How far to move tomatoes to avoid soil fungus
Last year I lost about half of my 30 tomatoes with symptoms that suggested it was possibly Fusarium wilt. So if I do indeed have this or some other similar fungus in my soil is it isolated to those previous planting holes? Will moving my tomatoes over a couple feet be enough to avoid the fungus? If not, how far away would I need to go? Any other tips for dealing with this?

You should move them far enough that there has been no mixing of soil from the root zone or plant residue of affected plants. It is best to avoid soils where any solanaceous plants have been grown. these include potatoes, peppers, eggplant. There are fusarium resistant tomato varieties available. You migt want tot tey some of those.
