This fall, after I wrote the 2016 Tomato Report post, a disease that I suspect is a form of blight infected all my tomato plants. This disease shows up every year. It starts on leaves at the bottom of the plants and works its way up. Extended rainfall seems to help it spread. It can damage fruits if it reaches them. I suspect the disease comes from the soil, so this year I added straw mulch around the tomato stems in addition to the garden fabric that I always use to try to keep dirt from splashing onto the plants. I don’t think this really helped. More information about blights can be found at the Tomato Dirt site.
This year, although the blight apparently infected all the plants, ‘speckled Roman’ and ‘Polish linguisa’ were the worst hit while ‘Corleone’, ‘garden gem’, and ‘garden treasure’ were the least affected.
We’ve now had three mornings when the temperature went below freezing. We covered the tomato, pepper, and eggplant the first two times that we had frost warnings, but around mid-October we decided to pick all the fruit and let the plants die when the predicted low was well below freezing. It was too cold, and the days are getting too short, for fruit to grow and ripen well. Many of the green tomatoes that we picked will ripen in the house, although they won’t taste as good as if they ripened on the plant.
