Q. I know nothing about planting tomato plants. What are some basics?

A. Here you go!

Tomatoes need sun – at least 6-8 hours a day.

Tomatoes don’t like their feet to be wet. Make sure soil is warm before setting out plants. One of the biggest mistakes you can make is to plant them too early in spring.

Tomatoes need at least an inch of water a week.

Determinate tomatoes set produce fruit at one time, usually within a 2-4 week span. Indeterminate tomatoes produce fruit until frost.

Q. Should I buy plants or start tomatoes from seeds?

A. If you're a novice, buy tomato seedlings. Wait until Year 2 to start your own plants from seeds. You’ll have a better idea what to expect. (Find tomato plant vendors here.)
