Growing Parsley in Utah

Parsley in Utah's Climate

Parsley grows during the cooler months, producing abundantly from October through April. Its frost tolerance is an advantage during your occasional cold snaps. More heat-tolerant than cilantro, so it produces longer into spring before bolting.

Soil Considerations for Utah

Alkaline desert soils. Low organic matter. Saline soils in some areas. Heavy amendment with compost and sulfur needed.

Utah Climate & Growing Season

Arid climate. Intense sun. Low humidity. Wide temperature swings. Irrigation essential everywhere.

Growing season length varies across Utah: Wasatch Front (SLC) (6a, 6b, 7a) has a last frost around Apr 20 - May 10, while Southern Utah (6b, 7a, 7b) sees frost end around Apr 10 - May 1. This difference matters for parsley — adjust your planting dates to match your specific region.

Growing Tips

Parsley seeds are notoriously slow to germinate — soak overnight before planting. It's a biennial: lush leaves year one, seeds year two.

Companion Planting

Plant parsley alongside these companions for better growth:

Tomatoes Asparagus Corn

The Bottom Line

Parsley can be grown successfully across Utah, but your exact planting dates depend on which region you're in. Wasatch Front (SLC) gardeners should plan around a Apr 20 - May 10 last frost, while those in Southern Utah can typically plant earlier.
