Got some nice sized German Queen tomatoes coming along this year. I typically plant at least two of these type tomatoes every year. I do not know why but this type grows the biggest tomatoes for me of any I have tried. And I even planted Big Zacs one year and followed every tip in the book with them for growing big tomatoes. They didn't beat my German Queens. (and were ugly as sin to boot)
These tomatoes on the other hand I just treat like any other type I grow and man do they produce some monster tomatoes.
