I have a problem with 1 of my tomatoes this year where I have a plant getting no flowers and l fed them all the same everything else looks good .It is growing very tall,same soil in all my plants.All other plants have flowers and tomato
growing.
Without full information, it’s a bit difficult to diagnose what is happening with that tomato plant. The first piece is whether you are growing “indeterminate” or “determinate” tomatoes. As we explained to an earlier inquirer, indeterminate tomato plants keep on growing. Their side branches and shoots continue to grow even after fruit is set, and they can be stopped only by frost. This type of tomato continues to flower and produce a lot of fruit, but the tomatoes tend to mature later in the season. Determinate tomato plants tend to stop growing once the plant sets fruit. These plants tend to be shorter and produce less fruit. However, fruit on these type of plants mature earlier than the indeterminate varieties.
Are all your plants the same variety? Is it possible that the blossom-less plant is a different variety from the others, and is just slower to mature?
Secondly, the amount of sunlight matters. To flower and fruit, tomatoes need 6-8 hours of direct sunlight per day. Is it possible that one plant is more shaded than the others?
Also, you mentioned that you fertilized them all the same. If the fertilizer is a high nitrogen blend (which most general purpose kinds are), it encourages lot of lush green foliage but not flowers and fruit. You might want to kick the slow plant into action with a tomato fertilizer. Note that the recent torrential rainstorm may have washed away soil nutrients, so it wouldn’t hurt to apply the tomato fertilizer around all the plants.
Finally, the temperature is an issue. We are in the midst of a terrible heat wave. As the University of Ohio explains here, tomatoes and peppers struggle in extreme heat (daytime 29, night 21), either not producing flowers or producing flowers that quickly fall to the ground.
The good news is that patience may be part of the solution; if the plants are indeterminate, when the temperatures drop, all of them may continue to flower.
Those are some things to consider and some actions to take. Here’s hoping you get a good harvest of summer’s favourite fruit.
