CASTLE KEEP® Blue Holly

Zone: 5, 6, 7, 8 Exposure: Full Sun, Part Sun Height: 3-5' Width/Spread: 3-4'

Long a favorite during its evaluations, Castle Keep® blue holly has the classic good looks of this handsome evergreen but with soft-to-the-touch deep green foliage. Semi-dwarf rounded habit makes it a versatile choice for landscape. This is a female variety that will develop red fruit if a male pollinator like Castle Wall® holly is planted nearby.

Light: Needs full to partial sun exposure to grow robustly, but in warmer zones it appreciates protection from the harshest sunlight.

Soil: Requires acidic soil to thrive.

Water: Requires regular water, as its roots grow quite close to the soil surface. Mulch helps keep the soil moist.

Fertilizing: Regular fertilization isn’t necessary, but can be done in the springtime when the soil is workable.

Pruning: It’s best to avoid pruning, as flowers grow from old wood. If you need to do a few maintenance cuts, you can do so in the late winter or early spring.

Other: If you harvest a few branches in the winter, spread cuts around the plant to prevent obvious holes from forming. Avoid cutting any branches thicker than a pencil, as these wounds take a long time to heal. Female plants need a male pollinator to produce berries. Plant one male for every seven females, and be sure to position them within 50 feet of each other so they can get good cross-pollination.
