The Q&A Archives: Tomato Blossom Drop

Question: I once side of my garden I have cherry tomatoes and all is well. On the other side of the garden I have Big Boy tomatoes. The Big Boy now seem to develope blossoms, but then the blossoms rot before the tomato evolves.

What am I doing wrong with the Big Boy's and not the Cherry? What can I do to correct this blossom rot on the Big Boys?

Answer: Cherry tomatoes are among the easiest tomatoes to grow because they will produce well even under less than ideal conditions. The Big Boy plants may be stressed in some way such as needing more water, or there may be poor pollination. Tomatoes will often drop their blossoms when temperatures are extreme or the weather is very dry. Finally, overfertilizing can also cause blossom drop. About the only thing you can control in all of this is the amount of water the plants receive. They'll need an inch or two a week, possibly more, if conditions are very dry. The best way to apply it is by a deep soaking rather than daily light sprinklings. Good luck with your Big Boys!
