If you can find another spot to plant your Cutting's in then why not, better to be safe than sorry.

It's hard to know Wether your soil is contained or not, it depends of the disease, a better closer pic of your plants could help diagnose the diseases, but..... grey mold spores can live underground on dead plant material, i imagine bacterial spot can also...

Sorry about your plants.

I have my tomato's growing in grow bags, and buckets, due to late to blight last year infecting the ground soil, try buckets? If you want.

Yeah put one in the diseasesed area, and the rest in the new area, as an experiment.

What's the difference between the healthy bed and the diseased one? Is sun the same? (especially morning sun, as that has huge factor in stopping that morning humidity).

I'm inclined to say it shouldn't matter so much for foliar diseases, except septoria, that one seems to survive on soil over winter in my garden.

That jungle look of your plants is probably your enemy. Unless you live in a dry climate, that sort of thing will provide lovely conditions for the fungi.

I would start spraying those seedlings with fungicide to be safe.

Unless you have nematode/soil diseases you can plant them in the same bed. I would spray the soil with bleach solution (7oz Clorox per gallon of water) real good before and after planting. That should take care of Gray Mold problem.

But if you suspect nematode ( as it is present in some parts of FL soil ) you should plant in containers using soil less potting mix.

So I planted some seedlings in a bed that previously had potato plants in it. The potato plants fell ill to some disease. Now my seedlings are doing pretty bad. It's like they get soggy spots on the leaves and then dry up to be holes. Basically just falling apart. Any idea what it may be?

My best guess for what that is is bacterial spot, but bacterial spot doesn't affect potatoes. Then again, just because potatoes were diseased there doesn't mean that the disease is one that is necessarily shared with tomatoes. And I notice you did mention you had bacterial spot problems in your spring season, so we know the pathogen for it might be knocking around your property.

The leaf holes look like snail damage to me. Put some iron phosphate pellets out around your plants, and repeat putting them down after it rains.

I agree. The leaves shown in your pictures are fine except for some insects munching on them. I know slugs don't like tomato leaves. But I don'n know about snails.'

Slug/snail damage is only the plants are very small ( seedlings) . Once they get bigger snail/slug/earwig/flea can not cause serious damage. But you can minimize that easily.

So I ended up transplanting one of my tomato plants in the bed in question. I don't think the plant had any spots on it previously, but now it has developed some spots. The plant has actually grown really well and seems to be doing good, but I'm not sure if it will get worse. Just wanted to see if someone could identify this as bacterial spot or speck?

Here is another plant that also has symptoms

I have continued to use Daconil and a copper based fungicide on all of my other plants and it seems to be working. I'm just hesitant to put any of my new tomato plants near my garden for fear of disease, so for now I'll keep them on the other side of my house.

Thanks,
