Basic Onion Growing Info

Sun Requirement: Onions require full sun – the more the better! Therefore, avoid planting next to crops that might shade your onions.
Soil Fertility: Onions prefer soil with a pH between 6.2 and 6.8. If your soil is too acidic, add ground limestone; if it is too alkaline, add peat moss. Adding compost or a balanced organic fertilizer is essential for growing healthy onions, especially if your soil fertility is low. For the best growth and yield, onions need fertilizer at planting time and additional side dressing.
Planting: Onions grow best on raised beds or raised rows at least 4″ high. Typically, onions can be planted as early as 4 to 6 weeks before the last estimated spring frost.
