Yes, you can plant different types of asparagus together, and many gardeners do it successfully every season.
Asparagus is a perennial vegetable, so once you plant different types of asparagus together, they’ll share the same bed for years.
The key is understanding how each type grows so your asparagus types don’t compete in ways that hurt your harvest.
In this post, we’ll look at what happens when you plant different types of asparagus together and how to do it right.
Let’s dig in.
Can You Plant Different Types of Asparagus Together?
You can plant different types of asparagus together, but there are a few important things to keep in mind.
Asparagus comes in three main categories: all-male hybrids, open-pollinated varieties, and heirloom types.
Each type has its own growth habits, disease resistance, and harvest timing.
When you plant different types of asparagus together, those differences can either work in your favor or create a few headaches.
1. Male and Female Plants Behave Differently
Some asparagus varieties produce mostly male plants, while others produce a mix of male and female plants.
Male asparagus plants put more energy into spears because they don’t waste resources on seeds.
Female plants produce berries and seeds, which can lead to volunteer asparagus seedlings popping up around your bed.
If you plant different types of asparagus together, the female plants may cross-pollinate with other varieties.
That cross-pollination doesn’t hurt the spears you eat, but it can create unpredictable seedlings.
2. Different Types Mature at Different Times
When you plant different types of asparagus together, you’ll notice they don’t all send up spears at the same time.
Early varieties like Purple Passion tend to emerge sooner in spring.
Later varieties like Mary Washington might wait another week or two.
That staggered harvest can be a good thing because you get fresh asparagus over a longer window.
Just don’t expect every type of asparagus to be ready on the same day.
3. Disease Resistance Varies by Variety
One of the biggest reasons to think twice before you plant different types of asparagus together is disease.
Some asparagus varieties resist rust and fusarium wilt better than others.
If you mix a resistant type of asparagus with a susceptible one, the weaker plant can spread problems.
Asparagus beds last 15 to 20 years, so a disease issue doesn’t go away quickly.
That’s why many growers plant different types of asparagus together only when all varieties share strong disease resistance.
Benefits of Planting Different Types of Asparagus Together
Even with the challenges, there are real benefits when you plant different types of asparagus together.
Here’s why some gardeners do it on purpose.
1. Longer Harvest Season
If you plant different types of asparagus together, you can stretch your harvest from early spring into early summer.
Early varieties give you the first spears, and late varieties keep producing after the early ones slow down.
That means more fresh asparagus for your table without planting a second bed.
2. Better Pollination and Genetic Diversity
When you plant different types of asparagus together, you increase genetic diversity in your bed.
That diversity can help your asparagus adapt to local soil and weather over time.
It won’t change the flavor of your spears, but it can make your bed more resilient.
3. Visual Interest in the Garden
Different types of asparagus come in different colors.
Purple asparagus, green asparagus, and even white asparagus can all grow side by side.
If you plant different types of asparagus together, your bed becomes a pretty mix of colors and textures.
That’s a nice bonus for a perennial bed you’ll look at for decades.
How to Plant Different Types of Asparagus Together the Right Way
If you decide to plant different types of asparagus together, follow these steps for the best results.
1. Choose Varieties with Similar Disease Resistance
Pick asparagus types that all resist rust and fusarium wilt.
That way, when you plant different types of asparagus together, no single variety becomes the weak link.
2. Group Them in Blocks, Not Rows
Instead of alternating plants, plant each type of asparagus in its own block within the bed.
That makes it easier to manage harvest timing and disease control when you plant different types of asparagus together.
3. Give Them Plenty of Space
Asparagus roots spread wide, so each crown needs about 12 to 18 inches of space.
If you crowd them when you plant different types of asparagus together, the roots will compete for water and nutrients.
4. Keep the Soil Consistent
All asparagus types want well-drained soil with a pH between 6.5 and 7.5.
If you plant different types of asparagus together, don’t let one section dry out while another stays soggy.
So, Can You Plant Different Types of Asparagus Together?
You can plant different types of asparagus together, and it often works well when you choose compatible varieties.
The biggest risks are disease spread and cross-pollination from female plants.
But if you pick resistant types of asparagus, group them in blocks, and give them room to grow, you can plant different types of asparagus together successfully.
Just remember that an asparagus bed is a long-term commitment, so plan carefully before you plant different types of asparagus together.
With the right approach, your mixed asparagus bed can give you a longer harvest and a more interesting garden for years to come.
