Did you know leeks are one of the most cold tolerant of all the vegetables? They can withstand temperatures down to about five degrees Fahrenheit without dying. Hi. I'm Jarrett from Stone Soup Farm. And this is how to grow leeks. Leeks are best planted in the Spring, as soon as you can work the soil. They can survive through the Spring frosts, even those little seedlings. And so, as soon as you can get in there, you can plant leek seeds. I like to do about three or four per clump. And the clumps are about a foot apart from each other, in rows that are about 18 inches from each other. It's best to have well-drained soil with lots of compost or manure incorporated in beforehand. Keep them well-watered and weed free throughout the season for the best yields. There is no such thing as too late to harvest leeks. They pretty much will last in the field all summer. As soon as they're as big as you'd like them to be, you can harvest then eat them, or you can leave them. They last quite well into the Fall and even into the Winter, you can come out and harvest. When you're ready to eat them, you just grab and rip it out of the ground. It'll have a few gross leaves on the outside, which you can pull off. And underneath, you've got a lovely leek. Like I said though, they don't store quite as well once they're harvested, but you can harvest them any time of year. So just leave them in the ground, and get them when you're ready.
