Soil: Moist but well-drained soils are best. Dry soil in fall and winter (before the ground freezes) will increase the chance of winter burn.
Light: Full sun (6+ hrs/day) to part shade (4-6 hrs/day).
Water: Average - do not overwater, as holly can readily suffer root rot.
Space: min. 5' apart. Plant this male variety within 50' of the female plants.
Fertilizing: If desired, fertilize in early spring, once the ground has thawed, with a granular rose fertilizer. A second application may be made in late spring/early summer as well.
Winterizing: 2-3" of shredded bark mulch is important to protect the shallow roots and minimize water loss. Do not allow plants to enter winter "thirsty" – dry soil during cold, windy weather is the main cause of leaf browning or even the plant dying.
Maintenance: None required. Because it does not set fruit, can be trimmed after flowering if desired.
