Blight - can I save my tomatoes?
I have what looks like late blight on a speckled Roma. The neighboring plants (Brandywines, another speckled Roma, other Romas, different types of cherry tomatoes and more) are not affected (yet), although I see a little yellowing on a few leaves near the ground. I'm tempted to take out the blighted plant, even though I feel like salvaging some of the fruit that still looks good. Will that even help prevent spreading, or is it too late to do anything? I have never used fungicides, pesticides or even fertilizer in these beds before. I am kind of a novice and may be wrong about it being late blight, but that seems like the worst case scenario, and it is possible. We live in a dry area of Colorado so I thought we wouldn't get fungus. I water early mornings several times per week.
Is my whole garden doomed?
