Timing is everything. To start your seeds on time, you need to know when in relation to the frost-free date in spring to plant them. If you need help determining your spring frost-free date, call your county extension agent who can tell you for certain.
Creating Your Seed-Starting Plan
- Print the seed starting chart below.
- Write your frost-free date in the blank space at the top of the chart.
- Get a calendar and add or subtract the number of weeks in the "Safe to Set Out Time" column. This is the "Setting Out Date" when you can safely plant the crop to the garden. Write it in the last column.
- Take each date from Column 5 ("Setting Out Date"), subtract the number of weeks shown for that crop in column 3 ("Weeks from Sowing") and record that date in column 2 ("When to Start Inside").
- For our Moose Jaw region, I filled in the dates according to the last frost date: May 20th.
