Time to start bringing things in and taking coleus cuttings!
I asked this question on another forum and here is a recipe one of the members gave me. She got it from a local newspaper.

Here is a recipe that I use in my outdoor and indoor gardens all the time. For plants that have summered outside, I water the soil with this and spray the plants making certain to get the underside of the leaves:

1 1/2 tablespoons of baking soda
1 tablespoon insecticidal soap
1 tablespoon cooking oil
1 tablespoon white vinegar
17 cups of water.

I keep a spray bottle of this all summer and spray any insect or disease prone plants. I found this in a garden column in our local newspaper years

Also another member mentioned Cornell had a recipe for this. It might be this one, I don't know but I don't have the link for it.
