Out of all the vegetables the onion is one of the home gardener's favorite. There are several reasons for this. The onion is easy to grow, doesn't require much space, and has lots of medicinal and culinary uses. Onions also have such a variety that a gardener can find at least one type of onion that will fit their needs.
There are many different types or varieties of onions. Listed here is just a sample of the more commonly known onions and what they are known for.
While there are many different varieties of onions there are actually only two different classes: long day and short day. Short day onions are mainly grown in the South, and the long day onions are more for the North. The short day onions develop bulbs with about 12-14 hours of daylight while the long day onions require 14-16 hours of daylight.
There are three different options that can be used to grow onions:
In general, onions should be planted three to four inches apart. Double rows that are about eight inches apart (give or take a couple of inches) won't hurt anything.
When it is time to harvest onions it is usually fairly easy to tell. When the tops have fallen over it is time to pull them. After pulling the onions rinse off the dirt and then allow the onions to dry in the open for a couple of days. Then cut the roots and the tops off. Leave the onions to set out in the open again for a couple more days.
