Could Dried Bean Soak Water Be OK To Add To Watering Can When Watering Veggie ?

Question

Would black bean soak water have some properties that might harm the veggie plants. I tried contacting Master Gardeners Hot Line, but they did not know.

Answer 1

The water will contain nondigestible carbohydrates (oligosaccharides) which can cause gastrointestinal distress, and I don't know if that will affect your veggies. That is why recipes say to discard the soak water rather than cook with it.

You might use the soak water for your ornamentals instead.
