Yes, you can plant asparagus and rhubarb together, and it’s actually one of the smartest pairings you can make in a perennial vegetable garden.
Both are long-lived crops that come back year after year, so they share a similar rhythm once they’re established.
If you’ve been wondering whether you can plant asparagus and rhubarb together, the short answer is a resounding yes.
They enjoy similar soil conditions, they both love a sunny spot, and they can live side by side for decades without competing for space.
In this post, we’ll walk through why asparagus and rhubarb grow so well together, how to plant them properly, and the few things you need to watch out for.
Let’s dig in.
Why You Can Plant Asparagus and Rhubarb Together
You can plant asparagus and rhubarb together because they’re both hardy perennials that thrive under nearly identical growing conditions.
Here’s why this pairing works so well:
1. They Share the Same Soil Preferences
Asparagus and rhubarb both love well-drained, fertile soil rich in organic matter.
Neither one enjoys sitting in soggy ground, so if you amend your bed with compost and ensure good drainage, both plants will be happy.
A slightly acidic to neutral pH between 6.0 and 7.0 suits both crops perfectly.
2. They Have Similar Sun and Water Needs
Both asparagus and rhubarb need full sun to produce well.
They also appreciate consistent moisture without being waterlogged.
So when you plant asparagus and rhubarb together, you can water the entire bed on the same schedule.
3. They’re Both Long-Term Investments
These aren’t crops you replant every year.
When you plant asparagus and rhubarb together, you’re setting up a bed that can keep producing for 15 to 20 years or more.
That means you only need to prepare the site once and then reap the harvest for decades.
4. Their Growing Habits Complement Each Other
Asparagus sends up tall, ferny spears while rhubarb spreads out with large, bold leaves.
The two plants occupy slightly different zones, so they don’t crowd each other out.
This makes planting asparagus and rhubarb together a natural fit in a mixed perennial bed.
How to Plant Asparagus and Rhubarb Together
Planting asparagus and rhubarb together takes a bit of planning, but it’s not complicated.
Here’s how to get it right:
1. Pick the Right Spot
Choose a sunny location that gets at least six to eight hours of direct light each day.
Make sure the area drains well because neither asparagus nor rhubarb tolerates wet feet.
2. Prepare the Soil Deeply
Dig in plenty of compost or aged manure before planting.
Asparagus roots go deep, so loosening the soil at least 12 inches down gives them room to spread.
Rhubarb also benefits from that rich, loose soil.
3. Give Each Plant Enough Space
Space rhubarb crowns about 3 to 4 feet apart since they grow large.
Plant asparagus crowns about 12 to 18 inches apart in rows or beds.
When you plant asparagus and rhubarb together, leave a little buffer between them so each has room to expand.
4. Plant at the Right Depth
Set asparagus crowns in trenches about 6 to 8 inches deep, covering them gradually as they grow.
Plant rhubarb crowns so the buds sit just at or slightly below the soil surface.
Getting the depth right when you plant asparagus and rhubarb together helps both establish strong root systems.
Things to Watch Out For When You Plant Asparagus and Rhubarb Together
Even though these two make great companions, there are a few things to keep in mind.
1. Rhubarb Leaves Are Toxic
Rhubarb leaves contain oxalic acid, which is toxic to humans and pets if eaten.
But they’re perfectly safe to add to the compost pile.
2. Asparagus Needs Patience
Don’t harvest asparagus spears for the first two or three years after planting.
Let the ferns grow so the crowns build up energy.
Once you plant asparagus and rhubarb together, expect to wait a bit before your first real harvest.
3. Avoid Overcrowding
Rhubarb can get huge, so don’t plant it too close to your asparagus rows.
Give the rhubarb plenty of elbow room so it doesn’t shade out the asparagus spears.
4. Keep Weeds Down
Both crops dislike weed competition, especially while they’re getting established.
Mulch around the plants to suppress weeds and retain moisture.
5. Watch for Pests
Asparagus beetles and rhubarb curculios can show up.
Check your plants regularly and remove any pests you spot.
So, Can You Plant Asparagus and Rhubarb Together?
You can plant asparagus and rhubarb together, and doing so creates a productive, low-maintenance perennial bed that keeps giving for years.
Both crops love the same soil, sun, and water conditions, so they make natural garden companions.
Just give them space, plant them at the right depth, and be patient during those first couple of seasons.
Once established, your asparagus and rhubarb bed will reward you with fresh harvests season after season.
Whether you’re a seasoned gardener or just starting out, learning that you can plant asparagus and rhubarb together opens up a smart way to grow more food with less effort.
