Soil concerns after tomato blight
Anyone reading this: I'm interested to learn how you have managed tomato-bed soil after your tomatoes got late blight. Have you been able to overcome it effectively, in a situation where the location & soil you have to work with is all you've got?
After 30-plus years of growing tomatoes, we got late blight for the first time this year. Our soil in the greenhouse (raised beds) is organic and good. Neighbors a few properties down the had 100 tomato plants, grown for their extended family, that got blight at the same time (July). Their soil us excellent, basically a much-enriched clayish patch of ground under a hoop-style greenhouse for the tomatoes. Like ourselves, they had not had blight before.
It's been affecting a lot of people in our valley - some got it last year, some this year. Weather conditions have been highly unusual in both 2010 and this year.
Is it enough to remove the infected plants and burn them, or otherwise get them off your property? I understand the blight can only survive in living tissue. Hence the question: will our soil be okay, or will it be blight prone, if there are fine root fibers left in it over a cold winter?
Experienced and knowledgeable advice is much sought!
