How to Propagate Blackberries

How do you propagate blackberries? It’s so easy! Probably the easiest of all the plants, trees, fruits, veggies that I propagate. All you do is cut off a piece of blackberry vine and stick it in the ground where you want it. Or let it grow until it’s tip touches the ground.

The First Way

When your blackberry bushes are done producing and you’re ready to cut them back, don’t throw away all those pruned canes! Instead, cut them into 12″ pieces and stick them in the ground wherever you want more blackberries to grow. I do this from August to October but you can do it anytime you’re pruning them. During the summer they are growing and producing so you wouldn’t prune. However, if one cane is super long and doesn’t have berries on the end, I will cut it off so it stays out of the way of the lawnmower. So I do propagate during the summer sometimes too. I walk by, get hit in the face with a blackberry cane, pull out my shears, cut off 24″, cut it in half, and stick both halves into the ground wherever in my garden/yard I want more blackberries. So easy!

A Second Way

Another way to propagate blackberries is to let them grow super long in the summer and by early fall the tip will bend over, reach the ground, and start putting out it’s own roots even though it’s supposed to be the top of the plant. Then after a few weeks you can cut it off and it’ll be growing all by itself.

Cut it with pruning shears, leaving about 12″ in the ground. Then you can stick the tip back into the ground to produce more roots. Or cut more 12″ pieces off of the long cane and put them in ground wherever you’d like blackberries to grow in your garden.

If you’re planting in the summer: Water them every day (unless you get a lot of rain like I do.) They’ll start to grow and you’ll notice new leaves/growth on the canes.

If you plant in the fall: No need to water unless it’s hot and dry. They will look dead all winter but in the spring they will grow new leaves and height.

The first summer they grow about 24″. The next summer they will grow much more and produce fruit.

Here are some pictures of our blackberries:

One day when Alexis had taken all the kids places I got out the fancy camera and actually took some good pictures around our property! This is my favorite. I’m always going and don’t usually have the time or patience but my goal for 2023 is to learn how to use the camera and take better pictures.

We love blackberries on our farm! Sadly we lost a patch due to the driveway construction, I’m hoping it will come back, I may help it a bit !
