However the past few years have been especially prone to blight and there are a lot of spores around.
I have just received an alert for this area. This means the conditions are right for blight to strike and you should watch your potatoes and any outdoor tomatoes for signs of early blight spots.
This is very early in the season for such problems and some of the traditional remedies are not appropriate. You may, however, wish to give a preventative spray with Bordeaux Mixture. This would need to be re-applied after heavy rain.
What a pain, eh?
