My logans and Obsidian blackberries are or were tied ro metal (cattle panel) trellis.
Logans survived fine that way for a few years… with winter lows like 8F 12F… but yes dies completely at 3F.
Last year cane borers wipes out my logans…
They got part of my Obsidian canes as well.
I see that as a recurring issue with west coast berries… not cold hardy enough and very subject to redneck cane borer.
They are quite common a bit to your north, but they prefer the Central Basin over the Highland Rim down your way. I helped out on a research project several years ago to collect samples for someone at Oregon State for his thesis project. I started seeing a lot more once I got my eye trained for them. They do peter out in the western parts of middle TN, so you are probably near that limit. The closest I have seen any to you is along Big Swan Creek near Hwy 412. They like moist, semi-shade areas in valleys, but you don’t find them up on the ridges where the dewberries grow.
Sometimes berries get big with heavy pruning. YMMV.
I think not pruning everbearing rasps and cutting to the ground does give the biggest and best crop for pcane fruits…
On floricane fruiting rasps… i think the opposite is mostly true…but YMMV
Wow those are the biggest black raspberries I have seen! Oh wait those are not black raspberries. I always prune my blackberries. I was talking about black raspberries in particular primocane fruiting black raspberries I would prune floricane fruiting for sure either blackberries or black raspberries.
Blackberries can grow long canes but each cane can only produce so much sugar. You can actually see this if you let one of those long canes keep growing. The berries at the end will be smaller and not as tasty. By the time nutrition from the roots get there not much is left. I found like on fruit trees limiting production produces large higher brix berries. It’s not a huge difference. Part of pruning for me is also ease of harvesting. It also keeps air flow open which helps let more sun and keeps plants dry. Less chance of leaf problems.
The biggest black raspberries were grown in the old days…ours are small nowadays. 
30 cents per plant or $8 per thousand.
Yeah talking to an old school fruit grafter I learned more than I did spending a year researching grafting. The old ways were fine for a reason. Although not always perfect. It got the job done.
All gardening is local. Talk to local people if you want to know what works where you are.
my royalties are ignored by cane borers here but my autumn britten and jacyln rasps right next to them get hammered.
Pairwise has been working with the USDA and breeders to offer what Americans are wanting such as seedless berries and also thornless. I think they will have new blackberry, black raspberry and red raspberry releases in the not to distant future.
So likely there will be seedless and thornless options in the not too distant future.
Not much of an advancement when you dumb down the nutritional value of the fruits. Goodbye seeds goodbye omega 6 fatty acids and the cancer prevention they provide. Although some say we get too much so not as bad as it sounds. Apparently we know shite about nutrition.
@steveb4 … my big stout wickedly thorny illini hardi canes have never had redneck cane borer…
22 years and not one time.
Logans and Obsidian (west coast berries) those long trailing type canes… must be their preferred targets.
I may have to stick wiith something like Kiowa for blackberries at my new place.
Squirrels and birds are apparently tougher in NY, or hungrier.
Agreed, I’ve tried educating folks on “social media” more than once… With frustrating results. So many people only know blackberries and raspberries from the grocery store and only red raspberries are sold there.
Yeah lots of native dewberry here, wonderful flavor. Wild blackberries I’m not as crazy about…
The wild black raspberries here grow OK in the open, but seem to be quite happy even in fairly heavy shade.
I usually see them along roadsides while I’m driving, so that’s why I said it’s hard to tell the difference. I think everyone in this group can easily tell them apart up close, but not while driving. I had a large patch I drove by every day and didn’t realize what they were until I stopped and took a close look one day. I’ve trained my eye for them now (while keeping the other eye on the road!), but they can still be hard to spot unless you are going really slow.
Well I could! Wild blackberries have a very different flower than black raspberries, plus they bloom at way different times. All I need is a date to tell the difference. At least in my area. The black caps are all done way before the first blackberry flower. Blackberry flowers are going to be a couple feet higher than black raspberries. Here the blackberry flower has a slight tinge of pink, black caps do not. I drive by both daily too for the last 59 years.
Drew51, the typical American diet is far too high in Omega-6 fatty acids, and most blackberry seeds pass through the digestive system intact. Blackberry seeds are not particularly healthful.
As I stated.
Although it’s like saying you’re way too healthy. You have too many cancer prevention compounds.
We should probably use the seeds in some way. Making flower would make available the beneficial compounds. From what I understand there are many different omega3 and omega 6 fatty acids. Not all are created equal.
Such as in green lipped muscles. A common nutrient supplement. One omega 3 is rare and known to help arthritis.
Interesting to know what’s in blackberry seeds.
Hello Berry Nerd! 
I have found that Berry plants do very well where I am, matter of fact, we have quite a few wild ones growing around our property. I don’t know if they’re native or not. I think one was called a cut leaf and another was identified as a white bark raspberry I think.
Anyways, we decided that we love berries and that we wanted to grow a lot of them to hopefully have enough for ourselves, friends, family, and something left over for the farmers market.
Here is what we are starting with:
Ponca
Kiowa
Caroline
Heritage
Anne
Double gold
Cumberland
Jewel
Boysenberry
Allen
Bristol
We’ve had two Latham for a couple years, they produced last year but they were kind of small and they were not bad but I don’t think we fertilized them properly and also that was their first year producing after deer ate some back and they are young. This year the canes look fantastic with a ton of new growth and we know how to properly protect them and we have a proper fertilizer now so I’m hoping we do even better this year with that variety. We also have three Ollalieberry plants from TOA that arrived last season. We planted them in 15 gallon pots this year and gave them holly tone fertilizer and they look good, they’re just not very mature yet.
Omega-6 fatty acids are bad news. While grape seed oil is the worst, the stuff sold as “vegetable oil” is soy oil, which is very high in Ω-6. Regular sunflower oil is very bad as well, but high oleic sunflower is without a doubt the best neutral oil. Avocado oil is good, but inferior in every way to HOSO, including price. Trader Joe’s sells HOHO for a very reasonable price.
What variety is this 
Natchez i believe.
