Questions

When should I plant dill in Texas?

In Houston, sow outdoors from February 2 to February 16. Across Texas the window opens between January 8 and April 15, depending on the local last frost.

How is this date worked out?

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