Planting & Care

Where to Plant

Sunlight: Give this blackberry bush a spot with full sun, receiving at least 6 to 8 hours of direct light daily for the sweetest berries and heaviest yields. While it can survive in very light shade, you will notice a significant drop in fruit production and quality.
Soil: Plant in well-drained, slightly acidic soil that is rich in organic matter. If you are dealing with heavy clay or poor drainage, amend the site heavily with compost or plant in a raised bed to prevent root rot.

Watering Requirements

Consistent moisture is critical during the first season to establish a deep root system, so check the soil weekly and water thoroughly whenever the top inch feels dry. Once established, these plants are moderately drought tolerant, but inconsistent watering during fruit set will result in smaller, tart berries.

Pruning Tips

Triple Crown bears fruit on second-year wood (floricanes), so you must prune the canes that just finished fruiting all the way to the ground after harvest or in late winter. During the summer, "tip" the fresh green shoots (primocanes) when they reach about 4 to 5 feet tall to force side branching, which effectively increases your fruiting surface area for next year.

Fertilizer Needs

Apply a balanced 10-10-10 fertilizer or a layer of compost in early spring just as new green growth begins to emerge. Avoid applying high-nitrogen fertilizers late in the growing season, as this pushes tender new growth that is easily damaged by winter frost.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

#ProPlantTips for Care:

Give Bramble plants full sun so they can achieve fruit production in abundance. Space Blackberry plants five feet apart. Leave the new canes in place to fruit for next year. Hardy throughout USDA growing zones 5 through 9! Plant in well-drained soil with moderate moisture throughout the growing and fruiting season. Provide a layer of mulch over the root system to hold in moisture and insulate the roots.

Prune or top new floricanes back to 5-6 feet. Tip prune the canes back once they reach 42 inches to encourage fruiting laterals and maintain the upright, bushy form. Once canes have fruited, and been harvested, cut those canes right down to the root.

Frequently Asked Questions

What USDA hardiness zones is the Triple Crown Thornless Blackberry Bush suitable for?

Triple Crown Thornless Blackberry thrives in USDA zones 5-8. This hardy variety tolerates winter temperatures down to -20°F while producing up to 30 pounds of fruit per mature plant. Plant in full sun with well-draining soil for best berry production.

How tall and wide does the Triple Crown Blackberry Bush get at maturity?

Triple Crown Blackberry reaches 4-6 feet tall and 3-4 feet wide at maturity. This compact, thornless variety has a tidy growth habit that's easy to maintain. Space plants 4-5 feet apart for proper air circulation and easier harvest access.

Is the Triple Crown Blackberry Bush thornless?

Yes, Triple Crown is a completely thornless blackberry variety. The thornless canes make harvesting safe and easy, so even kids can pick berries without getting scratched. This feature makes it ideal for family gardens and edible landscaping where people frequently walk by.

What are the sunlight requirements for growing Triple Crown Blackberry successfully?

Triple Crown Blackberry thrives in full sun, requiring at least 6-8 hours of direct sunlight daily for maximum fruit production. The product description mentions "putting your sunshine to work," emphasizing this variety's need for abundant light. Plant in the sunniest spot available in your yard for best berry yields.

What type of soil and drainage does the Triple Crown Blackberry Bush need?

Triple Crown Blackberry thrives in well-draining, slightly acidic soil with a pH of 5.5-6.5. Plant in full sun locations with good air circulation to prevent fungal issues. Amend heavy clay soils with compost for better drainage, and shop at Nature Hills for healthy, field-grown plants.

How often should I water the Triple Crown Blackberry, especially during fruiting?

Water Triple Crown Blackberries deeply once or twice weekly, providing about 1-2 inches total. During fruiting season, maintain consistent moisture as irregular watering can cause poor berry development. Check soil 2 inches down and water when dry.

What are the pruning requirements for Triple Crown Blackberry after harvest?

Remove all canes that produced fruit this year, cutting them to ground level in late fall or early winter. Triple Crown is a floricane variety, so only second-year canes bear fruit. Thin remaining first-year canes to 4-6 strongest shoots per plant for optimal production next season.

Can the Triple Crown Blackberry Bush be grown in containers or pots?

Triple Crown Blackberry can be grown in containers, though it performs best in the ground where it can reach full maturity and produce up to 30 pounds of fruit. Choose a large pot (at least 20 gallons) with drainage holes for container growing. Expect smaller yields but still enjoy the thornless, self-pollinating benefits with proper care and regular watering.

Triple Crown Blackberry plants are covered by a standard nursery guarantee against shipping damage and initial establishment issues. Most reputable nurseries provide a 30-day guarantee on healthy arrival and early growth performance. Check your specific warranty terms upon delivery and contact customer service immediately if you notice any shipping damage or plant health concerns.
