why do the leaves of my tomato plants turn yellow then brown while still producing?

Answer 1

If the plants look healthy, it's most likely just the normal process of the plants putting all their resources into producing.

Sometimes too much water or too little makes the leaves turn yellow, then brown. If you haven't overwatered or haven't neglected watering, your plants should be all right. It's normal. Just take off the yellow leaves.
Good luck! Hope this helps.

Answer 2

Either your tomato plant has too much water or too little. I know because I owned 5 tomato plants for several years. You should cut off the dead or dying leaves because the nutrients will try to save the dead leaf, and then just waste food.

Answer 3

More than likely it's the heat. My plants look dreadful, but they are loaded with tomatoes. We are in the low 100s right now and the tomatoes hate it when it's this hot. Soon they will stop producing, but they will usually return when the temps drop.

Answer 4

It's normal. Just pluck off the dying leaves so that the nutrients are delivered to the healthy part of the plant.

Answer 5

Are the plants having a shock to different ammounts of water.

ex. It rains and storms, and then is hot the next day.

Brown, dry leaves mean not enough water.

Yellow soggy leaves mean to much water.
