Wasatch Front Vegetable Planting Dates

USU Wasatch Front guide for city last-frost dates, hardy/tender planting groups, succession rows, and fall harvest windows.

Climate signals

• USU labels Suggested Vegetable Planting Dates For the Wasatch Front as a peer-reviewed fact sheet Published January 2018.
• The page says the dates are for an average year along the Wasatch Front and that each season has unique weather conditions.
• The Average Planting Date and Planting Range columns are for an initial planting, not every possible succession date.
• The source includes 30-year average last frost dates for Wasatch Front sites so gardeners can choose the closest local reference instead of one statewide Utah date.
• USU says broccoli, radish, carrot, sweet corn, and Swiss chard are well adapted to several plantings spaced a few weeks apart and planted later.
