What is killing my tomatoes?

Posted by ehsteve (My Page) on

I have four tomato plants in containers, two are having problems with leaves near the bottom turning yellow and dying, one still has new growth occurring near the top but the other one has stopped growing new leaves and the leaves at the top half are small. Other than that the plants look pretty healthy, at least to my untrained eye.

But every day there are more yellow leaves at the bottom and as I remove them the foliage is really starting to thin out.

I had a bit of an aphid problem but in the last week a bunch of ladybug eggs have hatched and the plants are swarming with ladybug larvae so the aphids are vanishing pretty quickly.

The tomatoes are in containers in a Raybo 3-2-1 mix.

Does anyone have any idea what is killing them and if/how I can stop it?

RE: What is killing my tomatoes?

Yellowing of the leaves could be too much water. I can see water rings under the pots. Soil should be kept moist but not soaked. The roots need to breathe. Water early in the day, never in the evening. It could also be insufficient sunlight. They need 6-8 hours per day. Also, try spacing the pots out a little more so each plant gets good air circulation and not touching each other. Prune off the suckers to open up the plants to more light and air. Hope this helps. Good Luck.
