I planted runner beans, corn and courgette plants two weeks ago. I also have potatoes that are now small plants. Over the last 4 days, the beans have turned from healthy plants to brown dead plants. The courgettes, corn and potatoes now all have brown patches on the leaves and are heading the same way. The stems and new leaves turn black. I cannot work out what it is - especially as it is affecting so many different plants.
any ideas or practical solutions would be greatly appreciated!
thank you

I was thinking perhaps, like me, you have let the frost get to them? I have lost all of my runner beans but kept my courgettes and corn under glass until later this month (or even till next if the weather turns bad again) My potatoes are kept "earthed up" to protect them from Jack Frost!

have you dug in manure that you bought from a contaminated source. there was a contamination due to the use of herbicides. that has caused lots of problems in the last 2 yrs.
