Can You Regrow Store Bought Asparagus

Yes, you can regrow store bought asparagus, but it comes with a few important caveats that every curious gardener should know.
 
The crowns you buy at the grocery store are usually harvested for eating, not replanting, so what you’re working with is a little different from seed or nursery crowns.
 
Still, if you’ve ever wondered can you regrow store bought asparagus, the short answer is yes, though the process takes patience and a bit of know-how.
 
In this post, we’ll walk through whether you can regrow store bought asparagus, how to do it the right way, and what results you can realistically expect.
 
Let’s dig in.
 

Can You Regrow Store Bought Asparagus and How Does It Work?

You can regrow store bought asparagus, but understanding how asparagus grows will help you set realistic expectations.
 
Unlike lettuce or green onions that regrow from a simple cutting in water, asparagus is a perennial that grows from a crown.
 
When you regrow store bought asparagus, you’re essentially trying to convince a harvested spear or crown to start a whole new life.
 
Here’s how that breaks down.
 

1. Asparagus Grows From Crowns, Not Just Spears

Asparagus spears are the young shoots that emerge from an underground crown.
 
When you buy asparagus at the store, you’re usually buying those harvested spears, which have been cut from the crown.
 
If you want to regrow store bought asparagus from spears, you’ll need to root them, which is tricky.
 
If you can find store bought crowns, your chances of regrowing store bought asparagus go up dramatically.
 

2. Spears Can Root, But It’s Hit or Miss

Yes, you can attempt to regrow store bought asparagus from the spears themselves.
 
The bottom of the spear needs to be fresh, firm, and hydrated.
 
You place the cut end in water or a moist growing medium and wait for roots to form.
 
This method of regrowing store bought asparagus sometimes works, but many spears simply rot before rooting.
 

3. Crowns Give You the Best Shot

If you really want to regrow store bought asparagus successfully, look for crowns sold in garden centers or online.
 
These are one-year-old roots ready to plant.
 
Some grocery stores even sell potted asparagus crowns in spring.
 
When you regrow store bought asparagus from a crown, you’re giving the plant a proper head start.
 

4. Patience Is Non-Negotiable

Even when you regrow store bought asparagus successfully, you won’t harvest spears for at least two to three years.
 
The first year, you let the plant grow into ferny stalks to build energy.
 
The second year, you might snag a spear or two.
 
By year three, your regrown store bought asparagus can finally produce a real harvest.
 

How to Regrow Store Bought Asparagus Step by Step

If you’re ready to try regrowing store bought asparagus, here’s a simple method that gives you the best odds.
 

1. Start With Fresh, Healthy Spears or Crowns

For spears, choose thick, firm stalks with tight tips and no mushiness.
 
For crowns, pick ones that feel heavy and show no signs of mold.
 
The healthier your starting material, the better your chances when you regrow store bought asparagus.
 

2. Trim and Hydrate the Spear Ends

Cut about an inch off the bottom of each spear at a slight angle.
 
Place the cut ends in a glass of fresh water, just like you’d do with flowers.
 
Change the water every couple of days to keep it clean.
 
This step is crucial when you regrow store bought asparagus from spears.
 

3. Wait for Roots, Then Pot Them Up

After a week or two, you may see tiny white roots forming.
 
Once roots reach an inch or two, transfer the spears into pots filled with potting mix.
 
Keep the soil moist but not soggy.
 
This is the moment your regrow store bought asparagus project starts to feel real.
 

4. Plant Crowns Directly in Rich Soil

If you’re using crowns, plant them in a trench about six inches deep.
 
Space them a foot apart and cover with soil gradually as they grow.
 
Full sun and well-drained soil are must-haves.
 
When you regrow store bought asparagus from crowns, this step sets the stage for years of production.
 

5. Care for Them Like Any Asparagus Patch

Water regularly, mulch to control weeds, and fertilize in early spring.
 
Let the ferns grow tall and brown before cutting them back in late fall.
 
Your regrow store bought asparagus bed will reward you if you treat it like a long-term investment.
 

Common Mistakes When You Regrow Store Bought Asparagus

Even with the best intentions, people run into trouble when they regrow store bought asparagus.
 

1. Using Old or Soft Spears

Spears that have been sitting in the fridge for weeks are unlikely to root.
 
The fresher the spear, the better your odds when you regrow store bought asparagus.
 

2. Keeping Them in Water Too Long

Roots need oxygen, and sitting in stale water can cause rot.
 
Transfer to soil as soon as roots appear.
 
This mistake kills more regrow store bought asparagus attempts than anything else.
 

3. Harvesting Too Soon

It’s tempting to snip a spear the first year.
 
Don’t.
 
When you regrow store bought asparagus, the plant needs every bit of energy to establish roots and crowns.
 

4. Planting in Poorly Drained Soil

Asparagus hates wet feet.
 
If your soil stays soggy, the crowns will rot.
 
Raised beds or amended soil give your regrow store bought asparagus the drainage it craves.
 

So, Can You Regrow Store Bought Asparagus?

Yes, you can regrow store bought asparagus, and it can be a fun and rewarding experiment.
 
The key is knowing whether you’re starting with spears or crowns, because crowns give you the best chance.
 
When you regrow store bought asparagus from spears, expect mixed results and be patient.
 
When you regrow store bought asparagus from crowns, you’re setting yourself up for a productive patch in a few years.
 
Either way, regrowing store bought asparagus teaches you a lot about how this amazing perennial grows.
 
So give it a try, keep your expectations realistic, and enjoy the journey of regrowing store bought asparagus.
