Planting & Care Guide
Ideal Location
Plant ‘Red DJ’ in a spot that receives at least 4–6 hours of sunlight daily. While it tolerates part shade, full sun intensifies foliage color. Ensure the site has well-draining soil; avoid waterlogged areas to prevent root rot.
Watering

Pruning & Maintenance
Minimal pruning is required. To maintain shape, prune immediately after flowering in late spring. Remove any dead or crossing branches, and thin interior growth for improved air circulation. Mulch around the base to conserve moisture and suppress weeds.
