Strawberry following Tomato doing poorly
We planted a bunch of strawberry plants on an old tomato bed and couldn't figure out why they weren't growing. Too late, we've realized our mistake. Is there anything we can use to make them healthier? Fungicide? Neem Oil?? Any suggestions? Plants are struggling but not dead.

No, there is not treatment that will rejuvenate the plants if they have verticillium wilt. Verticillium wilt is a common soil bore fungus that infects the plant. It plugs up the water conducting tissue of the plant. They might not die but they will never be healthy. Verticillium wilt can exist in the soil for a long time. I suspect you planted verticillium wilt resistant tomatoes at the site and these plants had verticillium and it is now in the soil. I would dig up the plants and plant something which does not get verticillium. Members of the tomato family, strawberries and raspberries all get verticillium wilt. There are verticillium wilt resistant tomatoes and they are very common. There are also some verticillium wilt resistant strawberry varieties. Here is a link to a Fact-sheet from Ohio State which discusses verticillium wilt in strawberries, how to diagnose it and some resistant varieties.
