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: 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 throughout the growing season. Our Keene Garlic Fertilizer is great for all alliums!

Planting: Onions grow best on raised beds or raised rows at least 4″ high. It is typical to plant onions as early as 4 to 6 weeks before the last estimated spring frost.
