How Do You Start Growing Asparagus

You start growing asparagus by planting one-year-old crowns in early spring, in a sunny spot with well-drained soil, and then waiting patiently for two to three years before your first real harvest.
 
It sounds like a long commitment, and honestly, it is one.
 
But once an asparagus bed is established, it can keep producing spears for 15 to 20 years or more with very little fuss.
 
That’s why so many home gardeners say that learning how to start growing asparagus is one of the best long-term investments you can make in a vegetable patch.
 
In this post, we’ll walk through how to start growing asparagus step by step, from picking the right spot to planting crowns correctly and caring for them until harvest time finally arrives.
 

How Do You Start Growing Asparagus?

Starting an asparagus patch begins with choosing the right location and planting material, then giving the plants time to build strong roots before you ever cut a spear.
 
Here’s what that process looks like in practice.
 

1. Pick a Sunny, Well-Drained Spot

Asparagus plants need at least six to eight hours of direct sunlight every day.
 
They also hate soggy roots, so the soil must drain well.
 
If your ground stays wet after rain, consider building a raised bed, since standing water will rot the crowns fast.
 

2. Test and Improve Your Soil

Asparagus grows best in soil with a pH between 6.5 and 7.5.
 
Before planting, mix in plenty of compost or aged manure to give the bed rich, loose texture.
 
Good soil prep now means healthier spears for the next two decades.
 

3. Decide Between Crowns and Seeds

Most people start growing asparagus from one-year-old crowns because they save you an entire year of waiting.
 
Seeds work too, but they add another season before you can even think about harvesting.
 
If you want the fastest route to a productive bed, crowns are the way to go.
 

When to Plant Asparagus Crowns

Plant asparagus crowns in early spring, as soon as the soil can be worked and the danger of hard frost has passed.
 
The soil temperature should be around 50°F or higher for the crowns to start growing actively.
 
Planting too late in spring stresses the crowns, and planting in fall usually gives them too little time to settle in before winter.
 

1. Dig a Trench About 12 Inches Wide

Dig a trench roughly 12 inches wide and 6 to 8 inches deep.
 
If you’re planting more than one row, space the rows about 4 to 5 feet apart.
 

2. Build Small Mounds in the Trench

Form a little mound of soil every 18 inches along the bottom of the trench.
 
Each crown gets its own mound.
 

3. Spread the Roots Over the Mound

Set the crown on top of the mound and spread its roots out evenly, like the legs of a spider.
 
The crown’s bud should sit about 2 inches below the soil surface.
 

4. Cover and Water Gently

Backfill with 2 to 3 inches of soil, then water it in well.
 
As the spears grow through the season, keep adding soil until the trench is filled.
 

Caring for Asparagus While It Establishes

Your first year of growing asparagus is all about letting the plants build strength, not about eating.
 
The ferns that grow above ground feed the crowns below, so they need to stay healthy all season.
 

1. Water Deeply but Not Too Often

Give the bed about an inch of water per week, including rainfall.
 
Deep watering encourages strong roots.
 

2. Keep Weeds Down

Weeds steal nutrients and water, and they’re much harder to remove once the ferns fill in.
 
Mulch around the plants to suppress them naturally.
 

3. Fertilize in Early Spring

Feed the bed each spring with compost or a balanced fertilizer.
 
Avoid high-nitrogen blends, which push leafy growth at the expense of strong roots.
 

4. Let the Ferns Die Back Naturally

In late fall, the ferns turn brown and die back on their own.
 
Cut them down to about 2 inches above the ground after they’ve fully browned.
 

When Can You Harvest Asparagus?

You can harvest asparagus spears in the third year after planting crowns, and sometimes a very light pick in the second year if the plants look vigorous.
 
In year one, don’t harvest at all.
 
In year two, take just a few spears from strong plants, and leave the rest to feed the roots.
 
By year three, you can cut spears for about four to six weeks each spring.
 
Snap or cut spears when they’re 6 to 8 inches tall and the tips are still tight.
 
Once the spears start opening into ferny branches, stop harvesting and let them grow.
 

Common Mistakes When Starting Asparagus

A few missteps can set your bed back years, so watch out for these.
 

1. Harvesting Too Soon

Cutting spears in year one weakens the crowns and can ruin the whole bed.
 

2. Planting in Wet Soil

Asparagus roots rot quickly in soggy ground, so drainage matters more than almost anything else.
 

3. Skipping Weed Control

Weeds compete hard with young asparagus and are tough to pull once the ferns mature.
 

4. Planting Too Shallow

Crowns set too close to the surface dry out and produce thin, weak spears.
 

So, How Do You Start Growing Asparagus?

You start growing asparagus by planting one-year-old crowns in early spring in a sunny, well-drained bed, then caring for the ferns and waiting two to three years before your first real harvest.
 
It’s a slow beginning, but the payoff is a bed that feeds you every spring for decades.
 
Pick the right spot, plant the crowns correctly, keep the weeds down, and be patient with those first few seasons.
 
Once your asparagus is established, you’ll wonder why you didn’t start growing it sooner.
