Tomatoes

I have about 8 tomato plants, only one is heirloom variety. I am yet to see fruit on this. Most of the tomatoes are pretty small. Roma tomato plant is not doing that well. The heirloom tomato plant is growing well and it has such distinct large leaves. I planted marigolds in front of tomato plants to deter aphids. I also sprayed chili pepper, garlic spray and there is no more aphid problem. Hoping to get some harvest soon.
