Hi Nick: Here's a site or two that might help:
If you buy the plants, put them into the dirt nearly to the first set of leaves, that way roots will grow out of the stem and be stronger. If you have some red plastic to put near the plants, for some reason that helps. Also, plant marigolds near the plants to keep tomato bugs off of them. Good luck

Hi Nick, this is Peggy. We have grown lots of tomatoes and they are really easy to grow. We buy plants from local store and they work just fine. We till the garden and get the soil soft. Dig a hole pour in water (we lace it with miracle grow). We also put preen around the plant ( not on it, be sure to shake all the preen off the plant) preen will prevent weeds coming up. Tomatoes like water and grow bigger with water. Check what kind you want (juice, salsa or just for eating). I know you will do a great job and I hope you enjoy the fruits of your labor.
