I want a late-bearing thornless blackberry since the farm where we usually u-pick harvests in July. Our own blackberry will ripen in August and we'll enjoy the last sweet taste of summer!

Do they creep if planted in the ground?
TROY N on Mar 22, 2016
BEST ANSWER: This variety sends out lateral branches along the ground. They should be pruned back to 12 inches and they will then run and produce new growth. All varieties of blackberries should be trained to a fence or posts with plenty of air within the leaves. By pruning the laterals to 12 inches you will have a better harvest. Let me explain a bit more. The laterals to be pruned to 12 inches should be the first year. If you have second year vines 4 feet or longer you need to stake these or train to a fence. I use plant Velcro ties to do this. Do not prune huge lengths off your second year vines or you will end up with less harvest. Triple Crown Thornless will stay at ground level, creep and start new rooted shoots if not trained to be upright. Some plants can get as long as 16 feet so you need a lot of space to grow the lateral branches at ground level.
How large are these plants?
Gillian L on May 23, 2016
BEST ANSWER: Thank you for your question! Our Jumbo Cell Pack plants will be shipped at 4-6" tall, while the gallon-size container plants will be approximately 12" tall.
My wife and I are having difficulty with several of these purchased over the last several years not producing fruit. The canes are long, strongly, and a nice color with full, dark green leaves coming out at the ends. But, they produce either shriveled, dry small berries or none at all. What we don't understand is how the canes can be so healthy (they are getting a full dose of Texas summer sun), but not result in any harvest. Any suggestions?
Tim S on Aug 28, 2016
BEST ANSWER: Vegetative growth has different needs than the fruit. For example, if you're fertilizing with a high-nitrogen fertilizer, it would encourage the growth of canes and leaves but not flowers or fruit. Some blackberry plants don't mind the heat, but the fruit may not do as well in the heat if the plants aren't getting enough precipitation or irrigation. Cutting back on fertilizer, providing a temporary shade structure over the plants while they're blooming/fruiting (with gardening shade cloth), and making sure the plants get enough water should help improve fruit quality and production.
Can the Triple Crown Blackberry variety be container grown?
Stephen S on Oct 18, 2016
BEST ANSWER: Triple Crown Thornless Blackberry can be grown in a container. A container that is 5 gallons are larger. Since blackberry plant's roots spread out instead of down a shallow container can be used.
The plant will need about 10 inches of potting soil or soil less mix.The container will need holes
in the bottom for drainage. The blackberry vine will need some type of support.

The blackberry will need pruning and training. It may outgrow the container so divide the plant the plant during the winter when it is dormant.
I bought Triple Crown 2 years ago and the vegetative growth has been tremendous. We enjoyed some tasty sweet blackberries after the first year. I was looking forward to this year since the vines were so huge. We had a lot of berries, however the taste was bitter. We are located in MA and we experienced very low levels of rainfall so perhaps that impacted the flavor. These were not irrigated. I read that perhaps the soil pH is too low as well (mine is around 5-6). Does anyone have any advice on what I can do next season?
MattJ on Nov 6, 2016
BEST ANSWER: We also had a very dry summer here in Stonington, CT and not that it helps much, like yours, my berry production was way down. My drip lines do not extend to my berries (red, yellow and black raspberries, Triple Crown Thornless Blackberry and wild raspberries). I was too late in noticing that the druplets were not filling out and the canes were small and weaker than normal. Berries were weak looking and tasting. I would not say bitter so this may not address your problem. The triple crowns were just very slow too mature and much fewer in number. A wives tale says add cow manure for the best tasting berries but I just use 1lb of Nitrogen per 100 ft of berries (thats 2.2 lbs of 45-0-0 urea specifically) after the berries set.
BTW I recommend "The Berry Grower's Companion" by Barbara Bowling.
Sorry, no easy answer. Oddly, irrigated blueberries produced record crops of perfect berries.
Is it O.K. to put grass clippings around blackberry canes?
Doug K on Mar 5, 2017
BEST ANSWER: It's not recommended after the first year and first year mulch should be weed frre like clean straw mulch. Worry is for development of Phytophthora root rot associated with grass mulch on heavy soils (clayey vs. organic). If this shows its the end of your plants so better safe is the idea here. Growing grass between rows is commonly done however. ref. Berry grower's companion by B. Bowling.
what does semi-trailing growth habit mean ? thanks, vaughn
vaughn on Jun 8, 2017
BEST ANSWER: Different blackberry varieties have different growth habits: Erect canes will stand up on their own without support. Semi-trailing and Trailing varieties' canes do not remain upright as they grow. The canes of this variety have more of an arching growth habit that may require support to keep the canes and future fruit off the ground.
I had a lot of new starters from ends of my berries, will they still produce this year after I cut the ends to plant the starters?
mary c on May 11, 2017
BEST ANSWER: Blackberries produce on second year canes. You can plant the new canes this year and they should produce berries next year.

Triple Crown Thornless Blackberry
The size, quality and quantity of the berries were outstanding compared to other varieties. They took root easily after transplanting.

Triple Crown Thornless Blackberry
It is certainly way too early to write a review of how I like the Blackberries as I received them late last fall and immediately planted them. I would like to comment on the packaging as the plants came well watered and protected by both plastic and cardboard inside the sturdy sealed mailing bag. They appeared to be very healthy growing plants, unlike items I've received from other nurseries. I've recently checked on them and they appear to have survived the winter and are ready for spring. Hoping to use them to make wine when they start producing berries!

Super Great Flavor!
We are in the third growing season, so getting our first real crop from these plants. We purchased two to plant in our patch with other varieties. WOW!! Size, yield and flavor (triple crown) are all phenomenal, but especially the flavor!! Our other varieties are tart, these, if allowed to totally ripen on the vine are sugar sweet! The whole patch will be replaced with these over the next couple of years.

Taste is GREAT!
I love these berries. I am in Eastern Washington, and they are hardy, easy to grow, beautiful and bushy, and taste fabulous! This was our first harvest year (3rd year in the ground), and we couldn't get enough of them. For East. WA, they ripen in late July with the main harvest in the first 2 weeks of August. Best for picking and eating when the berry is somewhat softer and comes off/falls off easily when you pull on it. If you have to tug to get it off the stem, let it sit a few more days. They are worth the wait! These thornless plants are especially good for parents with small children and for people who want "edible yards."

Fantastic Berries!
These berry bushes are vigorous growers and have done well for us. The third season after planting they produced a nice amount of berries. The berries are the size of your thumb and make excellent juice for jelly making! Entering our local fair, the berries won 1st place and also won 1st place with blackberry jelly! That's a "Double Blue Ribbon"! I'm looking forward to picking loads more of these berries this summer and highly recommend this blackberry.

Plants did not grow very big
One plant did not come up after our mild winter. Three of the other plants are very small. I did have one plant that is growing great!.

Not 100% happy, but this is the first time I have planted blackberries.

So far so good
So far they are doing great. Easy to grow and take care of. Healthy plants. They are blooming right now in this area and are full of blooms so I expect there will be several berries. There have been a few berries set on but I can't tell anything of the size or flavor until they are ripe. I have no complaints at all right now and if they produce as expected I am sure I will be extremely happy with them.

Good tasting, hardy, easy-care
I put my plants in under less than optimal conditions and this has been a difficult weather year. Nonetheless, they are thriving and have produced a handful of berries with good flavor and texture. I'd recommend these to anyone who wants a nice berry crop with minimal effort.

Grows like a tree
Planted these things about 3 years ago and this will be the 1st year they are going to bear fruit. The things are growing like a tree the main stacks are over six feet and about the diameter of 3 fingers put together. There should be enough berries to feed a few families. Now if I could just figure out how to keep the berries fresh all year.
