Low-Maintenance Evergreen Beauty All Year Long
A Scaled-Down Version of America’s Favorite Privacy Tree
Thuja ‘Junior Giant’ is a modern improvement of the classic Green Giant Arborvitae — offering the same lush green foliage and quick growth in a smaller, easier-to-manage size. Reaching a mature height of 15–20 feet with a narrow 5–6 foot spread, it’s the perfect choice for residential yards, pool areas, driveways, and property borders where full-sized evergreens would overwhelm the space.
Junior Giant’s dense, layered branches form a solid privacy screen, even when planted close together, providing homeowners with year-round coverage that stays tidy and uniform without requiring constant pruning.
Ideal for Suburban and Urban Landscapes
Its naturally pyramidal form adds structure and evergreen texture to any garden style — from modern minimalist landscapes to traditional suburban hedges. Junior Giant Arborvitae thrives equally well as a single specimen tree, evergreen accent, or continuous living fence. With its smaller footprint, you can enjoy the same sense of seclusion as Green Giant without crowding your yard or those of your neighbors.
Tough, Adaptable, and Easy to Grow
Junior Giant grows well in a wide range of conditions — from full sun to light shade and in almost any well-drained soil. Once established, it’s exceptionally drought-tolerant and resists common pests and diseases. Its hardy constitution makes it a go-to evergreen for homeowners looking for beauty and reliability with minimal effort.
Even better, it’s deer-resistant, meaning it maintains its lush form year after year without unsightly browse damage.
A Lush Evergreen Privacy Tree With Four-Season Appeal
The soft, feathery foliage of Junior Giant remains rich green throughout all four seasons, providing texture and color even in the bleakest winter months. Its upright form makes it a beautiful natural backdrop for flowering shrubs, ornamental grasses, or perennial borders.
Whether planted as a property divider, windbreak, or evergreen foundation element, this arborvitae is a long-term investment in privacy, curb appeal, and landscape design.

How to Care for Junior Giant Arborvitae
Be sure to read about the recommended care instructions to keep your Junior Giant Arborvitae plant healthy and thriving for years to come!
How should I plant Junior Giant Arborvitae?
Dig a hole twice as wide as the root ball but only as deep. Position the tree so the top of the root ball sits slightly above ground level. Backfill with native soil mixed with compost and water thoroughly to remove air pockets. For a privacy screen, plant trees 5–6 feet apart center-to-center for a seamless hedge or 8–10 feet apart for defined spacing.
How often should I water Junior Giant Arborvitae after planting?
Water deeply once or twice a week during the first growing season. Keep soil consistently moist but not soggy to encourage deep root growth. After establishment, reduce watering frequency — Arborvitae are drought-tolerant, but during hot, dry periods, occasional deep watering will maintain their vibrant green color
When should I fertilize Junior Giant Arborvitae?
Feed in early spring with a slow-release balanced fertilizer (10-10-10 or similar). Avoid high-nitrogen lawn fertilizers near the root zone. You can also amend the soil with compost each year to support steady, healthy growth and strong root development.
When and how should I prune Junior Giant Arborvitae?
Minimal pruning is needed. Trim lightly in late spring or early summer to shape or remove stray branches. Avoid cutting into old wood — Arborvitae do not regenerate from bare stems. For formal hedges, shear lightly once yearly to maintain uniform height.
