Be sure to test your soil first to find out. Using a mixture such as 10-20-10 or 0-20-0 will provide an extra boost for your developing onions. At this point, be sure to remove any weeds that may be present in the garden plot you're planting in. Plant onions so that no more than one inch of soil is placed above the sets or seedlings; if too much of the bulb is buried, the growth of the onion will be reduced and constricted. Space onion sets 46 inches (10.215.2cm) apart, and onion seeds 12 inches (2.55.1cm) apart. As your onions begin to grow, you can transplant them and space them further apart in order to increase their growing size. Place your seeds in the holes you've dug, covering them with to inch of soil. The sets should be no more than two inches deep. Use your hands or shoes to firmly tamp the soil over the top of the onions; they grow better in firm, rather than loose, soil. Finish up planting by adding a bit of water, and you're set to watch them grow! Transplanted onions require more water than sets or seeds, so give yours a little extra moisture if that's what you planted. Onions are relatively delicate plants, as they have a fragile root system that can easily be damaged or abused by weeds and tugging. Use a hoe to cut off the tops of any weeds that emerge, rather than pulling them out; tugging the weeds could tug out the roots of the onions, and make growing difficult. Give your onions about 1 inch (2.5cm) of water per week, and supplement with a nitrogen fertilizer once a month for nutrients. Immediately after planting, add a light layer of mulch between each plant to lock in moisture and block out weeds. If you want your onions to taste a bit sweeter, give them more water than you normally would. If any of your onions flower, pull them out. These onions have 'bolted' and won't continue to grow in size or flavor. Onions are fully ripe when the tops appear golden yellow; at this point, bend the tops so that they lay flat on the ground. Doing this will move further nutrients towards developing the bulb rather than growing the shoots. After 24 hours, the tops should appear brown and the onions are ready to be pulled. Remove them from the soil and trim off the shoots at 1 inch (2.5cm) above the bulb and the roots. Leave the onions to dry out for a day or two in the sun, and then move them to a dry space indoors for two to four weeks to continue drying. Store onions in stockings or over a wire screen to allow good airflow when drying. This will help them to keep for longer and maintain their flavor. Sweet onions will go bad earliest because of their high moisture content, so eat them first in order to prevent rot from making an appearance. Discard, or cut up and use, any onions that show signs of decay so they don't spread disease to other onions in storage.
