I have a row of Roma tomato plants laden with fruit.
Parallel to them, and a yard away I have a row of Crimson Crush plants.
Roma have been slaughtered completely by blight.
Crimson Crush are virtually unaffected.
I should have known better, and only Crimson Crush and Crimson Cocktail grow on my allotment in future.
