Any advice for a first time vegetable grower?

I have grown tomaotes for several years and they were my first vegetable. They are pretty easy and you can do them in a container or in the ground. Peel off the bottom branches and bury it deep since all those little hairs on the stalk will become roots. Then put in full sun and water daily. You can add some compost or Fish Emulsion for fertilizer. FYI I wouldn't try Zucchini, Watermelon, or Canetelope as your first one. They take up a LOT of room in your lawn and can be a little overwhelming as your first plant. Good luck!
