I have some birch sap that has gone slightly bad and now tastes off. I don't want to waste it so I am wondering if I can use it to water some plants. According to Wikipedia birch sap contains:

"Birch sap contains heterosides (betuloside and monotropitoside), 17 amino acids including glutamic acid, as well as minerals, enzymes, proteins, betulinic acid and betulin, antioxidants,[15] sugar (fructose, glucose and small amounts of sucrose) and vitamins (C and B).

Could this affect plants in a negative way? (I was concearned about the sugar)

I would only use it while the plants are vigorous growing and in vegetative growing stage. If the plants are in slow metabolism because of cool or weak or low hours of lighting, I would not add any to my plants now. It would just be wasting the sap. Spring and Summer would be the best time to use as a soil drench.
