Description

Triple Crown is a thornless, semi-erect blackberry valued for large fruit and excellent flavor. It is a summer-bearing cultivar that fruits on second-year canes (floricanes) and ripens later than most trailing blackberries.

  • Plant form: One dormant bare-root plant
  • Growth habit: Thornless, vigorous, semi-erect floricane bearer
  • USDA zones: 5–9; protect overwintering canes at colder or exposed sites
  • Chill requirement: Approximately 300–500 hours
  • Pollination: Self-fruitful; flowers still depend on pollinator activity for good fruit development
  • Sun: Full sun
  • Spacing: About 5 feet between plants
  • Harvest: Typically late summer into early fall in mild climates; timing varies by region

Training and care

Plant in fertile, well-drained soil and keep the root zone evenly moist. Use a sturdy trellis for the long, arching canes. Tip primocanes in summer to encourage lateral branches, shorten laterals during dormant pruning, and remove spent floricanes after harvest.

Shipping and resources

This seasonal plant ships dormant and may arrive without leaves. Browse all berry plants and review the Blackberry Growing Guide before planting.

Crop sequence and harvest

Mark or separate the current season’s primocanes from fruiting floricanes as you train the plant. This makes postharvest removal easier and protects the canes needed for next year. Secure long growth to the trellis before it becomes tangled, keeping the row narrow enough for light and picking access. Triple Crown fruit should be harvested when fully dark, glossy to slightly dull, and easily released; berries do not improve after picking. Yield and ripening depend on winter cane survival, pollinator activity, irrigation, and summer weather.

Guarantee

Limited Dormant Tree & Plant Guarantee

* Claim deadline is June 15th

We guarantee that your dormant tree or plant will arrive in good, viable condition. If your tree arrives in substandard condition, notify us within 3 days of delivery. Please email pictures of the box, inside packaging, the tree and its roots to helpdesk@groworganic.com.  We will investigate your claim and process a request to exchange or refund the damaged product.

If your dormant tree or plant has not grown new leaves by June 15th, you may be eligible for our Limited Dormant Tree & Plant Guarantee. This guarantee provides for a store credit for the purchase price of the tree, excluding shipping. Please see the Instructions below.

Important Dates:

  • April 1st Dormant trees/plants must be planted in the ground
  • May 15th Perform scratch test, if no new leaves have grown
  • June 15th Deadline to apply for a dormant tree/plant credit

All required documentation must be received by June 15th for your claim to be considered. Claims or documentation received after June 15th will be denied, without exception. Instructions listed below

Terms and Conditions

We cannot guarantee that your tree or plant will remain alive and healthy after it is received, or bear fruit as there are too many variables in your environment that are beyond our control (i.e. soil preparation, weed and pest control, proper irrigation, chill hours, compatible hardiness for your growing zone, proper choice of pollinator, extreme weather, rodent damage, disease, etc.). 

We cannot guarantee that we will be able to provide a replacement tree/plant of the same species either that same growing season or in future years. Customers are responsible for all shipping fees associated with replacement trees and plants. 

If we determine that the tree you purchased directly from us is not viable, we will issue you a store credit (not a refund) for the purchase price of the affected dormant tree or plant. Shipping is not included in the dormant tree/plant guarantee. Store credits can be used to purchase any product we sell and are valid for use only until July 1st of the following year.

Historically, 98% of our dormant trees and plants grow and thrive when they have been cared for and planted using our growing guides. Dormant trees and plants must be planted in the ground by April 1st in order to be eligible for credit. If the ground in your area is still frozen solid, you may temporarily plant your tree or plant in a pot. 

Potted, non-dormant trees or plants are excluded from this guarantee as they are not dormant at the time of shipment. Evergreen trees such as citrus, avocado and olive trees are not available for credit under the Dormant Tree and Plant Guarantee. 

Instructions

We guarantee that your dormant fruit tree or plant will leaf out, if you care for it according to our growing guides. In the unlikely event that your dormant tree or plant does not have leaves by May 15th, follow these simple steps to apply for a store credit:

Before you call or email, please perform a “scratch test” to determine if the tree or plant is still alive. This video shows how to check for live tissue under the bark. Scratch tests need to be done a few inches above and below the graft. 

Green Cambium Layer / Living Trees

If the cambium layer under the bark is green, give your tree a little more time. It is still alive, but hasn’t come out of dormancy yet. Check to make sure that it is getting the right amount of deep root water, enough sunlight and that the weather is warm enough for that type of tree/plant to come out of dormancy. Every tree has its own personality and will come out of dormancy at different times. Be sure to submit the required documentation listed below by June 15th, if it doesn’t grow leaves.

Brown Cambium Layer / Dead Trees

If the scratch test shows a brown cambium layer or if your dormant tree/plant doesn’t have leaves by June 1st, please email us at helpdesk@groworganic.com. All required documentation listed below must be received by June 15th for your claim to be considered. To be considered for the guarantee claim, all required documentation must be received by June 15th.  Incomplete submissions will be denied.

Required Documentation

  1. Order number
  2. Name of dormant tree/plant and the quantity affected
  3. Photos of each tree or plant showing: 
    1. The roots (tree or plant must be pulled out of the ground)
    2. The scratch test areas
    3. The entire tree/plant

We reserve the right to not issue credit for items that have already been replaced. We also reserve the right to require photographic evidence that the tree/plant was not killed by root rot, rodent or mechanical damage.
