borage help prevent hornworms on tomatoes?
last year both my cherry tomatoes and full size tomatoes were attacked by massive hornworms. I had raised beds in the yard as well as large trugs on the deck - used bagged organic soils for trug and raised bed bagged soil blended with our soil which is acidic. I read somewhere that borage deters those hornworms- true?

It can help, but they will eat if they find a food source. I don't like to recommend specific products, but for cases like this, I will.
Foxfarm has a product called Force of Nature- Miticide. It is completely organic and works for a broad range of pests. It is what I use, personally, and the only thing that I have used since I started using it pre-release to the public.
Spray the plants once per week, or whenever you need, as it won't harm any plant.
I use it around the home, as well! It kills on contact.
