Growth

Culture: Space 36-48" apart. Propagate from cuttings. Plant your holly in early spring , before new growth begins and mulch with a 2- to 4-inch layer of wood chips , sawdust, pine needles , ground bark or other coarse material to keep the roots cool and moist.

Soil: Requires well-drained, slightly acid, fertile soil.

Sunlight: Sun Exposure: Sun to partial shade. Although semi-shade is preferable in midsummer, the more light it has the more dense its foliage will be.

Moisture: Water Requirements: Keep the soil moist during the summer growing season , but allow it to dry somewhat in early fall to allow the new growth to mature enough to resist winter damage.

Temperature: Cold Hardiness: 7a, 7b, 8a, 8b, 9a, 9b, 10a, 10b, 11. (map)
