Walla Walla Sweet Onions Delivery or Pickup

Walla Walla sweet onions keep for about three to six weeks in a cool and ventilated place. They do not keep for very long if the air is not ventilated and cool. They can also be frozen in containers or plastic freezer bags to keep through the year. Freezing the onion is best to use for cooking later. Optimal long-term storage would be to keep the onions in near-freezing temperatures with good humidity and ventilation.

Walla Walla sweet onions need significant moisture in the first few weeks of growth. Keep the soil moist and mulch to maintain the moisture and for weed control. They can also be started indoors if the growing season is short. You can start indoors in late winter ten to twelve weeks before planting. These onions need full sun in northern areas and partial shade in hotter areas. In the northern states, the seed is sown in late August to be harvested in the summer. Colder winter areas are where seeds get sown in early spring. When the tops flop over, it means they are ready to be picked out from under the soil. They can also be picked fresh once they reach the desired size.
