These large, sweet, aromatic blackberries may run away from the competition once they begin appearing in supermarkets around the country. Triple Crown is the newest thornless blackberry from the Agricultural Research Service's Fruit Laboratory in Beltsville, MD. The berry is named for its three crowning attributes - flavor, productivity and vigor. Triple Crown ripens from about July 10 to August 10. The plants yield large, glossy black fruits that are pleasantly firm and able to withstand the rigors of shipping. Attractive and flavorful, it ripens later than the popular "Hull Thornless" blackberry and a week or so earlier than another widely planted berry, "Chester Thornless." Triple Crown berries are larger than both of these other commercially grown varieties, and should help ensure that berry farmers, owners of pick-your-own operations and backyard gardeners have a constant supply of big, flavorful thornless blackberries throughout the ripening season. Plants can be trellised or grown upright and pruned to a height of about 42".

Why Buy From Indiana Berry
 
 
Information 
Raspberry & Blackberries 
Both members of the genus Rubus, are collectively known as brambles. All brambles have a perennial root system which produces canes that are either biennial (grow for 2 years) or annual. During the first growing year, the canes are vegetative and are known as primocanes. In the second growing season, the canes become reproductive and bear fruit. Following fruiting, these 2-year-old canes, now called floricanes, die. At the same time, the bramble plant is also producing new primocanes. Under good care, the plant will normally grow and bear fruit for ten years. 
 
Selecting a planting site 
The planting site should receive full sun and have good air drainage. Brambles should not be grown in an area in which tomatoes, potatoes, eggplant, peppers or other crops susceptible to Verticillium wilt have been grown in the past 3-4 years. To avoid getting diseases from wild brambles, all wild brambles within 600 feet of your planting should be removed. Heavy or poorly drained soil should be avoided as bramble roots cannot tolerate a water saturated soil condition. Even areas that pond after it rains should be avoided. You should prepare your bramble site at least one year prior to planting. Work to build up organic matter and eliminate perennial weeds. A pH of 5.5 to 6.5 is desirable and the pH should not be below 5.5 or above 7 as serious problems will arise. Contact a fertilizer supplier or your County Extension Office for testing procedures and to determine the best way to amend your soil. 

How to plant your brambles 
Brambles should be planted on deep, well-drained loamy soils. They can be grown on sandy soils if irrigated. Ninety percent of the bramble root system is in the top 20 inches of the soil-so proper fertilizer and an ample supply of water is important. Set your plants in trenches large enough to contain the roots without crowding. Separate the roots in half and spread out on both sides of the cane. Set all brambles one inch deeper than they were in the nursery. You can determine the proper depth by the dark brown color line on the cane.  
Blackberries -Erect: Should be planted 6 to 8 ft en bewteen rows and 3 ft apart in between each plant.
Blackberries - Trellising: Should be planted 
6 to 8 ft in between the rows and 6 to 10 ft in between each plant.  Cut cane off at the ground level at time of planting. Prune off the top 3"-4" of the new shoots when they are about 24" high for black and 30" for purple. This topping should be done several times during the season. Remove the fruiting canes immediately after harvest. Carry from the field and burn to minimize disease problems.  The roots should only be covered with approximately 2" of soil. Be sure to press dirt firmly about the roots and water well to prevent air pockets. If the weather is dry, put on a light straw mulch. Blackberry roots are particularly sensitive to sunlight so it is very important to keep the root covered as much as possible while plants are out of the ground and if possible, plant on an overcast day. If there are any wild brambles growing around or near your new planting, they should be dug up and destroyed to prevent the possibility of their carrying diseases. 
 
Fertilize 
Apply 3-5 days after planting, use 1 cup per 10 feet of row, spread evenly with a 12" circle around the plant but no closer than 6" from the cane.

2nd Year apply 1/2 cup per 10 feet of row in the spring when new growth starts and again after harvest.

3rd Year apply 3/4 cup per 10 feet of row in the spring when new growth starts and again after harvest. 
 
Irrigation 
Ample amounts of water are needed for a healthy bramble planting, but never standing water. Newly planted plants should be watered well. Producing fields need up to two inches of water per week. This is especially true during fruit development and up to harvest. The use of mulch can help maintain and moderate fluctuations in available moisture but may increase your chances of developing root disease. Therefore we do not recommend using mulch after the first year.
 
Pruning 
Blackberries:
Erect - When blackberry primocanes (1st-year growth) reach about 36 inches, tip them to stimulate lateral branching. Immediately after fruiting remove floricanes at ground level and burn. In early spring, remove any dead or damaged canes and thin remaining canes leaving 5-6 per linear row. Prune laterals back to approximately 12' or a pencil diameter. 
Trailing - tip primocanes when they reach 5' (midsummer) and attach to a trellis, In early spring, remove any dead or damaged canes, and prune laterals back to approximately 12" or pencil diameter. Immediately after fruiting, remove floricanes at ground level and burn. Select the best 6-8 primocanes per linear row and attach to a trellis. 
Anthrocnose Control 
Where good sanitation is used (old fruited and infected canes are removed from the field), Anthracnose may not be a problem, especially on red raspberries. Where cane diseases are a problem, primarily black and purple raspberries, Lime Sulfur is very important. Lime sulfur is recommended for use on brambles as a delayed-dormant application in early spring (when buds show 1/4-inch green), it can label. If applied later in the season (after 1/4-inch green), it can cause severe damage to leaves and young canes. Lime sulfur is recommended for control of the cane-infecting fungi (anthracnose, cane blight, and spur blight). The delayed dormant application in spring is intended to eliminate or reduce the overwintering inoculums for these diseases on canes. Lime sulfur has a bad smell (rotten eggs) so there can be a problem spraying it around your neighbors. In addition, lime sulfur is very caustic. It is harmful to machine parts, paint (especially on cars) and sprayers. Special care should be taken to avoid drift and proper protective clothing should be worn by the applicator. 

Advantages of raised beds 
Medium to heavy soils often lack the proper drainage needed to successfully grow brambles. as Phytophthora Root Rot, a soil-borne fungus is commonly associated with poorly drained locations. raised beds can be a positive cultural step for control of the disease. Results of experiments show an 87% increase in yields on raised bramble beds. Raised bed production has long been considered an important cultural method for improving soil drainage. Even efforts for an 8-10" bed will be worth the investment. Research has shown, raised beds are an important step for increasing yields in Phytophthora susceptible bramble varieties.

Sam's Tip:
Gardeners in northern climates (Zones 3-5) have had success growing summer bearing blackberries by planting trailing varieties.  Remove the canes from the trellis in the fall and lay them flat on the ground.  Cover them with a thick layer of straw mulch and provide a windbreak to create a thick cover of snow to protect the canes from winter damage.  Re-trellis the canes in the spring.  This method has been successful on a regular basis.  In my opinion, this is too much work for commercial growers.
