Growing Zone

Senposai Japanese Mustard Spinach grows best in zones , but may do well outside that range as well.

Most leafy greens like the cooler temperatures, but they can generally grow year-round. You want to be aware of the extreme temperature ranges in your region. Refer to the guidelines below:

COLD CLIMATES

  • If you live in a location where the temperatures dip below freezing, hold off on growing until night temperatures are consistently in the 40's.
  • On the occasional dips into the 30's, you can cover your seedlings with a sheet overnight.

WARM CLIMATES:

  • If you regularly experience temperatures above 90 degrees for long periods of time, you may want to focus on herbs and heat-tolerant fruiting plants (tomatoes and peppers) during the heat intensive months.
  • Once temperatures are consistently in the 80's, you can start growing leafy greens.

To find out what extreme temperatures your location experiences, check out the USDA zone for your region.
