How to Grow Apache Thornless Blackberry

Soil, care & harvest

Prepare your soil by amending it to reach a pH between 5.5 and 6.8 for optimal nutrient uptake. As a perennial cane fruit, you should plant bare-root canes or start seeds indoors about 2 to 4 weeks before the last frost date in cool-season regions. If sowing from seed, press them gently into the soil at a depth of roughly half an inch. Expect germination to take anywhere from 14 to 28 days.

Space your plants 3 to 4 feet apart to ensure good air circulation and room for cane development. Install sturdy trellis support immediately, as these vigorous canes require guidance to grow vertically. Water consistently to provide 1 to 2 inches per week, increasing frequency during fruit development. Apply a layer of mulch around the base to retain moisture and suppress weeds, while feeding regularly with balanced fertilizer.

Watch for spider mites, aphids, cane borers, birds, and Japanese beetles; use row covers or hand-picking to manage them. Prevent diseases like orange rust and crown gall by ensuring good airflow and avoiding overhead watering. Harvest ripe blackberries in late summer when they are fully dark purple and easily detach from the stem. This variety produces fruit annually once established.
