My allotment tunnel, which I can’t visit everyday, has mesh on the top half of the end doors and a six inch air gap above. I have been cutting off odd leaves and stems with signs of blight over the last 2 weeks but, going away for a week, I decided to cut back all of the foliage and two plants with the start of blighted stems.
In spite of careful ground watering I find some leaves can be quite damp or even wet in the morning, presumably due to condensation.
Fortunately we have been able to process many (too many?) toms but I am hoping that my drastic pruning and stopping watering will fend off the blight and allow toms to ripen although I doubt they will continue to grow.
Any thoughts on what I have done and any hints for next year?
