What Arborvitae is

Arborvitae grows as a perennial and reaches around 50 feet at maturity. It blooms in mid spring.

How to grow Arborvitae

Arborvitae grows in USDA zones 3 through 7. It needs about 400 hours of winter chill, which is why climate matters as much as soil.

  1. Plant it right

    Set arborvitae in full sun with well-drained soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.

  2. Match the soil

    Pull a soil test from your local Extension lab to confirm pH and drainage match arborvitae's needs before planting.

  3. Water steadily

    Keep the root zone evenly moist through establishment. Match watering to the plant's drainage preference and your local rainfall.

  4. Be patient, then harvest

    Prune annually while the tree establishes; fruit trees reward patience with years of harvest. Local Extension guides publish per-cultivar bearing-age tables.

Where Arborvitae thrives

Arborvitae is hardy across USDA zones 3 through 7. 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 37 spans average winter lows from -40°F to 10°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 23 outright and splits 25 more down the middle — and which side of that line your land sits on changes the answer.

Where Arborvitae stands, state by state

Arborvitae is rated for zones 37 — a cold floor USDA puts at -40 to -30°F. Across the 50 states and DC, 23 sit fully inside that band, the line runs through 25 more, and 3 sit outside it — and inside every split state, the same line runs on at county grain.

Too little winter chill rather than too much cold — a low-chill selection is what changes it. Each link is that state’s own growing hub.

State zone extents: USDA Plant Hardiness Zone Map (PHZM) 2023. A zone is a 10°F band of average annual extreme minimum temperature, so a state that splits the band contains the boundary — its own page draws the county line, and a parcel report resolves which side your land sits on.

What grows around Arborvitae

In rotation planning, arborvitae counts as a Other — beds recover best when other crops don’t follow each other in the same spot year over year. (Growable Ground derivation — crop-rotation group from botanical family)

Good to know

Good news for pet owners — arborvitae isn't known to be toxic to dogs or cats. (Source: ASPCA.)

Arborvitae isn't classified as a notable pollinator plant in our data — pair it with high-value bloomers nearby to feed bees.

How we know this about Arborvitae

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 Arborvitae in my zone?

Arborvitae grows in USDA hardiness zones 3 through 7 (USDA PHZM 2023). Zone is one factor — soil pH, drainage, and frost dates on your specific parcel also shape whether it takes.

When should you plant Arborvitae?

Set arborvitae 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.

What soil does Arborvitae need?

Specific pH data for arborvitae is pending. A soil test from your local Extension lab confirms what your site needs.

Does Arborvitae attract pollinators?

Arborvitae isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.

Is Arborvitae safe for pets?

Arborvitae is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
