Yes, you can replant asparagus stalks, but it’s a bit more nuanced than just sticking a stalk back into the ground.
The stalks you see above ground are actually the spears, and the real magic happens underground with the crowns.
If you’re asking yourself, “Can you replant asparagus stalks?” the short answer is yes, but you’ll need to replant the crowns for them to grow into new plants.
In this post, we’ll cover whether you can replant asparagus stalks, how to do it properly, and what to expect from your asparagus bed.
Can You Replant Asparagus Stalks? Here’s What Actually Works
You can replant asparagus stalks, but the key is understanding what part of the plant you’re actually replanting.
The stalks themselves won’t grow into new plants if you just cut them and stick them in the soil.
Instead, you need to replant the crowns, which are the fleshy root systems that produce those tasty stalks.
Here’s why this matters:
1. Asparagus Stalks Are Just the Above-Ground Growth
The stalks you harvest and eat are the spears that emerge from the crown each spring.
These spears are designed to photosynthesize and feed the crown, not to reproduce on their own.
If you cut a stalk and replant it, it won’t have the root system needed to survive and grow.
That’s why replanting asparagus stalks alone doesn’t work the way you might hope.
2. The Crowns Are the Real Deal for Replanting
When you replant asparagus, you’re actually replanting the crowns.
The crowns are the underground structures that store energy and send up new spears every year.
You can dig up established crowns and replant them in a new location, and they’ll continue producing stalks.
So if you want to replant asparagus stalks successfully, focus on the crowns.
3. You Can Replant Asparagus from Seed Too
Another way to replant asparagus is by starting from seed.
It takes longer, usually three years before you can harvest, but it’s a viable option.
You plant the seeds, let them grow into crowns, and then those crowns produce the stalks you’ll eventually harvest.
So while you can’t replant asparagus stalks directly, you can replant the crowns or start fresh with seeds.
How to Replant Asparagus Crowns Successfully
If you want to replant asparagus crowns, here’s how to do it right.
1. Choose the Right Time to Replant
The best time to replant asparagus is in early spring or late fall when the plant is dormant.
If you replant during the growing season, you risk shocking the plant and killing it.
Wait until the stalks have died back and the crown is resting before you dig it up.
2. Prepare the Soil Properly
Asparagus loves well-drained soil with plenty of organic matter.
Before you replant asparagus crowns, work in compost or aged manure to give them a nutrient-rich start.
The soil should be loose and not waterlogged, as soggy conditions can rot the crowns.
3. Dig and Replant Carefully
When you replant asparagus crowns, dig a trench about 6 to 8 inches deep.
Place the crowns in the trench with the roots spread out and the buds facing up.
Cover them with a few inches of soil, and gradually fill the trench as the stalks grow.
This helps the plant establish a strong root system.
Can You Replant Asparagus Stalks from the Grocery Store?
A common question is whether you can replant asparagus stalks from the grocery store.
The answer is no, those stalks won’t grow into new plants.
They’ve been harvested and chilled, and they don’t have the crown or root system needed to survive.
If you want to replant asparagus, you’ll need to start with crowns or seeds from a garden center.
Common Mistakes When You Replant Asparagus
Even when you replant asparagus crowns, things can go wrong.
Here are a few mistakes to avoid:
1. Planting Too Deep or Too Shallow
If you replant asparagus too deep, the stalks will struggle to reach the surface.
Too shallow, and the crowns may dry out or freeze in winter.
Aim for 6 to 8 inches deep for the best results.
2. Not Giving Them Enough Space
Asparagus needs room to spread its roots.
When you replant asparagus crowns, space them about 12 to 18 inches apart.
Crowded crowns compete for nutrients and produce thinner stalks.
3. Harvesting Too Soon
After you replant asparagus, resist the urge to harvest for at least a year.
The plant needs time to establish itself and build up energy reserves.
Harvest lightly the second year, and then go full throttle the third year.
So, Can You Replant Asparagus Stalks?
You can replant asparagus stalks, but not in the way you might think.
The stalks themselves won’t grow into new plants, but the crowns will.
If you want to replant asparagus, dig up the crowns in early spring or late fall, prepare the soil well, and give them space to thrive.
With a little patience, you’ll be harvesting fresh asparagus from your replanted crowns for years to come.
