No question is stupid. Now, it would have been stupid if he didn't ask the question and put lime juice on his plants.I like to think that there are no such thing as a "stupid question".,But this one is the exception.NO, Lime juice & lime for soil is different.If you spray lime juice on your plants/soil you are taking a chance that the will die or be stunted.Now,if you'll excuse me please,I need to go and eat my buffalo wings so i can fly.
