Hey there!!! Well, last year was terrible. Almost nothing. But my friend that also grows them, had a huge harvest. I think my soil had something to do with it though as my eggplants did poorly also. This year i have my tomatoes and eggplants in pails and so far look great. We'll see how they produce.
On another note, my father grew them year after year with seeds from the previous years and always had a huge harvest.
