Planting & Care Guide

Ideal Location

Select a site with full sun to partial shade, ensuring at least 6 hours of direct sunlight daily. The narrow, upright habit works well along fences, narrow borders, or as a focal point in small gardens. Provide protection from strong winds to prevent foliage scorch.

Watering

Water thoroughly after planting to establish roots, then maintain moderate moisture. Once established, ‘Red Pillar’ tolerates brief dry spells but will perform best with consistent watering during prolonged drought. Avoid waterlogged soils to prevent root rot.

Pruning & Maintenance

Minimal pruning is required. Remove any dead, damaged, or crossing branches in late winter before new growth begins. To maintain a tight columnar shape, lightly trim side shoots after flowering. Avoid heavy cutting back, as this can reduce flowering and berry production.
