What Juniper is
Juniper grows as a perennial and reaches around 60 feet at maturity. It blooms white in spring. It's also deer-resistant.
How to grow Juniper
Juniper grows in USDA zones 4 through 9. Juniper does best in full sun — at least 6 hours of direct sun a day.

Plant it right
Set juniper in full sun with well-drained soil.
Match the soil
Pull a soil test from your local Extension lab to confirm pH and drainage match juniper's needs before planting.
Water steadily
Keep the root zone evenly moist through establishment. Match watering to the plant's drainage preference and your local rainfall.
Shape it while it is young
Prune juniper only to remove dead, damaged or crossing branches while it is young; it is grown for its form, not a harvest, so little more is needed once it settles in.
Where Juniper thrives
Juniper is hardy across USDA zones 4 through 9. Zone is only the starting point, though: the soil pH, drainage, and frost dates on your specific land decide how well it actually does.
A USDA zone is a 10°F band of average annual extreme winter minimum, so zones 4–9 spans average winter lows from -30°F to 30°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 33 outright and splits 18 more down the middle — and which side of that line your land sits on changes the answer.

Where Juniper stands, state by state
Juniper is rated for zones 4–9 — a cold floor USDA puts at -30 to -20°F. Across the 50 states and DC, 33 sit fully inside that band, the line runs through 18 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

What grows around Juniper
Good to know
Juniper isn't classified as a notable pollinator plant in our data — pair it with high-value bloomers nearby to feed bees.
Your land is one point inside Juniper's range
This page resolves to the species. Your state page draws the county line, and a report reads the parcel — the soil pH, drainage, sun, and frost dates on your exact ground, which no species average can see.

How we know this about Juniper
The figures above are cited per row, not per site: the pH band names this plant’s own source column, the three temperature figures each carry their own, and days-to-maturity cites the publication that actually lists it. All of it comes from the Growable Ground Plant Database — a compilation over FAO ECOCROP, USDA PLANTS, and university Extension sources, published openly with per-field provenance.

Frequently asked questions
Can I grow Juniper in my zone?
Juniper grows in USDA hardiness zones 4 through 9 (Rated hardy to zone 4a by NC State Extension Gardener Plant Toolbox; USDA PLANTS Database lists -33 °F, converted to zone 4a, checked Oct 2026. Ceiling: not verified.). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.
When should you plant Juniper?
Set juniper out in early spring or fall while it's dormant, so the roots establish before the heat of summer. Your local last-frost date — which a Growable Ground report pulls for your exact address — sets the precise window.
How much sun does Juniper need?
Juniper needs full sun — a spot that catches at least 6 hours of direct summer sun a day. In more shade it still grows, but usually gives a smaller, later crop. The catch is that a yard rarely gets even light everywhere — a fence, the house, or one tall tree can quietly take those hours. A Growable Ground report reads the real sun-hours across your land, canopy and buildings included, so you can pick the brightest bed before you plant.
What soil does Juniper need?
Specific pH data for juniper is pending. A soil test from your local Extension lab confirms what your site needs.
Does Juniper attract pollinators?
Juniper isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
