Planting & Care

Where to Plant

  • Sunlight: This holly thrives in full sun for at least six hours to maintain its dense and mounded form. It accepts partial shade, but fewer hours of light will result in a more open and leggy growth habit.
  • Soil: Use moist and acidic soil rich in organic matter. If your soil is alkaline or heavy clay, add elemental sulfur or peat moss to lower the pH and prevent the leaves from turning yellow.

Watering Requirements

Check the soil daily during the first year and water whenever the top inch feels dry to the touch. Mature plants are quite adaptable to wet sites but will drop their lower leaves if left to dry out completely. Regular moisture is the secret to keeping this shrub looking full from the ground to the top.

Pruning Tips

Since this plant flowers on old wood, wait until after the spring growth has emerged to do any shaping. Use hand pruners to snip back long stems, which encourages the plant to branch out and stay thick. Think of it like a light haircut rather than a heavy buzz cut to preserve its natural rounded shape.

Fertilizer Needs

Feed your plants with a slow release fertilizer designed for evergreens once in early spring. Avoid applying high nitrogen products after mid summer because the resulting tender growth can be killed by early frosts. Providing nutrients early in the year supports the vigorous spring push and helps maintain the dark green leaf color.
