Skinny Blue Genes Spruce
An Ultra-Narrow Blue Column of Fine Needles
Skinny Blue Genes Spruce (Picea glauca 'Skinny Blue Genes') is a remarkably narrow, slow-growing relative of the dwarf Alberta spruce, with fine powder-blue needles packed onto a tight, pencil-slim column. Reaching about 8-12 feet tall but only 1-2 feet wide, it is a unique vertical accent for the tightest spaces and modern plantings.

Skinny Blue Genes Spruce Uses in Minnesota Landscapes
Ultra-Narrow Accent
At barely 2 feet wide, it adds blue vertical structure where nothing else fits.
Containers & Pairs
Striking in tall containers or matched pairs at an entry.
Best Time to Plant Skinny Blue Genes Spruce in Minnesota
Spring through early fall all work, but late August through mid-September is ideal, giving roots time to settle before the ground freezes. Water deeply once a week the first season and mulch to hold moisture.
Skinny Blue Genes Spruce Uses in Minnesota Landscapes
Ultra-narrow vertical accent
At a remarkable 1–2 feet wide, Skinny Blue Genes is about as narrow as a spruce gets — a powder-blue exclamation point for flanking a doorway, marking a corner, or adding height to a tight perennial bed in Edina, Plymouth, or Wayzata.
Columnar screen for the tightest spaces
Its pencil-thin form lets you build a blue privacy column where nothing wider could fit. Plant 2–3 feet apart for a slim living screen along a fence line or between closely spaced houses in Minneapolis and St. Paul.
Containers and modern landscapes
The slow growth and skinny profile make it a striking container or entry-pot evergreen, and a natural fit for clean, contemporary plantings where vertical lines matter.
Four-season winter interest
The fine powder-blue needles hold their color and crisp vertical form through five months of Minnesota winter, giving the landscape year-round structure in minimal space.
Best Time to Plant Skinny Blue Genes Spruce in Minnesota
For evergreens, the ideal window is late August through mid-September, giving roots time to establish before the ground freezes and before winter wind can dry the needles. Spring (late April–May, after the ground thaws) is the second-best option. Avoid summer planting when possible — heat and dry wind stress new evergreens. Never plant after mid-October or before late April, when frozen ground and frost-heaving kill new roots.
How to Plant Skinny Blue Genes Spruce
- Dig wide, not deep — 2–3x the root ball width, the same depth as the ball. Heavy clay benefits from an even wider hole.
- Check for clay hardpan — if water pools in the hole, break through the clay layer or mound-plant to improve drainage.
- Backfill with native soil mixed with 20–30% compost; don't create a pure-compost "container" the roots won't leave.
- Spacing — 2–3 feet apart for a narrow columnar screen; 4+ feet for individual accents.
- Water basin — build a 3–4 inch ring around the planting to direct water to the roots. Flatten or remove it before winter to avoid ice damage.
- Mulch — 2–3 inches of shredded bark or wood-chip mulch, kept 2 inches away from the trunk. Do NOT use gravel mulch in Minnesota — it doesn't insulate.
Watering Skinny Blue Genes Spruce in Minnesota
First Year Watering Schedule
- Weeks 1–2: Every 1–2 days, deep and slow (15–25 minutes)
- Month 1–2: Every 3–4 days
- Month 3–6: Every 5–7 days during active growth; less if rainfall is adequate (Minnesota averages ~3 inches/month June–August)
- Stop watering 2–3 weeks before ground freeze (typically late October in the Twin Cities)
- Give one deep watering in early December if fall was dry — evergreens lose moisture through their needles all winter
After Year One
Established plants only need supplemental water during droughts (2+ weeks with no rain and temps above 80°F). Water deeply and infrequently — every 7–14 days during dry spells, soaking to 6–8 inches depth. Container plants dry faster, so check them weekly in summer.
Will Skinny Blue Genes Spruce survive a Minnesota winter?
Easily. As a white-spruce selection it's hardy to roughly -40°F (zone 3), so a Twin Cities winter is no challenge. Water deeply in late fall and keep the root zone mulched the first year.
How narrow is it really?
Just 1–2 feet wide at 8–12 feet tall — one of the skinniest spruce you can plant. That's the whole appeal: vertical blue color in almost no horizontal space.
Is it deer-resistant?
Strongly. Deer almost always pass over spruce — the stiff needles are unpalatable — making it a dependable choice for high-pressure deer suburbs like Minnetonka, Wayzata, and Eden Prairie.
Does it need full sun?
Yes — give it full sun (6+ hours) for the densest growth and best blue color. It tolerates light shade but grows looser and greener with less light.

How Many Skinny Blue Genes Spruce Do I Need?
For a pencil-slim columnar screen, space plants 2.5 feet on center (mature width is only 1–2 feet, so tight spacing is correct):
| Screen Length | Plants Needed (2.5-ft spacing) |
| 10 feet | 5 |
| 15 feet | 7 |
| 25 feet | 11 |
For accents, a matched pair flanking a door or gate is the classic move; in beds, plant singles or a staggered trio 4 feet apart for a rhythm of blue columns.
Skinny Blue Genes Spruce Season-by-Season in Minnesota
- Spring: Fresh powder-blue needles flush in May, brightening the whole column while it adds its modest 3–6 inches.
- Summer: The tight, fine-needled column stays crisp through heat with no shearing — vertical blue structure in almost zero footprint.
- Fall: Holds full color and density as perennials around it die back, suddenly becoming the backbone of the bed.
- Winter: A slim blue exclamation point against the snow for five months; its narrow profile sheds snow loads that splay wider evergreens.

Is Skinny Blue Genes Spruce Right for Your Yard?
Choose it if you have a full-sun spot measured in inches rather than feet — doorways, fence lines, narrow side yards, modern beds — and you want deer-proof blue color year-round. It's not a fit if you need real privacy mass or fast height: at 3–6 inches a year and 2 feet wide, it's an accent and slim screen, never a windbreak.
