(Allium cepa) This is southern Oregon grower Don Tipping of Siskiyou Seeds' selection of the classic Walla Walla Sweet onion, the most famous of the northern adapted sweets. Very large, slightly flattened bulbs are juicy, mild, and very sweet. We have heard tales of people eating these like apples. The original seed was brought from the island of Corsica to WA by French soldier Peter Pieri around the turn of the 20th century. Not a keeper.
110-120 days. Long day. WG

Packet: 100 seeds

1/4-1/2"

SPACING:

4" spacing in rows 15-24" apart.

7-14 days @ soil temp 60-75F

Full sun

FERTILITY:

Medium-Heavy. Prefers well-drained, loamy, well-balanced fertile soil with a pH between 6.0-7.0.

ADDITIONAL NOTES:

Alliums would like you to keep them well-weeded as they are slow-growing and compete poorly.

Onion bulbing is sensitive to day-length.

Shallow-rooted onions prefer even watering.

Harvest when the tops have fallen over. We sun-cure, placing the bulbs on screens and taking care to cover each one with the next onions leaves.
