Senshyu Yellow Onion Sets

Senshyu Yellow is a reliable Japanese onion specifically suited to overwintering. Plant the sets in autumn so they establish before winter and resume growth in spring, giving an earlier harvest than typical spring-planted onions. The crop forms semi-round bulbs with straw-coloured skins and a mild, versatile flavour.

Planting Advice

When & Where to Plant

Plant from September to November so the sets can establish before winter. Choose full sun and fertile, well-drained soil.

Spacing & Depth

  • Plant sets 10–15cm apart, with 20–30cm between rows.
  • Leave the pointed tip just showing above the soil.
  • Check newly planted sets regularly or protect temporarily from birds until rooted.

Winter Drainage

Overwintering onions dislike sitting in waterlogged soil. On heavy or wet ground, use raised beds, containers or modules and plant out when conditions improve.

Harvest & Storage

Autumn-planted onions generally mature earlier than spring-planted crops. Lift when the foliage yellows and topples, then cure thoroughly before use or storage.
