Blight arrived in my garden today (19th Aug), which is later than usual - unfortunately I seem to get it every year these days. However, my tomato plants are well advanced, and lots of the fruit has ripened already. I have picked a lot of the remaining fruit, for ripening off the plants (indoors if necessary).
I have inspected my tomato plants very carefully, and removed any infected leaves / fruits. I will do this again at least twice a day from now on, and I will pick any fruit that shows signs of turning colour (other than brown that is!!)
