Hi, this is Yolanda Vanveen and I'm here to talk about how to harvest and store onions. Now I love onions in all of the dishes. It doesn't matter if you're cooking Chinese food, American food or making a nice stew, it's great to have onions in it. And they're a easy plant to grow in your garden as well, because they don't ask for a whole lot. They just want a full sunny spot with some water and room to grow. I found that onions are pretty easy to tell when they're ready to dig up and so what I found if you just let 'em grow through the summer, by late summer, they'll actually start turning a bit yellow. The foliage will start turning a bit yellow, even with watering, it will just get to the end of it's cycle. And at the point where the leaves are just barely turning yellow, then I'll just dig up a few of them and see if they look firm and if they look like they're ready to grow. Sometimes you, I might just throw 'em back in the ground for another couple weeks 'cause they'll continue to grow even where the foliage is dying back, but it is a good rule of thumb. And doesn't matter what shape or size they are. They can be large or they can be smaller. They seem to all grow really well and be easy to use. So when you're storing onions, the best way to store 'em is in a root cellar or somewhere in the garage or somewhere that they can get, stay cool but not wet, and not too moist but not dry, and so you can keep 'em in the refrigerator or you can store 'em just in a box in the garage and then that way, they will last nearly all winter long, and sometimes up to two or three months even. So when you're digging up your onions, the leaves will turn yellow, so you know it's time. So the easiest way to do that is take 'em out of the ground, just dig 'em right out and let 'em sit right where they're out or dry them out in the hot sun with the greenery for at least two to three days. Once that greenery's really dry, and the onions look like they're on the dry side but not too dry, just so that the greenery is pretty much died back, cut the greenery off and you can take the onions and either store them in the garage, the root cellar, or right in the refrigerator. And as long as they stay, have some humidity, they will stay for three, four, even five months and you can enjoy them all winter long.
