Sycamore is a tree, a long-term addition to the landscape. It's hardy across USDA zones 4 through 9 and shrugs off deer. It roots deep, which helps it reach moisture in a dry spell and open up tight soil as it establishes.

What Sycamore is
Sycamore grows as a perennial and reaches around 100 feet at maturity. It blooms red in spring. It's also deer-resistant.
How to grow Sycamore
Sycamore grows in USDA zones 4 through 9. Sycamore does best in part sun — at least 4 hours of direct sun a day — and soil from pH 3 to 10, on well-drained ground. It needs about 800 hours of winter chill, which is why climate matters as much as soil.

Plant it right
Set sycamore in part sun with well-drained soil. Many fruit trees need a second variety nearby to pollinate — check before you plant just one.
Match the soil
Sycamore prefers pH 3 to 10 (FAO ECOCROP). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.
Water steadily
Keep the root zone evenly moist through establishment. A 2–3 inch mulch layer holds moisture without waterlogging.
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 Sycamore thrives
Sycamore 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 Sycamore stands, state by state
Sycamore 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.

Growing guides for sycamore
In rotation planning, sycamore 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

Sycamore 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 Sycamore
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 Sycamore in my zone?
Sycamore grows in USDA hardiness zones 4 through 9 (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 Sycamore?
Set sycamore 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 Sycamore need?
Sycamore does well in partial sun — around 4 hours of direct sun, and it takes some afternoon shade in stride. That flexibility makes it a good match for a bed the house or a nearby tree shades for part of the day. A Growable Ground report maps how the sun actually falls on your land, hour by hour, so you can set it where the light lines up.
What soil does Sycamore need?
Sycamore prefers soil pH 3 to 10, on well-drained ground (FAO ECOCROP). Your report scores your parcel's actual soil against that using USDA SSURGO data.
Does Sycamore attract pollinators?
Sycamore isn't classified as a notable pollinator plant in our data. Pairing it with high-value bloomers nearby keeps bees and butterflies fed.
Is Sycamore safe for pets?
Sycamore is not known to be toxic to dogs or cats based on available data. Always supervise pets around new plantings. (Source: ASPCA.)
