Growth Habit and Form
Upward Column Development
Degroot's Spire Arborvitae grows steadily upward with minimal lateral spread. Tight branching creates a uniform spire shape that remains neat through maturity.
Prone to Minimal Drift
Because the plant maintains a narrow profile, it rarely encroaches on neighboring structures. This reduces long term pruning demand compared to broader evergreens.
Site Selection and Planting
Sunlight and Airflow Needs
Choose a location with at least six hours of direct sun daily for strongest stems and deepest green color. Slight morning sun helps dry dew and lowers disease pressure.
Spacing and Soil Preparation
Dig a hole as deep as the root ball and two to three times wider. Amend the backfill with compost to improve drainage while preserving firm soil contact around the roots.
Care and Seasonal Maintenance
Watering Schedule and Winter Prep
Water thoroughly during the first two years, especially before ground freeze. Established plants tolerate brief dry spells but perform best with consistent moisture during heat waves.
Light Pruning for Shape
Trim only to remove damaged stems or correct minor shape deviations. Shearing in late winter or early summer encourages dense outer growth without sacrificing the natural outline.
Landscape Integration and Long Term Value
- Use as a vertical accent near entries without blocking doors or windows.
- Pair with low spreading shrubs to create layered depth in small gardens.
- Install with drip irrigation for consistent moisture during establishment.
- Monitor for pests annually and prune only to remove broken or crossing branches.
- Select this cultivar when space is limited but year round structure is desired.
FAQ
Reader questions
How quickly does Degroot's Spire Arborvitae establish height?
Under optimal conditions, this arborvitae adds 6–12 inches of height per year, reaching its mature range in seven to ten years while staying within its narrow footprint.
Can it survive harsh winter wind in exposed areas?
Yes, its dense branching and moderate cold tolerance make it suitable for wind corridors, though supplemental watering before the ground freezes helps prevent desiccation.
Is this cultivar resistant to common arborvitae pests?
It shows good resilience against bagworms and tip blight when planted in healthy soil, though routine inspections help catch any early infestations quickly.
Will the strong vertical form fit beside a fence?
Because the spread stays under 4 feet, Degroot's Spire Arborvitae can safely border fences when given at least 3 feet of clearance for mature growth and air movement.
