Brenda has an excellent question and I’d like to think that I have an excellent answer. I’ll let you be the judge of that.
“I have a question about blackberries. We have wild ones growing all around us, and I’ve noticed that one plant never has thorns and there’s one that does. Is the one without the thorns the male plant? Is it ok to cut those down and leaves the ones with the berries? Is there a good way to transplant blackberry bushes, some grow right in our flower beds, can I move them? I’ve been wondering about these thorny ones for years that don’t produce fruit, so maybe someone will tell me about them. Thanks.”
And then later:
“I see I made a mistake in my email. I meant to say that both have thorns, but only one has berries. Please help me to figure out this question, it has me baffled, as you can see. I can’t even write about it w/o messing up.”
Well Brenda, here is my expertise on the subject that I really hope will help you out!
I have to say, I don’t know a lot about berries, other than that they are very tasty! However, I have found that you absolutely can transplant the bush to another location.
To begin with, trim the bush back, removing dead branches and leaves and cutting back enough that the bush will fit in the new location you’ve picked out. They do better in spots that receive full sunlight and it’s possible that the bush that does not have berries just isn’t getting enough light. Move it to a location where it get tons of light and will not be affected by nearby plants or other blackberry bushes.
To get the plant up out of the ground, dig about 1 foot away from it, making sure you are not harming the roots. You want to make sure that you’ve got the established roots in tact; carefully ease the plant out of the ground.
The hole you dig should be twice the size of the root cluster. Line it with compost and gently put the bush in, making sure not to cram the roots. Gently fill in the soil and water it regularly.
Now that should help you transplant the bush if you choose to. As for why it is not producing berries, it could be several things, such as not having enough sun, water or space. You can try fertilizing it as well. This Miracle-Gro Quick Start With Vitamin B1 is perfect for this situation because it helps ease plants into being transplanted and lessens the shock of a new environment.
Another reason it may not be producing berries is because it’s just a dud. Sometimes plants just don’t feel like doing what they’re supposed to. We have a wisteria plant on our back deck and it grew and grew but it never bloomed, for nine years! And finally, two years ago it bloomed, and it bloomed again this year. So it’s possible that your blackberry bush is just being stubborn and hopefully moving it to a new location will stimulate it enough so that it will do what it’s supposed to!
Thank you for your great question Brenda! I hope this helps!
