Nicole Johnsey Burke shows how to grow thornless blackberries like Triple Crown or Chester on a homemade arch trellis. Most U.S. blackberries come from one Mexican region and are chemically treated, but yours will be organic. Plant one cane per side, wait three years for the cycle to complete, and harvest daily once berries turn black.

3 out of 4 of the blackberries Americans eat were all grown in just one region of Mexico, and most were chemically forced to fruit. But almost all of us can organically grow our own blackberries at home. Today I'm going to show you how to do it. Grow it on an arch trellis directly in the ground. You can make your own with cattle panel, or you can get a kit like mine. Then you want to use a semi-erect, thornless variety. My favorite is Triple Crown or Chester. You're going to plant one blackberry on either side of the arch trellis, add a little bit of compost, and you're ready to go. The canes grow over 3 years. The first year is called the primocane. There's no fruit. You're just going to tuck it in and out of your trellis and just let it be there. Second year is the floricanes. This is the year you're going to get the most fruit. Make sure these have a lot of support on your arch trellis. The third year, the cane will just stay dead at the base of your plant. It starts as a flower, then these green clusters, then red, and then black. Once they turn this color, your job is to pick, pick, pick every single day, and then when you're about a month away from your first frost, you're going to top off the cane right here so all the fruit finishes up.
