Why You Can Grow Asparagus in Washington State

You can grow asparagus in Washington state because the climate closely matches what this perennial vegetable loves.
 
Here’s why it works so well here:
 

1. Cool Springs and Mild Summers

Asparagus is a cool-season crop that wakes up when soil temperatures reach about 50°F.
 
Washington’s long, cool springs give asparagus crowns plenty of time to send up spears without the stress of sudden heat.
 
Mild summers on both sides of the Cascades also mean the ferny foliage can grow strong and store energy for next year’s harvest.
 

2. Well-Drained Soils Are Common

Asparagus absolutely hates soggy roots, and Washington has plenty of sandy loam and gravelly soils that drain beautifully.
 
From the Yakima Valley to the Skagit Valley, growers have proven you can grow asparagus in Washington state on a commercial scale.
 
If your soil is heavy clay, you can still grow asparagus in Washington state by amending it with compost and planting in raised beds.
 

3. Winter Chill Is a Bonus

Asparagus needs a period of winter dormancy to rest and reset for the next season.
 
Washington’s cold winters provide exactly the chill hours asparagus requires.
 
That dormancy is one big reason you can grow asparagus in Washington state and keep harvesting from the same bed for 15 to 20 years.
