After hearing so much about late blight in tomatoes and potatoes, I feel like I got away with something. I mean I planted a tomato plant in the same spot three years in a row. It’s even been the same variety the last two years, Early Girl. In order to thoroughly tempt fate, I also planted eggplant and flowering tobacco, also nightshades, in the same pocket. There seems to be no good reason for it to do so well.
It helps that my official tomato spot gets full sun next to a white wall that makes it hotter. And if there’s any breeze at all, the air sweeps through. It helps that my beat-up old tomato cage props it up. But probably the biggest thing I did right was to buy my tomato at a local market.
Phew!

The blight actually only affects tomatoes and potatoes, not other nightshades.
I found out today I have a volunteer tomato in a pot on my back deck. Probably too late to fruit. I’ll try to get you a picture.
Good to know. You could still get fruit from that volunteer. The question is whether it will ripen on the vine. I always end up picking a basketload of green tomatoes in October.
