Yes, you can plant asparagus and rhubarb together, and they actually make one of the best perennial partnerships in a home garden.
Both are long-lived perennial crops that come back year after year, and they share similar soil and sunlight needs.
When you plant asparagus and rhubarb together, you create a low-maintenance garden bed that produces early spring harvests for decades.
In this post, we’ll look at why planting asparagus and rhubarb together works so well, how to set up the bed, and the common mistakes you’ll want to avoid.
Why You Can Plant Asparagus and Rhubarb Together
You can plant asparagus and rhubarb together because they’re both hardy perennials that thrive under almost the same conditions.
Here’s why this pairing works so well.
1. Both Are Long-Lived Perennials
Asparagus and rhubarb are two of the few vegetables that keep producing for 15 to 20 years or more.
That means when you plant asparagus and rhubarb together, you’re setting up a permanent bed rather than replanting every season.
Since neither crop needs to be rotated, planting asparagus and rhubarb together saves you space and effort in the long run.
2. They Share Similar Sun and Soil Needs
Both asparagus and rhubarb love full sun and well-drained, fertile soil rich in organic matter.
Asparagus sends down deep roots, and rhubarb develops thick, fleshy crowns, so neither one minds sharing a bed as long as the soil is loose and rich.
A slightly acidic to neutral soil pH between 6.0 and 7.0 keeps both crops happy when you grow asparagus and rhubarb together.
3. Their Harvest Seasons Overlap Nicely
Asparagus spears pop up in early spring, and rhubarb stalks are ready at almost the same time.
Planting asparagus and rhubarb together means you can walk out in spring and harvest both from the same bed.
They also complement each other in the kitchen, since rhubarb and asparagus both shine in spring recipes.
4. Asparagus Fills the Gap Above Rhubarb
Rhubarb grows low to the ground while asparagus ferns shoot up tall later in the season.
When you plant asparagus and rhubarb together, the asparagus can grow up and over without crowding the rhubarb crowns below.
Rhubarb leaves also help shade the soil, which keeps moisture in and weeds down around your asparagus.
How to Plant Asparagus and Rhubarb Together
Planting asparagus and rhubarb together takes a little planning up front, but it’s simple once the bed is ready.
1. Pick a Permanent Spot
Choose a sunny spot that won’t be disturbed for years, because both crops hate being moved.
Give each rhubarb crown about 3 feet of space and set asparagus crowns roughly 12 to 18 inches apart in rows.
Leave room between the two so the rhubarb’s large leaves don’t smother young asparagus spears.
2. Amend the Soil Deeply
Work in plenty of compost or aged manure before you plant asparagus and rhubarb together.
Both crops are heavy feeders, so rich soil gives them the nutrients they need to establish strong roots.
Good drainage matters too, since soggy soil rots both asparagus crowns and rhubarb roots.
3. Plant at the Right Depth
Set asparagus crowns in trenches about 6 to 8 inches deep and cover them gradually as they grow.
Plant rhubarb crowns so the buds sit just barely below the soil surface.
Getting the depth right when you plant asparagus and rhubarb together helps both crops settle in fast.
4. Water and Mulch Well
Keep the bed evenly moist during the first season, especially while roots are getting established.
A layer of mulch holds in moisture and keeps weeds from competing with your asparagus and rhubarb.
Just keep mulch a few inches away from rhubarb crowns so they don’t rot.
Common Mistakes When Planting Asparagus and Rhubarb Together
Even though planting asparagus and rhubarb together works well, a few missteps can set your bed back.
1. Harvesting Too Soon
Resist the urge to harvest asparagus spears or rhubarb stalks in the first year or two.
Both crops need time to build strong root systems before you start cutting.
Wait until the second or third year after you plant asparagus and rhubarb together to take a light harvest.
2. Letting Weeds Take Over
Young asparagus and rhubarb can’t compete with aggressive weeds.
Mulch heavily and hand-pull weeds instead of hoeing, which can damage shallow rhubarb roots.
A clean bed is one of the biggest keys to success when you plant asparagus and rhubarb together.
3. Skipping the Feedings
Both crops are hungry perennials that benefit from a yearly dose of compost or balanced fertilizer.
Feed in early spring before new growth appears so your asparagus and rhubarb start the season strong.
Skipping feedings leads to thin spears and small rhubarb stalks over time.
4. Poor Drainage
Standing water is the quickest way to kill a bed where you plant asparagus and rhubarb together.
If your soil stays soggy, build a raised bed to give both crops the drainage they need.
So, Can You Plant Asparagus and Rhubarb Together?
You can plant asparagus and rhubarb together, and the pairing works beautifully in a sunny, well-drained perennial bed.
Both crops love rich soil, full sun, and early spring harvests, so they’re natural companions.
Just give them space, amend the soil deeply, and be patient during those first couple of years.
Once your bed is established, planting asparagus and rhubarb together rewards you with fresh harvests for decades.
