Triple Crown blackberry is a joint release from the USDA-Beltsville and the Pacific West Agricultural Research Service. The plant is semi-erect and thornless and bears large, flavorful fruit. Early trials indicate that it may ripen earlier than Chester and is similar to Chester in winter hardiness. Triple Crown would be a good choice to help extend the blackberry season for home gardeners.

Maintain your Blackberry Plants
- Blackberries should be planted 3’–4’ apart
- Recommend 8’–12’ between rows depending on machinery
- Soak in water using Agri-gel™ for 1–2 hrs before planting (except TC plugs)
- Water thoroughly after planting
- 1"–2" rainfall or equivalent per week
- Before planting add ½ – ¾ lb of 10–10–10 per 100 sq ft
- Commercial growers should use 500 lbs per acre
- An additional 1lb of 10–10–10 per 100 sq ft can be applied in July or August and in early spring in following years
- pH: 6.5–6.8
- Regular cultivation is necessary during growing season
- Roots are shallow – don’t cultivate more than an inch deep
- Mulching during establishments can help control weeds
- Contact a local extension for chemical recommendations
- We suggest plants are supported by a 5–wire trellis or put into a staked–hill system.
Don't forget Grower Accessories
Healthy berry plants require these important elements:
- Early planting! Plant as early as possible in the spring. Snow or occasional frost will not hurt most new plants (green tissue culture plants excepted), and spring rains will foster growth. Planting in the fall is not recommended in the Northeast and Midwest.
- A sunny, weed-free location with at least a half-day of sunlight.
- Clean beds that are frequently weeded.
- Well-drained soil. For poor drainage conditions, consider raised beds.
- Proper soil pH. Matching soil pH to plant requirements can be a huge factor in your success. Sample the soil before planting and contact your local cooperative extension office for assistance.
- Crop rotation. Avoid planting strawberries or raspberries in soils where previous crops have included strawberries, raspberries, potatoes, tomatoes, eggplant or peppers. These crops may harbor the soil pathogens Verticillium, Phytophthora and nematodes and may affect your new plants.
- Irrigation. Maintain proper moisture levels throughout the season and, most importantly, during the establishment period. Drip irrigation is imperative when planting in raised beds.
Avoid Common Mistakes
- Read free planting guide 1-3 months before planting.
- Plants will fail to flourish if roots are too deep or too shallow.
- Pack soil firmly around the roots.
- Do not plant near wild plants or plants whose origins are unknown.
- Water well one to three times a week, not every day.
- Avoid fertilizer burn by fertilizing only after plants are established.
- Do not soak plants in water more than 1 hour!
- Plants orders shipping to CA, OR, WA and HI will be charged a $15.00 fee for phyto-sanitary inspection.
- From Mid-May on, (depending on seasonal weather) orders shipping to states with a 4 or 5 Day ground transit time from MA will automatically be upgraded to 3DAY expedited shipping so that plants will arrive in optimal condition. This will be reflected in shipping charge.
- All plants are dormant, bare root, and ship from our Massachusetts nursery.
- We do not ship online orders outside the US.
- We use Federal Express as our standard shipper
- For large commercial orders, we offer various methods of Truck Shipments
