Question

At what time of the year can I first plant them?

Answer 1

You can start tomato plants any time of the year if you have grow lights to give them an adequate amount of light each day (at least 6-8 hours of bright light). Most people in North America start them indoors in late winter/early spring to be set out after the ground is consistently above 50 degrees Fahrenheit. Tomato plants don't do well in colder conditions.
