Reply To: Tomato Blight in Polytunnel

[John]

Hi Vivian

Thank you for the input. I had been breaking off individual leaves but my more drastic pruning with secateurs was always into clean stem and, after four days away with no watering for over a week, there is no visible blight and I have lots of ripe and ripening tomatoes.

Perhaps even careful watering of the soil can add too much water to the atmosphere and provide conditions where blight is more likely to settle on the foliage.
