Fall Garden 2020

Asked July 1, 2020, 12:21 PM EDT

Hi there,

I am new to the Centennial area (military family) looking to start planning my fall garden. I have researched and gathered a grouping of cold hardy varieties, but I am curious what date you would suggest would be the first frost date for our area?

I am trying to make a game plan on when I can start my seeds!

Thank you so much for your help!

Some very helpful resources are available in the form of GardenNotes:


There is a section specifically for Vegetables, and newcomers find several to be of particular value:

In the following section are the climate summaries. Centennial would be with the Littleton area, #742. The fall frost probability ranges from October 1 - October 14. See this link:
