Yellow Onion Seeds

Onion seed starting is easy. Onions grow best in fertile, well-draining soil. This should also be worked with organic matter, such as compost. Onion seeds can be planted directly in the garden bed. However, when growing onion seed, some people prefer to start them indoors. This can be done in late autumn. The best time for planting onion seeds outdoors is in spring, as soon as the soil can be worked in your area. Place them about an inch (2.5 cm.) deep in the soil and approximately half an inch or more apart. If planting rows, space them at least one and half to two feet (.45 to .61 m.) apart. When it comes to onion seed germination, temperature plays an active role.
