How to stop potato blight

A good start can help you to prevent blight in your potatoes. Choose an airy plot with a good amount of space between your potato plants. Rotating crops is also important, so don't plant this year's potatoes in the same place as last year's.

What is Potato Blight?

Blight is a  fungal disease, spread by the wind that affects a number of crops, in particular Potatoes and Tomatoes. Blight caused the Irish potato famine and as the word 'famine' suggests, blight can be devastating if not managed and dealt with quickly. In as little as 10 days, Blight can destroy your entire crop of potatoes, which is why Blightwatch provides you with daily alerts as to when Blight is likely to strike, meaning you can check your crop and deal with any infection.

What causes blight?

Blight loves warm, humid weather. the right mix of warmth and damp provides ideal breeding conditions for Blight to thrive. Late summer is usually the time when Blight becomes a real nuisance, however Blight can strike as early as May or June, in the UK,  if the conditions are right. 

Will a greenhouse protect my potatoes from blight?

The short answer is No. Whilst a greenhouse can offer some protection Blight really can and will get everywhere, so it is important to be just as vigilant for potato blight with potatoes grown inside as well as out.
