Product Information

Full details

The Carbeth Plants Asparagus Boonlim Crowns are designed for home gardeners and allotment enthusiasts looking to establish a high-yield, long-term perennial vegetable patch. These premium crowns provide a significant head start over seed-grown plants, offering robust growth and earlier harvests of thick, sweet spears. While they promise 10 to 20 years of productivity, gardeners must be prepared for a mandatory one-year establishment period where no harvesting is permitted to allow the root system to fully mature.

FAQs

When is the best time to plant these crowns?

Planting should occur in early spring as soon as the soil has warmed up and is easy to dig.

Can I harvest in the first year?

No, it is essential to avoid harvesting in the first year to allow the plant to focus all its energy on establishing a strong root system.

How deep should I plant the crowns?

Place the crowns in a trench approximately 20-30cm deep, spreading the roots out over a small mound of soil at the base of the trench.

Do I need to fertilize my asparagus?

Yes, annual applications of well-rotted manure or organic compost in early spring will maintain the soil fertility necessary for long-term yields.

How long will the bed last?

With proper care and soil maintenance, an asparagus bed can remain productive for 10 to 20 years.

How much sun do they need?

Asparagus thrives in full sun and requires at least 6-8 hours of direct sunlight per day.

Troubleshooting

Slow initial growth after planting

Ensure the crowns were planted in full sun and check that the soil is not waterlogged. Add organic matter to improve aeration.

Yellowing foliage mid-summer

This may indicate overwatering or poor drainage. Monitor soil moisture and ensure the bed is not situated in a low spot where water collects.

Thin, weak spears

Ensure the plant is fully established (typically requires two years). If mature, provide a balanced organic fertilizer during the early spring growth flush.

Pros and Cons

Pros

  • Significantly faster harvest than growing from seed
  • High disease resistance for easier maintenance
  • Reliable production for up to two decades
  • Produces premium, thick, and sweet spear quality

Cons

  • Requires a full year of growth without harvest to establish roots
  • Needs specific, well-drained soil conditions for optimal success
  • Initial planting requires significant space and soil preparation

Setup, Compatibility & Care

For optimal results, plant your crowns in a sunny location that receives at least six to eight hours of direct light daily. Soil must be well-draining, as standing water can cause root rot; if your soil is heavy clay, consider using raised beds to improve drainage. Add plenty of well-rotted manure or compost before planting to provide the nutrient density required for long-term health. Keep the area free of weeds throughout the growing season, as asparagus does not compete well with invasive grasses. Apply a light mulch around the base of the plants to retain moisture and suppress weeds. In late autumn, once the foliage has turned yellow or brown, cut the stems back to ground level to prepare for winter dormancy.
