Dealing with Blight
I’ve been doing some research.
The good news is that the fungus responsible for Late Blight doesn’t overwinter well. As long as there isn’t any infected tissue kept out of the weather, all of the fungal spores will be killed by cold.
The problem: it likes to overwinter in potatoes. And people grew quite a lot of potatoes this year. If they can all be encouraged to double-check to make sure that they didn’t leave any tubers in the ground, we’ll probably be able to grow tomatoes successfully next year.
Finding all of the tubers is hard, though. And just one infected potato is enough to destroy every tomato plant in our ninety-eight plots.
