Hi. I am new to veg growing. Last year I lost all my beautiful tomatoes to blight. This year I grew them in a polytunnel and suffered blight again!
What I did do was remove all the green fruit and at home submerged them in a weak bleach solution to see if killing the spores on the outside would save some. So far about 80% have ripened nicely but still have a lot still have two stacking trays to go. Does anyone else do this? Is this just luck?
