Rice water, the starchy liquid left after rinsing or boiling rice, has gained popularity as a natural fertilizer for plants. But can it be used effectively for outdoor plant boxes? The answer is yes! Rice water is rich in nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth.

To use rice water as fertilizer, simply collect the water after rinsing rice and dilute it with an equal part of clean water. Pour the mixture around the base of your plants once every 1-2 weeks. Avoid overuse, as excess starch can attract pests or cause mold.

Benefits of rice water include promoting healthy root development, improving soil microbial activity, and providing a cost-effective, eco-friendly alternative to chemical fertilizers. However, it’s best suited for leafy greens and flowering plants rather than succulents or cacti.

For best results, combine rice water with other organic practices like composting and mulching. Happy gardening!
