How to Grow Asparagus Plants


Hold on as we dive right into the universe of asparagus, a perennial favorite that promises a bountiful harvest for years to come. Imagine a single planting that can yield delicious spears for up to 15 years! Such longevity makes it essential to start off on the right foot.

The secret to a successful asparagus bed lies in the initial choice of location. This isn’t a crop for the fickle gardener; it requires a commitment to a sunny, well-drained spot that shuns the frosty pockets of your garden. Think of it as a long-term relationship with your soil. Choose wisely, and the asparagus will reward you with years of green, tender rewards.

So, let’s embark on this journey together, laying the groundwork for a thriving asparagus patch that stands the test of time. Stay tuned as we delve into the nitty-gritty of choosing the right variety, preparing your site, and nurturing these plants into their prime. With patience and care, you’ll be savoring the fruits of your labor, or in this case, the spears of your perseverance!

Choosing the Right Asparagus Variety

When it comes to asparagus, not all spears are created equal. The key to a bountiful asparagus bed is selecting the right variety that aligns with your climate and culinary expectations. Male asparagus plants, for instance, are the high achievers of the asparagus world. They don’t bother with seeds, focusing all their energy on producing larger, more succulent spears that keep coming back year after year. That’s why many gardeners lean towards all-male hybrid varieties like ‘Jersey Knight’ or ‘Jersey Giant’ for their robustness and productivity.

Cold hardiness is another crucial factor. Your asparagus plants will face winter year after year, and choosing a variety that can shrug off the cold is vital. If you’re gardening in a region with harsh winters, look for varieties known for their cold tolerance. On the other hand, open-pollinated varieties like ‘Mary Washington’ have their charm, offering a more traditional gardening experience, but they typically produce a mix of male and female plants, which can mean more maintenance and less yield. In the end, the right asparagus variety is the one that fits your garden’s climate and your appetite for garden-to-table freshness.

Preparing the Planting Site

When you’re ready to roll up your sleeves for asparagus, the magic begins with the soil. A pH sweet spot between 6.5 and 7.0 is where asparagus thrives, so don’t skip the soil test. It’s like a health check-up for your garden bed, revealing what nutrients are needed to welcome those asparagus crowns.

Now, picture your chosen spot basking in full sun, the soil rich and loamy, with water draining freely like a gentle stream. If you’re grappling with heavy clay, raise the stakes and the beds. Elevated rows will give your asparagus the drainage it craves and spare you the heartache of waterlogged roots.

The groundwork for asparagus success is a trench, about a shovel’s depth deep, cradling a layer of dehydrated cow manure or rich compost. This organic fare is the feast that fuels asparagus’s early growth, setting the stage for years of lush spears. Remember, asparagus is a long-term guest in your garden, so give it the space and care it deserves from the get-go. With the site prepped, you’re on the brink of an asparagus adventure that’s bound to be as rewarding as it is delicious.

Planting Asparagus Crowns and Seeds

When it comes to planting asparagus, you’ve got two routes: starting from seeds or planting crowns. Crowns, which are one-year-old roots, are your shortcut to an earlier harvest, slicing a year off the waiting time compared to seeds. If you’re eager to see those green spears poking through the soil sooner, crowns are the way to go. Picture yourself in 2-3 years, basking in the glory of your first harvest, while seeds will have you marking the calendar for about 4 years.

Dig a trench, and let’s get those crowns settled in their new home. They’re not fussy, but they do demand their space. Plant them about a foot and a half apart, in rows that are three to four feet apart, ensuring each crown’s bud faces skyward. Bury them gently, about 3 inches beneath the soil surface, tucking them in like precious treasures. Once planted, water them well to settle the soil and hydrate those thirsty roots. With the crowns snug in their beds, you’ve laid the foundation for asparagus success. Just imagine the day when you’ll be snapping off spears right from your backyard, all thanks to the care you’ve given today.

Caring for Asparagus Plants

As the asparagus plants take root, your care will guide them towards a verdant future. Ensuring the soil stays moist, especially after planting, is crucial for the development of strong roots and ferns. As the asparagus matures, regular watering becomes part of the rhythm of care, supporting the plants through their growth cycle.

Fertilization is a key post-harvest task, beginning in the third year. This is when the plants have established themselves and can handle the extra nutrients. A balanced fertilizer or well-aged compost works wonders, giving the asparagus the boost it needs to flourish next season. Mulching is another ally in your gardening arsenal, helping to keep those pesky weeds at bay and retaining soil moisture.

When winter whispers its approach, it’s time to prepare the asparagus bed for its slumber. Cutting the plants down to the ground before new growth starts ensures a clean slate for spring. And let’s not forget about the asparagus beetle, a common foe. Managing these pests is essential for maintaining healthy plants. A combination of vigilance and gentle, eco-friendly pest control can keep your asparagus bed thriving for years to come.

Harvesting Asparagus

Harvesting asparagus is a testament to your patience and care. After allowing the crowns to establish for 2-4 years without disturbance, the real reward begins. In the third year, those first spears will push through the soil, signaling it’s time to harvest.

Look for spears that stand 7-9 inches tall with a thickness akin to a pencil – these are prime for picking. Gently bend the spear near the base until it snaps, a natural breaking point that ensures the plant’s continued health and productivity.

Initially, the harvest period may last only a week or two, but as the plants mature, this window extends to four to six weeks in subsequent years, offering a more abundant crop. Remember, the goal is to harvest the spears before they start to fern out, capturing that tender, crisp texture.

With each passing year, your asparagus bed will become more prolific, a testament to the care you’ve invested in these perennial delights. So, when the time comes, enjoy the fruits of your labor, and know that with each spear you snap, you’re participating in a cycle of growth that’s been nurtured by your own hands.

Common Challenges and Solutions

Growing asparagus isn’t without its hurdles, but with a few clever strategies, you can leap over common challenges and land in a bed of lush green spears. One issue that might stump aspiring asparagus aficionados is the plant’s need for space due to its long root system. While keeping asparagus alive in pots is technically possible, these plants are like artists that need a wide canvas to truly flourish. They can feel stifled in pots, leading to less vigorous growth and a meager harvest. If you’re tight on space, consider asparagus varieties specifically bred for container life, but set expectations accordingly.

Another hiccup in the asparagus journey involves transplanting. These plants are homebodies at heart, preferring to stay put once they’ve settled in. However, if you must move them, timing is everything. The dormant period in early spring or the tranquil tail end of fall before the frost sets in is your window of opportunity. Carefully dig up the crowns, preserving as much of the root system as possible, and replant them promptly, minimizing the shock to their system. With these challenges navigated, your asparagus garden will be on the path to providing a bountiful harvest for years to come.


In the world of gardening, growing asparagus is akin to cultivating patience. It’s a plant that demands foresight and dedication, with a timeline stretching three to five years before you can truly reap what you sow. But oh, the rewards! A perennial vegetable that, once mature, offers over a month of tender, crisp spears each spring, asparagus is worth the wait.

Those who choose to embark on this green journey have the added delight of plucking fresh asparagus straight from the earth, a crunchy treat that needs no adornment. And for the gardeners who relish the process as much as the product, starting from seeds offers a full-circle experience.

As we wrap up this comprehensive guide, remember that asparagus isn’t just a plant; it’s a commitment to future feasts and the joy of watching something grow year after year. The key takeaway? Treat your asparagus with the care it deserves, and it will become a staple of your springtime table for many seasons to come.
