Prime-Ark® Freedom Primocane Blackberry Plant

Put a piece of green flagging on the 1st year cane. Add a piece of blue flagging to the cane when it reaches the second year. In the fall, after it fruits, cut down the canes with both blue and green flagging.
Eventually you won't need to mark the canes, because you can tell them apart. But until then, the flags will show you exactly what year the canes are on.

Thank you for your question! Our blackberry plants in the Jumbo Cell Pack have a shipping expectation of 4-6" tall. In the small gallon, they are about a foot tall with an advanced root system.

No, blackberries produce on previous years growth. Prime-ark varieties will also produce some on new growth later in the season. After last years growth is through producing it then needs to be pruned out.
Ours are now 1+ years old, last years growth is loaded with berries and still blooming. We are seeing several new healthy shoots coming up and are making us look forward to even more berries next year. hope this helps.

CAN you prune them down to 6" or to the ground? YES, YOU CAN DO WHATEVER YOU WANT! Make it work for your space and comfortable for your garden style. If you do, will get fruit? Probably!!! These are PRIMOCANE. They will fruit on first year canes, and also again on the second year. We have them established along a handicap ramp leading to the porch (no thorns!) and cut them down to about knee height in winter. They leaf out nicely and provide beauty and fruit yearly. Don't be afraid to prune them back as they are quite a vigorous cultivar. Have fun and make your garden work for you!

I would say that the seeds are of average size for a blackberry. However, the blackberries themselves are very large, juicy and sweet. I planted mine in April 2015 and by September it was 5' tall and 3' wide. Some berries grew 1.75" long. And all on the primo canes with no thorns. Truly an amazing variety!

Well
I would order the paks because you will have to get the plant established with the soil and first Year is light production. Get more for your money and be patient second year would be good Third best. Do the placement, mulching, and pruning otherwise it will be a waste

My brother lives in Northern Kentucky, near Cincinnati. I gave him some and he is able to grow them. It wouldn't be as far north as you, but my guess is they would survive and thrive there. The variety was bred at the University of Arkansas for that general climate. Blackberries are fairly resilient and will grow most places in the lower 48. I advised him to keep his in the garage the first winter to allow them time to develop roots and get established. He did and the next year after he planted them outdoors, they were productive.

It is normal. Mine did that. What I have found out from reading, not experience, is to keep them trimmed back. Of course, the thing that must be done each year is to cut the blackberry floricane (the branch that has already had berries) back all the way to the crown.

It is not a super sweet berry. I found it great when making Berry melomel because it has LOADS of flavour and colour which is great when you are adding honey. It makes killer jelly/jam and ice cream! It is CRAY productive!

Yes, blackberries grow well in containers, but they must be sufficiently large to allow for root growth. I start mine off in smaller 3 to 5 gallon containers and eventually transplant them into 15 to 20 gallon pots. In containers they will need to be watered more often than when planted in the ground. I suggest you mix in some coco coir or peat moss to keep the mix lighter so roots can grow with less effort and water retained. You may occasionally find some which don't adapt well to this type of growing environment as blackberries can have substantial root systems. I have rocky clay style soil where I am which is why I plant this way. Good luck.
