Would it help, hurt, or not do anything at all if I diluted some B vitamins and watered plants with it?

Question

I have some B vitamin complex pills which just recently expired. I was going to toss them away but hate to waste anything if it isn't necessary. If I diluted them in some water and watered my tomato plants with the solution, would that have any effect on the plants? If so, then would it be good or bad?

Answer 1

My dad was a Master Gardner he did that all the time....but I only know of him using 'C' and 'ferrous sulfate' (iron)

Answer 2

Wouln't hurt, won't help any more than miracle grow.

Answer 3

Most plants produces its own B vitamin, so it wouldn't hurt to use it.
