FAQs

What is the best time to harvest Autumn King 2?

The ideal harvest time is during September and October as a maincrop variety.

Can I grow these in containers?

Because the roots grow up to 30cm long, you would need a very deep container to support their growth.

How do I store them for winter?

Store in a cool, dry place away from direct sunlight, such as a garage or shed, ideally in boxes layered with slightly damp sand.

Do I need to fertilize the soil?

Avoid adding fresh manure immediately before sowing, as this can lead to forked roots; use a well-composted soil instead.

Is this an organic variety?

The seed itself is a traditional garden variety; standard organic gardening practices can be applied successfully to this crop.

Troubleshooting

Roots are stunted or forked

This is typically caused by stones or heavy debris in the soil; ensure the seedbed is finely raked and deeply cultivated before sowing.

Slow germination

Ensure the soil remains consistently moist and that the soil temperature is sufficiently warm; covering with horticultural fleece can help maintain warmth.

Carrot Fly damage

Use insect-proof mesh or horticultural fleece as a physical barrier to prevent the adult fly from laying eggs near the carrot base.

Pros and Cons

Pros

  • Excellent reliability even in challenging, heavy soils
  • High yield suitable for both home use and exhibition
  • Ideal for late-season harvesting and winter storage
  • Easy to grow for beginners and experienced gardeners alike

Cons

  • Requires significant vertical depth due to 30cm root length
  • Needs a full sun position for optimal growth
  • Longer maturity time compared to early-maturing varieties

Setup, Compatibility & Care

For the best results, sow seeds directly into a well-prepared seedbed that receives full sun. While this variety is tolerant of heavy soils, it is best practice to remove stones to prevent root forking. Space plants with a 15cm spread to allow adequate airflow and growth space. Keep the soil consistently moist during germination and the early growth stages. As a maincrop variety, it is generally resistant to standard garden pests if crop rotation is practiced. For storage, harvest the carrots carefully, allow them to air-dry briefly to remove excess moisture from the skin, and store them in a cool, dark, and ventilated location to prolong their shelf life through the winter months.
