‘Senshyu Yellow’ Onion Sets (50 Bulbs)

‘Senshyu Yellow’ Onion Sets produces an extremely popular Japanese overwintering onion. It reliably produces a heavy crop of semi-globe shaped, straw-coloured bulbs of excellent quality, that are ideal as spring onions.

Onion sets are small immature onion bulbs that have been grown from seed in the previous year. This makes them easy and quick to plant at short notice with sets ideally planted in the autumn, in time for an early harvest the following year, around June or July.

These sets can be grown evenly spaced in containers or in rows in planting beds. Thoroughly dig over the soil, removing any weeds and add a general fertiliser to improve yields.

Plant ‘Senshyu Yellow’ sets at a depth of 3cm/1″ and a spacing of around 12cm/5″. Check the sets every few days and re-plant any that have been disturbed by birds until growth starts.

If early hard frosts are forecast, protect the shoots with a mulch of leaf mould or straw, and water as normal when temperatures rise in late spring.
