this fermentation period, remember to stir the mixture a few times daily.
– Once the water turns slightly cloudy and develops a sour smell, strain out the rice solids.
– Fantastic! You’ve successfully prepared fermented rice water for your plants.
Fermented rice water can indeed enhance its effectiveness as a fertilizer for plants. The fermentation process can promote the growth of beneficial microorganisms, such as lactic acid bacteria, yeast, and other microbes. These microorganisms contribute to the breakdown of organic matter in the rice water and increase the availability of nutrients for plants.
Understanding the Rice Water NPK Ratio
Now, let’s delve into the vital role played by nitrogen (N), phosphorus (P), and potassium (K) in plant growth. Nitrogen aids in lush green foliage, phosphorus supports root development and flowering, while potassium contributes to overall plant health and disease resistance. To better understand the NPK nutrient content of rice water, let’s take a closer look at the following table:
|Rinsed Rice water
|Boiled Rice water
|Fermented Rice water
As you can see, the NPK ratio varies depending on the preparation method. Fermented rice water boasts the highest concentration of nutrients, making it a potent natural fertilizer option.
Furthermore, beyond the primary NPK components, rice water encompasses minute quantities of additional micronutrients and minerals—namely magnesium, calcium, and iron—that prove advantageous for plant health.
Rice Water for Succulents
Succulents, known for their ability to store water in their leaves, can greatly benefit from using rice water. These plants thrive in well-draining soil but are prone to root rot if overwatered. Rice water provides a gentle and balanced supply of nutrients, making it the perfect choice for succulent care.
However, rice water for plants should be misted in this case. Mist the succulents with rice water during the normal watering to give them the best benefits and avoid overwatering.
Simply dilute the rice water with tap water (1 part rice water and three parts tap water) and fill it in a clean spray bottle before spraying it on the leaves.
So, providing them with rice water in the early hours of the day or the evening would help them give beautiful blooms.
Plants That Like Rice Water
Apart from succulents, many other plant varieties also relish the nourishment provided by rice water. Some of these plants include:
- Spider plants (Chlorophytum comosum)
- Ferns (Nephrolepis spp.)
- Orchids (Orchidaceae)
- African violets (Saintpaulia spp.)
- Peperomia (Peperomia spp.)
Additionally, some indoor plants exhibit good growth when fed with rice water, including aloe vera, lucky bamboo, Chinese money plant, etc
If you’re looking for an easy way to enhance your pothos plant care, jade plant care, or snake plant care regimen—or if you want to grow even healthier garden plants—rice water can help.
These plants have shown remarkable improvement in growth, vibrant foliage, and increased resistance to pests when treated with rice water. So why not give it a try? You might just witness some magical transformations in your garden.
