I cannot get to the gardening store in time to buy a wetting agent, what could I use as a substitute?

Answer: You can use dish soap as a wetting agent BUT ONLY ONE OR TWO applications. If you use dish soap as a wetting agent more then twice it clog's the pores of the plant suffocating the plant. You would use 1 or 2 drops of dish soap in a quart of foliar spray solution.
