Vegetable Planting Times



Suggested Vegetable Planting Dates

for the Wasatch Front

by Shawn Olsen, USU Extension Agent


Listed below are suggested vegetable planting dates for an average year along the Wasatch Front.  Of course, each season has its own unique weather conditions.  The “Average Planting Date” is for the initial planting.  With crops such as broccoli, radish, carrot, sweet corn, and Swiss chard, several plantings can be made a few weeks apart and later than the average planting date.


The average date of the last spring frost will vary with location and elevation.  Listed below are the 30-year average last frost dates for various cities.
