This year was good locally for onion crops. Copra is the mainstay in my onion patch, being an all-around good onion for cooking, soups, stews & grilling. What's more, it keeps through the winter when cured and stored properly. I've kept them successfully over winter through March into April. This year produced large, firm onions, with the largest weighing 1 pound 2.8 ounces. I might add they add a nice zingy flavor to grilled burgers.

This is my fourth year raising these onions, and there are no regrets nor disappointments. I recall a note I had made in September 2009 in my garden notes. Here is part of what I had written then: This is my first year raising Copra onions, and they are about what I had expected from reading about them. They are medium sized, usually no more than 3 to 4 inches in diameter. I grew them for winter storage -not size. A quote from the supplier reads, "This is the best storage onion available. Its extra-hard medium-size bulbs will provide you onions for cooking until you have to plant again. The blocky round shape and thin necks allow the onions to dry quickly and they still have the highest sugar content of any storage type." Unquote.
Four years later I am very satisfied with the overall quality of this onion. We usually have them in storage until about April 1st. Just as any other plant in the gardens, it can be affected by weather conditions. This means (to me) that problems can arise, including fungal diseases, moles, flooding, and high wind damage. 2013 has been a good year for all the onions locally.
