To plant asparagus bare root, you simply need to dig a trench, create little mounds, and lay the roots over those mounds before covering them with soil.
It sounds a bit more involved than it actually is, but planting asparagus bare root is one of the most rewarding gardening projects you can take on.
If you’ve been wondering how to plant asparagus bare root and get those delicious spears for years to come, you’re in the right place.
In this post, we’ll walk through how to plant asparagus bare root step by step, talk about timing, soil prep, and the aftercare that turns those dry-looking roots into a thriving bed.
Let’s dig in.
How to Plant Asparagus Bare Root: Step by Step
Learning how to plant asparagus bare root is really about giving the crowns the best possible start in life.
Here’s the process broken down into simple steps.
1. Choose the Right Time to Plant Asparagus Bare Root
The best time to plant asparagus bare root is in early spring, as soon as the soil can be worked.
You can also plant asparagus bare root in late fall in milder climates, but spring gives the crowns a full season to establish.
When you plant asparagus bare root too late in spring, the crowns struggle to settle in before the summer heat hits.
So aim for cool, moist soil and a stretch of mild weather ahead.
2. Pick a Permanent Spot Before You Plant Asparagus Bare Root
Asparagus is a perennial, so wherever you plant asparagus bare root is where it will live for the next 15 to 20 years.
Choose a sunny spot with at least six to eight hours of direct light daily.
Make sure the area drains well, because soggy soil is the number one killer of asparagus crowns.
It also helps to clear out perennial weeds before you plant asparagus bare root, since you won’t be able to dig deep around the bed later.
3. Prepare the Soil
Before you plant asparagus bare root, work plenty of compost or aged manure into the top foot of soil.
Asparagus is a hungry feeder, so rich, loose soil gives those bare roots something to sink into.
A soil pH between 6.5 and 7.5 is ideal.
If your soil is heavy clay, mix in some sand or organic matter so the crowns don’t sit in water.
4. Dig the Trench
When you plant asparagus bare root, dig a trench about 12 inches wide and 6 to 8 inches deep.
If you’re planting more than one row, space the trenches about 4 feet apart.
As the plants grow, you’ll gradually fill the trench back in, so don’t worry about it looking deep at first.
5. Soak and Inspect the Bare Roots
Before you plant asparagus bare root, soak the crowns in a bucket of water for about an hour.
This rehydrates them after shipping and gives them a head start.
While they soak, toss out any roots that look mushy or dried to a crisp.
Healthy crowns should feel firm and have plenty of plump, spidery roots attached.
6. Form Mounds in the Trench
Inside your trench, shape little mounds of soil every 12 to 18 inches.
These mounds are where you’ll plant asparagus bare root crowns so the roots can drape naturally down the sides.
7. Place the Crowns on the Mounds
Set each crown on top of a mound and spread the roots out evenly around it.
When you plant asparagus bare root, the crown should sit right at or just below soil level.
If you bury the crown too deep, the spears struggle to push through.
8. Cover and Water
Cover the crowns with about 2 inches of soil and water gently.
As the shoots grow through the season, keep filling the trench until it’s level with the surrounding ground.
This gradual backfilling is one of the most important tricks when you plant asparagus bare root.
Caring for Your Asparagus After You Plant Asparagus Bare Root
Once you plant asparagus bare root, the real work of patience begins.
Keep the bed watered through dry spells, but never let it stay soggy.
Mulch around the plants to hold moisture and smother weeds.
Resist the urge to harvest during the first year, and only take a light harvest in the second.
By the third season, you can harvest fully for six to eight weeks each spring.
That long wait is the trade-off for a bed that keeps producing for decades.
Common Mistakes When You Plant Asparagus Bare Root
The biggest mistake is planting crowns too deep when you plant asparagus bare root.
Another is skipping the soak, which leaves the roots dry and slow to wake up.
Planting in a spot with poor drainage will rot the crowns before they ever sprout.
And harvesting too early weakens the plants just as they’re getting established.
Avoid these and your asparagus bed will reward you for years.
So, How Do You Plant Asparagus Bare Root?
To plant asparagus bare root, dig a trench, build small mounds, spread the roots over them, cover with soil, and water well.
The process is simple once you know the steps, and the payoff is a perennial harvest that keeps giving.
Pick the right spot, plant at the right time, and be patient for those first couple of years.
Once you plant asparagus bare root correctly, you’ll enjoy fresh spears every spring for a very long time.
