Questions

When should I plant swiss chard in Florida?

In Jacksonville, sow outdoors from January 18 to February 15. Across Florida the window opens between January 1 and March 7, depending on the local last frost.

How is this date worked out?

Sow outdoors from 2 weeks before to 2 weeks after the last frost. Frost dates are NOAA 1991–2020 averages for the weather station nearest each city.
