The Blackberry Triple Crown is a thornless, vigorous-growing variety known for its large, juicy, and sweet berries. This trailing plant requires support and thrives when trained on a trellis. It produces high yields of delicious blackberries in mid to late summer. Expect fruit within two years of planting. After harvest, prune old canes to the ground, leaving 5 to 8 new canes per plant. In winter, trim and train the canes for optimal growth. Hardy and disease-resistant, Triple Crown is an excellent choice for home gardens and berry enthusiasts.
