Pruning And Training Blackberry Plants

Pruning and training blackberry plants are crucial for maintaining plant health and maximizing fruit production. Proper pruning and training techniques also help with disease prevention and make harvesting easier.

Pruning

Blackberry plants have a biennial growth habit, meaning that they produce canes that live for two years. Understanding this growth habit is essential for effective pruning.

In the first year, the primocanes (first-year shoots) grow vegetatively and do not bear fruit. These canes are usually green in color. It is important to train and support these canes during their first year of growth.

In the second year, the primocanes that grew the previous year become floricanes (fruiting canes). These canes have a brown bark and produce fruit. After fruiting, they die back and should be pruned to make way for new primocanes.

Pruning should be done in late winter or early spring before new growth begins. Remove any damaged, dead, or diseased canes at ground level. Thin out the remaining canes, leaving about 5-7 of the healthiest and most vigorous canes per plant. This will ensure optimal air circulation and light penetration.

Training

Blackberry plants are often trained onto trellises or support systems to provide them with structural support and to make harvesting easier. There are several training methods for blackberries, including the single-cordon, the fan system, and the hedge system.

The single-cordon method involves training a single main cane along a wire or trellis. This system works well for erect blackberry varieties. Remove any lateral shoots that emerge from the main cane.

The fan system is suitable for trailing blackberry varieties. Train the canes to grow outward from a central point, forming a fan shape. This method helps maximize sunlight exposure and airflow.

The hedge system is commonly used for semi-erect and trailing blackberry varieties. Several canes are allowed to grow together in a row, forming a hedge-like row. Canes should be trained to grow upward and secured to a trellis or support posts.

Choose the training method based on the growth habit of your blackberry variety and the available space in your garden. Regularly check the canes and tie them to the trellis or support system as needed.
