Science Buddies: "Ask an Expert"

Hi! I am trying to do a project on the effects of garlic on tomato plants infected with crown gall. I saw the experiment on this website and I am very interested in the topic. However, I can't figure out how to get the crown gall in the first place! How do I infect the tomato plants to begin with? Please help! I really want to do this one. Thanks so much.

Hi Adina,

This sounds like a great project! Whenever you are interested in something, it is very important to research about your topic. How much research have you done on crown gall?

Once you start researching, you'll find it is much easier to understand how to do things instead of just looking at an experiment done before and trying to do a similar project.

Here are some websites for you:
