Hi Charles/Janet,
I grow Tomatoes outdoors here in Kildare.
I grew 5 cvrs this year; Alicante, Aurora, Tumbling Tom, Chocolate Cherry & Black Plum.
I got hit with late Blight about two weeks ago. Aurora & Tumbling Tom were effected but the others are completely healthy.
They were all planted in the same bed 3′ apart. I’m wondering if the fact the effected plants were bush varieties and the others are cordon had an bearing on this?
I can say Alicante, which is my “banker” Tomato crop each year has never gotten Blight.
The other 4 I have not grown before.
Don.
