Rooting a Blackberry Cutting?


I just took some new cuttings off well established Blackberry bushes. How do I root them properly? Right now they are sitting in water. Thanks for the help.

Here is the easiest way to root cuttings from established plants.

  • Start with cuttings that are 4 to 6 inches long. Use new canes from established plants while the new growth is still tender.

  • Prepare a pot (or bed) containing a mixture of perlite and peat. Use a 1:1 ratio. You can also root the canes directly outdoors, but they will need time to establish themselves before winter. It's getting late in the year, so I would root and overwinter at least some of them indoors in the event that your winter weather arrives early.

  • Dip the bottom ends of the canes into a rooting hormone and insert them into the potting medium 2 inches deep.

  • Moisten the potting medium. Optional: Cover the canes with a 2-liter bottle (bottom removed, cap intact).

  • Place canes in a warm location and check to see if roots have formed after 5-6 weeks. If so, you can remove the bottle.

  • After roots have formed AND some new growth appears, transplant the cuttings into bigger pots or plant them in the desired permanent location. Don't forget to harden off indoor cuttings before transplanting them outside next season.

Upright varieties of blackberries can also be propagated by root cuttings and in the case of trailing types, it's quite easy to establish new plants by layering (bending over the new cane tips on established plants and covering them with soil).

Good luck!

I just researched what to do with coffee grounds and learned that berries of all sorts LOVE them dug in around their root system. I plan to do that with the ONE plant I have, but it is getting heavy and I wrapped it around the largest tomato cage sold. It must like it because it's alive, although has not produced berries this year. I believe I have too many canes, so I will cut them back to only a few in the Spring. It took me FOREVER to learn what the plant was by it's leaf. I thought it was Dewberry but learned it is blackberry. Hope to keep it under control, the only controlled thing around my wild herb garden, where the famous Texas Sage trees are still growing in an old pillowcase full of soil after their clay pots cracked with frost, leaving only the pillowcase they were covered in.


I trained them into small interesting trees, hoping to move/plant them
next Spring into just the right spot. I sort of lean towards Oriental Gardens, but haven't the time to devote to maintaining such, so I just give everything a kiss, a promise and much free reign, within limits.
My garden is abloom with lovely bunches of white
Society garlic, and tall dark-foliaged fragrant and bright purple trumpet shaped 1"x1" Mexican Petunias, which I LOVE and can count on each year, with a backdrop of a trellised fence and
many groomed Palmeto Palms, beneath a huge old non-bearing Mulberry tree that's content and healthy. With the many kinds of iris, the Blackberry will almost have to find it's place in that world until I tame it all again one day...LOL

Okay so I did a bad thing when I had the clippers out this year and trimmed what I should have left on my blackberry. I put the cuttings in the house in a vase, and so far they have grown leaves and one has even put on a flower, but no one has grown any roots.


Is there any hope for these clippings? I know I shouldn't have cut the plant... and I promise never to do it again!

We trellis our blackberries, but to establish new plants we let some of the stems (however many new plants you want) lay on the ground and the tips will grow into the ground and root themselves. When you are ready to transplant, cut the end that rooted itself about 6" up from ground. Dig plant up taking some of the soil with it and transplant it into it's new location.

The original plants we bought were almost $14.00 a plant when we started our blackberry patch. We bought about 120 thorn less blackberry plants. Last weekend we clipped and dug up the rooted tips. We now have enough new plants (25-30) to add another row to our 1/4 of an acre patch. Eventually we will have an entire acre of thorn less blackberries. I sold the berries last year wholesale.


This year, I will have a stand at our small town farmers market and make about $1.50 more a pint than I did last year. Coffee grounds help make the soil a little more acidic. Most berry plants need a more acidic soil than regular veggie plants and this includes blueberries.
