How could I tell if a plant is a weed or not?

You can check for weeds by looking at the shape of the leaves and comparing them to the pictures in your gardening book. Also, you can look at how close the plants are growing together and compare that to what's recommended in your book. Finally, you can pull up some of the plants and examine them closely to see if they have any signs of being a weed, such as yellowing or discoloration.
