Triple Crown is named for its three attributes; flavor, productivity and vigor. This very hardy variety offers two other attributes; disease resistance and very large berries. Triple Crown ripens a bit after Apache has started producing. It also has a longer harvest period than Apache when adequate moisture and heat are present. Thornless blackberries ripens for about one month from end of July thru August. Hardy in Zones 5-10
Apache berries are the largest of all the thornless berries and are nice and sweet. Very productive Apache ripens mid to late June. Hardy in Zones: 5b-10. It has an erect, strong form at maturity, but I have noticed the young canes on 1 and 2 year old plants to be a bit trailing. It has nice, medium-large berries that get very sweet when fully ripe. Like all blackberries, best flavor of fruit occurs when it is a dull black.
Ouachita is a very popular variety. Ouachita, pronounced WAH-shi-tah, is a very upright growing, vigorous, thornless blackberry. It should be tipped when canes get to 48" tall, to make it sturdier and more productive. However, trellising or staking may be needed to keep a full crop from leaning towards the ground. Fruit quality is excellent. Berries are firm, sweet and about the same size as Apache. Fruit matures beginning in mid to late July. Hardy in zones 5-10.
Plants will be growing in 1 gallon tree pots and may be dormant depending upon when you receive them.
Blackberries (Thornless & Semi-erect)
Some type of trellis support is recommended and a 3-4 wire trellis works best for this type of plant. Tip 1st year canes when they reach 5 feet high in midsummer. Canes that fruited can be removed anytime after they have been harvested. Thin the remaining canes to 8 canes per running yard of row. If grown in a hedgerow, thin canes to 6-8 canes per hill. Wrap the laterals around the wires before Mid-September, before canes become woody and brittle.
Sometimes thornless blackberries are managed by tying them to a stake. In the staked-hill system, the canes are wrapped around a stake 2 inches in diameter, tied in 2 to 3 places, and cut off to the height of the stake at 5-6 feet above ground level. The plants are set 5-8 feet apart in every direction and restricted to a clump. This is an easy to maintain system and can be an attractive addition to the home garden landscape. A trellis or staking is highly recommended for the semi-erect, trailing blackberries in order to keep the fruit clean and minimize canes breaking.
