Posted on by

Flagstaff isn’t famous for its long growing season; our average growing season is 103 days compared to Sedona’s 199. Because of this, it is a great idea to take advantage of cool season veggies.  These are items like broccoli and kale that prefer cooler temperatures and actually taste better when matured in cold weather.

Here is a list of cool season veggies that can withstand temperatures as low as 29° F along with their harvest times:

  • Carrots (September-November)
  • Beets (September-October)
  • Cauliflower (July – October)
  • Swiss Chard (April-February)
  • Lettuce and Salad Greens (July-October)

Here is a list of frost hardy vegetables that can withstand temperatures as low as 25° F and their harvest times:

  • Cabbage (August-October)
  • Kale (August-March)
  • Broccoli (July-October)
  • English Peas (July-September)
  • Spinach (July-November)
  • Mustard Greens
  • Leeks (October-February)
  • Radish (July-October)
  • Brussel Sprouts (December-March)

Keep in mind that it is very likely we will continue having warm days throughout September, so you will still want to make sure your plants aren’t drying out. Mulching is also a great idea to help keep your soil moist and stop your sensitive plants like broccoli from bolting. Mulching is a great idea this time of year for perennials, shrubs and trees  as it not only helps with water retention but also moderates soil temperatures, protects shallow-rooted plants from freeze damage and it improves the nutrients in your soil.
