Plant Care & Growing Tips

Proper care is essential for maximizing the yield and health of your Prime Ark Horizon blackberry plants. These robust plants thrive with attention to their specific needs. When selecting a site, choose an area that receives full sun, meaning at least 6-8 hours of direct sunlight per day. Good air circulation is also important to prevent fungal diseases. Blackberries prefer well-draining, slightly acidic soil with a pH between 6.0 and 6.5. Amend heavy clay soils with organic matter such as compost or aged manure to improve drainage and fertility. Ensure the planting bed is free of weeds before planting your blackberry starter plugs.

Watering should be consistent, especially during dry periods and when the plants are fruiting. Aim for about 1 inch of water per week, either from rainfall or irrigation. Avoid overhead watering if possible, as this can encourage foliar diseases; drip irrigation or soaker hoses are ideal. Fertilize in early spring with a balanced granular fertilizer, following product instructions carefully. Pruning is crucial for primocane-fruiting blackberries like ‘Prime-Ark Horizon’. For the primocane crop, canes that produced fruit should be cut back to the ground after fruiting in late fall or early winter. For the floricane crop, prune out only the spent floricanes after they fruit in summer, leaving the new primocanes to produce the fall crop. Support systems like trellises or wires can help manage the canes and keep the berries off the ground, ensuring a healthier and more accessible harvest from your Rubus Horizon.
