How to Grow Onions

For onions to grow properly, the soil needs to be loose and well-draining; compact soil will affect the size and shape. Onions are heavy feeders, so be sure to use rich soil and fertilize every month or so. Sow seeds in a sunny location.

After the risk of frost has passed you can directly sow the seeds outdoors. Sow the seeds 1/4 inch deep, spaced 6″ inches and  in rows 12″ apart.

If starting the seeds indoors, sow seeds 4-8 weeks before last frost. The ideal temperature for germination is around 20-30 C. Seedlings can be transplanted outdoors after they have at least two sets of leaves.
