Why do some of my tomato plants suffer from flowers that fall off at the stem?

Otherwise the plants seem to be very healthy, and I may have tomatoes developing on the same plan that has empty stems.

However, if it continues you should pay a visit to your local Nursery (or Wal-mart) and get a bottle of blossom set. It is in a small spray bottle and you need to squirt it right on the blossoms. Usually by doing this a couple of times the problem is solved for the season.

Reply:might have two much growth and the plant can%26#039;t keep supplying food to all the stems. Might be an idea to prune a few stems out.
Reply:Mine were doing that at first. I read that the blossoms were probably not being pollinated. Try shaking your plants gently in the early morning. I got tomatoes soon after I did that.make up
