For the past 4 years my dad has had problems with his tomato patch,
a patch that he grows between 14 and 16 plants every year (Zone 5
Chicago). Thanks to the discussions on this newsgroup, it appears his
tomatoes had (and still have this year) blight. The leaves get blotches,
produce one round of tomatoes, and completely whither away and die. Over
the years he still got a huge load of tomatoes and ironically last year
was a record haul however he didn't like how the plants looked after they
produced their fruit and he wasn't getting any secondary or continuous
growth after the first round. So I convinced him to not compost any of
the dead plants this year and move the tomato plot somewhere else next
year.

I'm wondering, after 4 some years of blight, how many years will it take
before he can grow tomatoes there again? Next year the plan is to grow
wildflowers in the plot and I plan to do a fall planting of seeds for
him. My dad likes to grow herbs and other veggies and I'm wondering if
that would be OK to do there while the plot heals or should we just stick
to the wildflowers?

Doesnt' really sound like tomato blight. But maybe there is more than one
disease that gets the "blight" label. Here is one page I found that tells
about tomato blight. http://www.thegardenhelper.com/blight1.htm

Tomatoes are very sensative to walnut trees in the soil near where they are
planted. Are there any walnut trees within 50 feet of the tomatoes? Here
is a link showing walnut tree wilt. Also other tomato diseases.

There are other trees that produce Juglone, the chemical that causes the
wilt. Check out this site for a list of those trees.
