Q.Neem Oil. I Mixed Neem Oil With Water And Sprayed On My Outside Plants About A Week Ago. There Is Still Some Of The Mixture Left
in my spray bottle. Can I use it again this week or do I have to mix up more? If I have to mix up more, how do I dispose of the old stuff in my spray bottle?

It is safe to use it as a soil drench, though it will not likely be near as effective. For the best results, I would make up a new batch.
