How to Grow Onion Red Baron Seeds: Your Step-by-Step Guide

Beginning Your Onion Adventure

Consider Onion Red Baron Seeds for a splash of colour in your vegetable patch. These deep blood-red, globe-shaped onions are an RHS award-winning variety, perfect for any garden or allotment.

When and Where to Sow

For the best results, aim for indoor sowing from February to April. Outdoor sowing can be done in April. Here are some quick tips:

  • Sow seeds 1.5cm deep in rows spaced 30cm apart.
  • Maintain a constant temperature of around 14°C.

Nurturing Your Onion Seedlings

Indoor Seedling Care

Once germinated, transplant the seedlings into individual pots or trays. By April, they should be ready to move to a cold frame to harden off.

Outdoor Seedling Care

For outdoor sowing, thin your plants until they are 15-20cm apart.

Getting Ready for Harvest
