Yes, rhubarb can be planted next to asparagus, and this pairing can actually work quite well in a home garden.
Both are perennial vegetables that come back year after year, so once you get them established, you’ll have a reliable harvest without replanting.
If you’ve been wondering whether rhubarb can be planted next to asparagus, the short answer is yes, as long as you give each plant the space and conditions it needs to thrive.
They have different soil preferences, but those differences can be managed with a little planning.
In this post, we’ll look at why rhubarb can be planted next to asparagus, the best way to set up the bed, and a few mistakes to avoid.
Let’s dig in.
Why Rhubarb Can Be Planted Next To Asparagus
Rhubarb can be planted next to asparagus, and here’s why this combo makes sense:
1. Both Are Long-Lived Perennials
Asparagus and rhubarb are two of the few vegetables that stay put for years.
Asparagus can produce for 15 to 20 years, while rhubarb often lasts a decade or more with proper care.
Because they share a similar lifespan, you won’t have to dig up one crop to replant the other.
That makes rhubarb planted next to asparagus a smart, low-maintenance pairing for a permanent bed.
2. They Occupy Different Garden Layers
Asparagus grows tall, ferny spears that reach up to five or six feet.
Rhubarb stays lower with big, broad leaves that spread about three to four feet wide.
Since asparagus grows upward and rhubarb spreads outward, they don’t compete for the same vertical space.
You can plant rhubarb next to asparagus without one smothering the other.
3. Compatible Sunlight Needs
Both plants love full sun, needing at least six to eight hours a day.
That shared love of sunlight means you can plant them in the same sunny spot without worrying about one getting too much light.
When rhubarb is planted next to asparagus, both get the bright exposure they crave.
4. Different Harvest Windows
Asparagus is harvested in spring, usually from April to June.
Rhubarb is also harvested in spring, but its stalks can be picked from late spring into early summer.
Because their peak harvest times overlap only slightly, you won’t be fighting to harvest both at once.
This staggered timing is another reason rhubarb can be planted next to asparagus.
How To Plant Rhubarb Next To Asparagus
Getting the spacing and soil right is key when you plant rhubarb next to asparagus.
1. Give Them Plenty Of Space
Asparagus crowns should be spaced about 12 to 18 inches apart in rows that are three to four feet apart.
Rhubarb needs even more room, with each plant spaced three to four feet from its neighbor.
When you plant rhubarb next to asparagus, leave at least three feet between the rhubarb crown and the asparagus row.
That gap keeps roots from tangling and gives each plant room to grow.
2. Prepare The Soil Carefully
Asparagus likes well-drained, sandy loam with a pH around 6.5 to 7.0.
Rhubarb prefers rich, loamy soil with a pH between 6.0 and 6.8.
The overlap is close enough that you can plant rhubarb next to asparagus in a bed with a pH near 6.5.
Work in plenty of compost before planting to keep both crops happy.
3. Plant At The Right Depth
Asparagus crowns go about six to eight inches deep in a trench.
Rhubarb crowns should sit just below the soil surface, with the buds barely covered.
Planting rhubarb next to asparagus means digging two different depths in the same bed, so mark your rows before you start.
4. Water And Mulch Well
Both plants need consistent moisture, especially in their first year.
Water deeply once a week, and add a two-inch layer of mulch to hold in moisture and keep weeds down.
Mulching also helps when rhubarb is planted next to asparagus because it keeps the soil cool and steady.
Potential Problems To Watch For
Even though rhubarb can be planted next to asparagus, a few issues can pop up.
1. Rhubarb Leaves Can Shade Asparagus
Rhubarb leaves get huge and can block sunlight from young asparagus spears.
Keep rhubarb on the north or east side of your asparagus rows so the tall ferns still get full sun.
2. Different Water Needs In Wet Years
Asparagus hates soggy roots, while rhubarb is a bit more tolerant of moisture.
If your soil drains poorly, plant rhubarb next to asparagus on a raised bed to keep both from rotting.
3. Competing For Nutrients
Both are heavy feeders and will pull nutrients from the same soil.
Side-dress with compost or a balanced organic fertilizer each spring to keep them thriving.
So, Can Rhubarb Be Planted Next To Asparagus?
Rhubarb can be planted next to asparagus, and the two make a great long-term pairing in a perennial garden.
They share a love of sun, live for years, and grow in different layers so they don’t crowd each other out.
Just give them enough space, prepare the soil well, and keep an eye on water and nutrients.
If you’ve been asking whether rhubarb can be planted next to asparagus, now you know the answer is a confident yes.
Happy planting.
