QUESTION: Should I cut off yellow leaves on tomato plants?
ANSWER: Once your tomato plants are around 12 to 18 inches tall, you may notice that some of the leaves below the first set of flowers have begun to turn yellow or die. With all varieties of tomatoes, you may remove the dead or yellowing foliage as long as it is below this first set of flowers.
With determinate varieties of tomatoes, there is nothing to gain from removing dead or yellowing leaves, or “suckers,” that grow any higher on the plant. (You may choose to remove the “suckers” that grow from where a branch meets the main stem on determinate tomatoes as long as they aren’t higher than the first set of flowers. On indeterminate tomatoes, you may remove all suckers as long as they are not so large that doing so would leave a damaging wound on your plant.)
Indeterminate varieties of tomatoes may benefit from removing dead or yellowing leaves at all heights and more pruning overall than determinate varieties. That’s because determinate tomato plants will flower and set fruit once, so there is a set number of potential tomatoes that can’t be altered much by pruning. With indeterminate varieties that will bloom and set fruit more than once in a season, the benefits of pruning are greater.

Are you suppose to cut off the top stem in order to get more strength in the tomatoe plants once the flowering begins
What causes brown spot on the bottom of the tomatoe.
Caryn Hall says
That’s blossom rot. Too much water. Not enough calcium.
This sounds like blossom end rot.
This means tomatoes have lacked calcium.
You can buy Miracle grow for tomatoes. This includes calcium, and will prevent this.
However, it should be used from beginning of planting— according to directions, only.
You can also give your tomatoes calcium by smashing up egg shells and placing them around the stems of your tomato plants. As you water the plants calcium from the shells will go to your plants.
