Blight on my tomatoes!

Sorry to hear that, it's so disheartening. Nowadays we stick to small bush varieties outdoors: they crop earlier, have less foliage and a neater habit which allows for more air flow. Maskotka, Cherry Falls and Koralik have given a great yield already and look like they'll be finished cropping by the end of the month. Koralik also has some blight resistance. Next year we might try two blight resistant bushes, Lizzano F1 and Losetto F1.

Have you considered blight resistant varieties for outdoors? There are new varieties coming out every year. Here's some I've got on my blight resistant list - Celano, Buffalosun, Consuelo, Crimson Crush, Cocktail Crush, Crimson Blush, Nagina (aka Crimson Plum), Crokini, Romello, Mountain Magic, Mountain Rouge, Mountain Merit, Oh Happy Day, Early Resilience, Honey Moon, Burlesque, Galahad, Defiant. Most of them are F1 of course, and some haven't been released over here yet, but in my opinion the higher price of seed is worth it to not lose a whole crop in a couple of days.
