Just a few days ago I was eagerly awaiting the ripening of these lovely Golden Jubilee Tomatoes and they looked great.
I turn my back for just a few days and the signs of tomato blight
The growing season has been so warm recently, that the combination of warmth and moisture for a short period of time can be ideal conditions for blight. Further details about blight can be found on this useful Blightwatch website
The only thing to do is to quickly harvest all the tomatoes whether ripe or not, and carefully pull up and destroy all infected plants. Home compost is not suitable, this will just spread the disease. Council green waste is OK because they have hot heaps which will destroy pathogens.
So now I have a big tray of green tomatoes. Some will ripen, but most will become blighted soon. Time to make some green tomato chutney
