We’ve been having a lot of weather recently that is ideal conditions for the spread of blight. It effects tomatoes and potatoes, of which I grow both. Fortunately I am only growing my tomatoes inside this year, so they are less likely (although not guaranteed) to contract it. The potatoes on the other hand are outside and directly in the firing line. I wasn’t that surprised then to find that I had blight on the potatoes when I arrived at the plot yesterday.

I’d been keeping an eye on them, so I caught it early and it was confined to the haulms, and hadn’t reached the roots or the potato tubers themselves.

There’s a bit more detail in the video below, but essentially blight, which is airborne, spreads more easily when the weather is wet, mild and humid. More details about this disease in the UK can be found at: http://www.blightwatch.co.uk
