Advice I sought on tomato blight recommended throwing the whole lot out, disinfecting the greenhouse etc etc.
I started with this strategy but then..when I got to the last few, which had previously shown such healthy looking growth, I just couldn’t. Maybe they might recover? The Tom Thumb plants didn’t look quite so badly affected either so maybe I could keep those? I know. Tomato blight is a fungal infection so it would mean the spores remained in the air, probably until next year to re-infect.
Interestingly a trip to son and wife in Cardiff, who I had given several plants to before the blight struck, seemed unaffected and there plants were proving to be good croppers. They were semi-outside in a small makeshift greenhouse. No blight!
