How to Grow Onion Ailsa Craig Seeds: Your Step-by-Step Guide

Beginning Your Onion Adventure

If you’re looking to add a versatile crop to your garden, onions are an excellent choice. With Onion Ailsa Craig Seeds, you can expect large, globe-shaped bulbs perfect for early winter consumption.

When and Where to Sow

For early sowing, aim for December to April and sow under glass. Alternatively, if you’re looking for smaller onions, outdoor sowing can be done in April. Here are some quick tips:

  • Sow seeds 1.5 cm deep in rows spaced 30 cm apart
  • Keep the temperature steady at around 14°C

Nurturing Your Onion Seedlings

After your seeds have germinated, a bit of care is needed to ensure healthy growth.

Indoor Seedling Care

Prick out seedlings into individual pots or modular trays. By April, these should be ready to move to a cold frame to harden off.

Outdoor Seedling Care

If you’ve opted for outdoor sowing, your first task will be to thin the plants. Achieve a final spacing of 15-30 cm between each plant.

Getting Ready for Harvest

As your onions mature, you’ll want to keep an eye out for the ideal harvest time.

Harvest Time

Your Onion Ailsa Craig should be ready for harvest from August to September. Handle them carefully to ensure they remain in top condition.
