Planting & Care

Where to Plant

  • Sunlight: This evergreen thrives in full sun to partial shade, needing at least 4 to 6 hours of direct light daily. While it handles shade well, planting it in more sun results in a tighter, denser ball shape and faster growth.
  • Soil: These hollies love acidic, moist soil that mimics their natural woodland habitat. If you have heavy clay that stays gummy, mix in compost or peat moss to improve drainage and lower the pH level for healthier green leaves.

Watering Requirements

During the first year, keep the soil consistently moist to help the roots settle into their new home. Once established, Gem Box is quite adaptable to wet areas but needs regular deep watering during summer dry spells to prevent the lower leaves from thinning out. If the soil dries out completely, the plant may experience stress that leads to slower growth and a less compact appearance.

Pruning Tips

Because this holly produces flowers on new wood, the best time to prune is in early spring before the fresh growth begins. Think of it like a light haircut to maintain its natural rounded shape; simply shear the outer tips to encourage the plant to branch out and stay "full" from top to bottom. Avoid heavy pruning late in the summer, as this can stimulate soft growth that won't have time to harden before the first frost.

Fertilizer Needs

Apply a balanced fertilizer designed for acid loving plants once in early spring as the new buds begin to swell. This provides the necessary nutrients for that signature dark green foliage throughout the growing season. Avoid using high nitrogen fertilizers in late autumn, because pushing new growth right before winter makes the plant vulnerable to cold damage and "winter burn" on the leaves.

For a solid low hedge, plant them 1 - 3 feet on center. You'll measure from the center of one shrub to the center of the next. As your budget allows, plant them closer together. They'll fill in faster for you! You can also try a staggered zig-zag to create a mass planting on a slope or a large bare patch. The plants will grow to create a low-maintenance groundcover.
