Few garden investments match the return of a well-planted asparagus bed. Once established, Mary Washington crowns send up tender spears for two decades or more, making the initial choice of crown size and supplier the single most consequential decision a vegetable gardener makes. The difference between harvesting in year two versus waiting until year three comes down to whether you plant 2-year-old crowns or 1-year-old starts.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years comparing bare-root crown quality across suppliers, analyzing germination data from verified buyer reports, and cross-referencing zone-specific performance to identify which batches deliver on their genetic potential.
This guide breaks down the top contenders for the best mary washington asparagus plants, comparing crown age, root mass consistency, packaging protocols, and real-world sprout rates so you can plant with confidence.
How To Choose The Best Mary Washington Asparagus Plants
Mary Washington remains the most widely adapted heirloom asparagus variety because of its cold hardiness, disease resistance, and uniform spear production. But the nursery you choose and the crown age you buy matter more than the variety label itself. Here are the three factors that separate a thriving bed from a disappointing patch.
Crown Age: One-Year vs. Two-Year
A 1-year crown costs less but requires a full extra growing season before you can take a single harvest. Two-year crowns have a larger root mass and stored energy reserves, which means they establish faster, produce thicker spears sooner, and often fill the bed row more uniformly. For any gardener who values time over the initial price per crown, 2-year stock is the correct choice.
Root Condition at Arrival
Bare-root crowns are dormant but should still feel firm and show no signs of white mold or mushy tissue. Inspect the attachment point where the spear emerges — a healthy crown has a visible bud cluster. Dry, shriveled roots or a sour smell indicate improper storage or shipping delays. Reputable nurseries pack crowns with a moisture-retaining medium and include planting instructions that address your specific hardiness zone.
Soil Compatibility and Preparation
Mary Washington demands well-draining soil. Several suppliers explicitly warn that heavy clay without sand amendment leads to root rot. If your native soil holds water, budget for adding 30% coarse sand per crown and plan to plant on a slight mound or in a raised trench. The deeper you plant — 8 to 12 inches depending on latitude — the better the winter protection for the crown.

In‑Depth Reviews
1. Hand Picked Nursery Mary Washington Asparagus Bare Root Plants – 25 Crowns
This is the largest 2-year-old crown pack from a veteran family-run nursery with over 15 years of operation. Every single crown in this 25-pack has the genetic maturity to produce harvestable spears by the second season, provided the buyer follows the explicit sand-mix planting instructions. Multiple verified buyers reported visible sprout activity within 10 days and crowns arriving in firm, healthy condition — a direct result of the nursery’s careful moisture management during shipping.
The supplier emphasizes that 30% sand by volume must be mixed into the soil to prevent crown rot, a detail that appears repeatedly in the instructions. Customers who followed this protocol in zones as varied as Colorado and Florida reported near-100% germination. A small number of reviews noted size inconsistency among the 25 crowns, with roughly half being extremely vigorous and the remainder more typical of 1-year stock, but all arrived alive and grew after planting.
One recurring concern was the use of plastic bags for shipping, which in a few cases led to minor mold on the outer roots. The nursery includes free plant-boost fertilizer with each order and offers phone support for troubleshooting. For gardeners who want to maximize bed density with a single order and don’t mind a brief inspection upon arrival, this pack delivers the best crown-to-dollar ratio of mature stock available.
What works
- All 2-year crowns, giving a full-season head start on harvest
- Included plant boost and detailed sand-drainage instructions
- Excellent sprout rate reported across diverse hardiness zones
What doesn’t
- Plastic bag packaging can trap moisture and cause minor mold
- Crown size varies within the pack, with some roots being noticeably smaller
2. Garden State Bulb Mary Washington Asparagus Bare Root Crowns – Bag of 20
Garden State Bulb brings a polished presentation and a 1-year limited replacement guarantee to its bare-root crowns. The 20-count bag arrives in temperature-controlled packaging with printed planting instructions and a QR code linking to a video tutorial — ideal for the beginner who wants clear guidance. These are 1-year crowns, so expect a slower path to full production, but the disease-resistant genetics and heat tolerance make this a strong choice for southern growers in zones 2 through 9.
Buyers consistently praised the firm, healthy knots on the roots and the timely delivery. A notable pattern in the reviews is that the pack often contains 22 or 23 crowns instead of the advertised 20, which compensates for any that fail to sprout. The moisture needs are listed as regular watering with full sun, and the expected maturity height of 24 to 36 inches matches the classic Mary Washington profile for heavy, uniform spears.
The main drawback is the one-year head start you forfeit with 1-year stock. Several verified reviewers noted that after the first growing season only 12 to 15 of the 20 crowns had sprouted, with the smaller roots failing to push through. This is not unusual for 1-year crowns, but it means the bed will take an extra season to fill in completely. For patient gardeners who value company backing and genetic purity over immediate density, this is a solid mid-range option.
What works
- Professionally packed with full planting instructions and video support
- 1-year replacement guarantee from a major bulb supplier
- Non-GMO, disease-resistant, and heat-tolerant genetics
What doesn’t
- 1-year crowns require an extra season before harvestable spears appear
- Smaller roots in the pack often fail to sprout, reducing effective count
3. JW Farms Mary Washington Asparagus Roots/Plants – 25 Crowns
JW Farms offers the lowest per-crown price among the 25-count options, making this the obvious pick for anyone establishing a large bed on a budget. These are second-year crowns, and multiple buyers reported receiving 28 to 30 roots instead of the advertised 25, with most being large and healthy. One verified buyer planted on June 16 and observed visible rows of growth by June 25 after incorporating blood meal and bone meal into the trench.
The feedback is consistent that these crowns shoot up quickly once planted, with many reviews using the phrase “growing like weeds.” The low maintenance requirement is frequently mentioned — native soil with compost and sand seems sufficient. The supplier does not include a detailed planting guide, so first-time growers will need to research trench depth and spacing separately.
The most significant risk is inconsistency: a small but notable number of buyers reported zero growth from the entire pack, with one reviewer stating that a bed from a different supplier performed well while the JW Farms batch failed completely. This could indicate occasional quality-control issues at the packaging stage. Given the low per-crown cost, ordering two packs and culling the weakest roots before planting is a reasonable hedge.
What works
- Exceptional per-crown value, often shipping bonus roots beyond the advertised count
- Fast sprouting, with visible growth reported within 7 to 10 days
- Performs well with basic native soil and compost
What doesn’t
- No printed planting instructions included in the package
- Inconsistent batches — some packs produce zero growth
4. CZ Grain Mary Washington Live Asparagus Bare Root Plants – 20 Crowns
CZ Grain markets this 20-crown pack as a DIY gift item, but the product itself is a straightforward 2-year-old Mary Washington bare-root set. Verified buyers noted that the crowns arrived dormant but already showing tiny sprout tips, indicating proper cold storage timing.
The sprouting speed impressed many growers, with one buyer reporting visible growth within three days of planting. The instructions are accessible via a video link tutorial, which covers trench depth and spacing for different zones. Crowns are listed as suitable for both full sun and partial shade, which is unusual for asparagus — most suppliers require full sun — but this may simply reflect the product’s broad labeling for indoor/outdoor use.
The most serious complaint comes from a buyer who received shriveled, mold-covered crowns after a 7-day shipping delay; those crowns produced zero growth after a month. This suggests that CZ Grain’s packaging may be less robust than dedicated nurseries, and shipping duration is a risk factor. For budget-conscious growers who can plant immediately upon arrival and inspect each crown before placing it in the trench, this pack delivers solid genetics at the lowest sticker price.
What works
- Lowest entry price for 2-year-old Mary Washington crowns
- Fast sprout response, often visible within days of planting
- Video tutorial included for first-time asparagus growers
What doesn’t
- Packaging less moisture-protected than specialty nurseries
- Risk of mold and desiccation with extended shipping times
5. Hand Picked Nursery Mary Washington Asparagus Bare Root Plants – 10 Crowns
The smaller sibling to Hand Picked Nursery’s 25-pack, this 10-crown option serves the same 2-year-old heirloom stock at a lower total investment. It is the ideal choice for a small-space gardener, a test bed before expanding, or a container grower who can provide a deep enough pot. The free plant boost fertilizer and the nursery’s reputation for responsive customer support carry over from the larger pack.
Buyer experiences align closely with the 25-pack: healthy crowns that sprout within days when the 30% sand requirement is met. One verified buyer in zone 9A Florida used the trench method at 8 to 10 inches deep with topsoil, manure, and perlite, achieving 3- to 4-inch spears within four days and 100% germination. Another buyer at 7,400 feet in Colorado reported all crowns sprouting well despite a second order that arrived with minor mold.
The trade-off is the per-crown price, which is higher than the 25-pack for the same stock. The 10-pack also suffers from the same plastic-bag packaging issue, which can cause condensation in transit. A handful of buyers reported that 3 to 4 of the 10 crowns did not sprout, consistent with a typical failure rate for bare-root crops. For a small bed, ordering two packs to compensate for potential losses while still staying within a modest budget is a practical approach.
What works
- Same high-quality 2-year crowns as the larger pack, ideal for small spaces
- Excellent sprout rates when sand-drainage instructions are followed
- Responsive customer support and free plant boost included
What doesn’t
- Higher per-crown price compared to the 25-count pack
- Plastic bag packaging risks trapped moisture and mold in transit
Hardware & Specs Guide
Crown Age and Dormancy
A 2-year crown has a root mass roughly twice the diameter of a 1-year crown, with visible bud clusters that indicate stored energy. Dormant crowns should feel firm, not mushy, and show no white or green fuzz. Inspect the attachment point where the previous year’s spear emerged — a healthy crown has a dry, woody scar, not a wet one. If a crown arrives with active green shoots, plant it immediately, as the nursery has broken dormancy prematurely.
Trench Depth and Spacing
Mary Washington performs best when planted 8 to 12 inches deep in a V-shaped trench, with the crown placed on a small mound of soil mixed with 30% coarse sand. Space crowns 12 to 18 inches apart within the row, with rows 3 to 4 feet apart. Fill the trench gradually as the spears grow, leaving 2 inches of the spear exposed each time until the trench is level. This method encourages a deep, cold-hardy root system that survives northern winters.
