Yes, rice water can be beneficial for rose plants, but with some caveats. While not a complete fertilizer, it offers several advantages due to its nutrient content.
Benefits of Rice Water for Roses
-
Nutrient Source: Rice water contains starch and minerals which provide plants with energy and essential nutrients for growth. As stated in one source, "Starchy rinsed water contains plenty of minerals and nutrients that are beneficial to a variety of plants — house and indoor alike: Starch: Rice water contains plenty of starch from the rice itself, which plants use to store energy for growth." [Source 1] This can contribute to healthier foliage and potentially improved blooms. Many online resources, such as YouTube videos ([Source 2], [Source 5]), and articles ([Source 7], [Source 8], [Source 9], [Source 10]) support this claim.

Organic and Gentle: Rice water is a natural and organic alternative to chemical fertilizers. This makes it a suitable option for gardeners who prefer environmentally friendly methods. One article explicitly states that it's a “gentle equivalent to a fertilizer.” [Source 6]
Cautions and Considerations
- Frequency: Using rice water too frequently can lead to a buildup of starch in the soil, potentially hindering drainage and plant health. It's recommended to use it only once a month or so. [Source 6]
- Not a Complete Fertilizer: While beneficial, rice water alone doesn't provide all the nutrients a rose plant needs for optimal growth. It should be considered a supplement, not a replacement, for a balanced fertilizer program. [Source 9]
- Sour Smell: If the rice water develops a sour smell, it indicates fermentation. While not necessarily harmful, it's best to dilute it before use. [Source 4]
How to Use Rice Water on Roses
- Collect the starchy water from rinsing uncooked rice.
- Allow the water to cool to room temperature.
- Dilute the rice water with an equal amount of water before applying.
- Water the rose plants at the base, avoiding wetting the foliage.
- Apply once a month or less frequently.
