Organic Onion Seeds — 'Yellow Spanish Utah'

Overview A hardy crop grown globally, onions are a staple in vegetable gardening. They can be grown for their mature bulbs, or simply for their green tops. Rich in dietary fiber, vitamin C, potassium, iron, and organosulfur compounds, onions have been linked to cancer prevention and lowering blood pressure and cholesterol.  Conditions Onions are a hardy crop adapted to a wide range of growing conditions. Day length is important in variety selection of bulbing onions. Growers north of 38 degrees latitude should plant long day varieties as early as possible to achieve full size prior to maturity. Growers south of 38 degrees should plant short day or intermediate day varieties as these need less day length to reach full size. Green/bunching onions can be grown at any latitude. Onions grow best in fertile, well drained soils with a pH of 6–6.8.  Planting Use our grow calendar tool to find specific dates for your region! Seeds germinate in 10-14 days.
