Question
Hello, i am glad to find a great educational site.
i want to know what type of solution would be an efficient weed killer. And also i don't know how to revive a wilted plant.
Hi Travis: Thanks for your question.
If you don't want to use a commercial weed killer, you can use a salt solution (hypertonic) or agricultural grade vinegar (NOT household vinegar). Now, you already knew the answer to this question, didn't you? Rain water is hypotonic and it doesn't kill weeds, does it?
Why is the plant wilted? A root fungus? Failure to provide water? Too many questions to answer easily.
Hope this helps! Write back if you have more questions.
