I grew Bonny Best in a greenhouse in the Yukon this summer. Opened the seed pack on April 1, and was eating our first tomato on July 15. Soaked the seeds 24 hrs and used a 'mini greenhouse' (has a heating pad) with peat pellets to germinate the plants and until they were 3" tall. I babied them for sure all the way along. Anyway, started 18 seeds, got 17 plants, gave 8 away. My nine plants have so far yielded approx. 400 tomatoes, and yes, I have been counting. Many have been very small, like 2x the size of a cherry tomato, but I did not prune these plants practically at all. We have enjoyed them and are saving seeds from them for next year. Very rewarding plants if you take the time and effort to make good soil and give them what they need. Not as tasty as the Brandywines I grew two summers ago so I took off one star. But the Bonny Best were much earlier ripening, and had a lot more production. They were easier plants to grow. The Brandywines had a lot of blossom end rot but that was probably my fault (first time I grew tomatoes, probably needed calcium and a better watering scheme, etc)
