I've got a question about some tomato plants I have. I have 2 types growing and they are both heirloom varieties (Jim's Big Red, and Pink Belgium Giants....I think). Both types germinated very well and I have planted 9 in various places in my backyard (7 in the ground, 1 in a 5 gallon bucket, and 1 in a raised bed box I built). The ground planted ones are all looking very nice, and 4 very nice looking plants, at least 6 feet tall. Funny thing about the largest plants is 3 are loaded with tomatoes...none ripe yet, but the other large plant has no tomatoes whatsoever on it....loaded with flowers, but flowers are dropping before tomatoes can form. I haven't used any type of Miracle Grow or fertilizer on them at all. Anyone have any ideas??
