Frequently Asked Questions

What are the best growing conditions for Wiltoni Juniper?

Wiltoni Juniper thrives in full sun and requires well-drained soil. It performs well in poor, sandy, rocky, or dry soils and is extremely drought-tolerant once established. It’s perfect for slopes, rock gardens, coastal areas, and erosion control.

How large does Wiltoni Juniper grow?

This is a very low-growing, fast-spreading evergreen, typically growing 4–6 inches tall and spreading 6–8 feet wide. Its ground-hugging habit makes it one of the best choices for dense, weed-suppressing coverage in sunny areas.

What does the foliage of Wiltoni Juniper look like?

Wiltoni features silvery-blue, scale-like foliage that maintains its color year-round. In cold weather, it often develops purplish tones, adding a subtle but attractive winter interest. The soft, trailing branches create a carpet-like effect across the ground.

Is Wiltoni Juniper deer-resistant?

Yes—Wiltoni Juniper is highly deer-resistant. Its aromatic foliage and dense, scratchy texture make it unappealing to deer and rabbits, making it a reliable choice in landscapes with wildlife browsing pressure.

Does Wiltoni Juniper require pruning?

Not at all. Wiltoni Juniper is extremely low-maintenance and holds its form without pruning. You can trim lightly in early spring to manage spread or define edges, but heavy pruning is rarely needed. Avoid cutting into old wood, which may not recover.
