We have a small patio garden. My husband planted small tomato plants a few weeks ago. When I went out to the garden today, he has several tomato plants growing, but also 4 or 5 tall plants that are not the same leaf as the tomatoes. He insists they are tomatoes, I say they are weeds.

The weeds have a more defined light green scalloped leaf and is pointed. The tomatoes have rounded deep green leaves. So, I would like to know how to tell the weed leaves from the tomato leaves.
