Plant Care & Growing Tips
Caring for your Prime Ark Horizon blackberry live plant is straightforward, ensuring a bountiful harvest with proper attention. These plants thrive in conditions that mimic their natural habitat, requiring well-draining soil and ample sunlight. For best results, choose a planting site that receives full sun, meaning at least 6-8 hours of direct sunlight per day. Adequate sunlight is crucial for fruit development and overall plant health. Ensure good air circulation around the plants to prevent fungal diseases. When planting your blackberry starter plug, amend the soil with organic matter to improve fertility and drainage.
Watering is essential, especially during dry periods and when the plant is establishing and fruiting. Aim for consistent moisture, but avoid waterlogging the soil. A good rule of thumb is to water deeply once or twice a week, checking the soil moisture regularly. Blackberries prefer a slightly acidic to neutral soil pH (6.0-6.5). Fertilize in early spring with a balanced slow-release fertilizer designed for berries or fruiting plants. Pruning is key for productivity with this primocane fruiting blackberry. Since it’s primocane-fruiting, you can choose to prune all canes to the ground in late winter for a single, large fall crop, or selectively prune floricanes (canes that fruited in summer) after harvest to encourage new primocanes for a dual crop. The ‘Prime-Ark Horizon’ is best suited for USDA Hardiness Zones 6-9, so protecting it from extreme winter conditions in the lower end of this range might be necessary.
