How to Grow Yellowwood

Cladrastis kentukea · Zones 4-10

Yellowwood is a tree, a long-term addition to the landscape. It's hardy across USDA zones 4 through 10 and shrugs off deer. Its early summer flowers are a real draw for honeybees and native bees.

What Yellowwood is

Yellowwood grows as a perennial and reaches around 40 feet at maturity. It blooms white in early summer. It's also deer-resistant.

How to grow Yellowwood

Yellowwood grows in USDA zones 4 through 10. Yellowwood does best in part sun — at least 4 hours of direct sun a day — and soil from pH 4.8 to 7.5. It needs a growing season of at least 180 frost-free days and about 700 hours of winter chill, which is why climate matters as much as soil.

  1. Plant it right

    Set yellowwood in part 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

    Yellowwood prefers pH 4.8 to 7.5 (USDA PLANTS). A quick soil test from your local Extension lab tells you whether to add lime or sulfur to land in band.

  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 Yellowwood thrives

Yellowwood is hardy across USDA zones 4 through 10. 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 410 spans average winter lows from -30°F to 40°F (USDA PHZM 2023). Across the 50 states and DC, that band covers 38 outright and splits 13 more down the middle — and which side of that line your land sits on changes the answer.

Where Yellowwood stands, state by state

Yellowwood is rated for zones 410 — a cold floor USDA puts at -30 to -20°F. Across the 50 states and DC, 38 sit fully inside that band, the line runs through 13 more, and 0 sit outside it — and inside every split state, the same line runs on at county grain.

Yellowwood’s band covers part of each of these states — which side of the line your county sits on changes the answer, and each state page draws it.

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 Yellowwood

In rotation planning, yellowwood counts as a Legume — beds recover best when legume 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 — yellowwood isn't known to be toxic to dogs or cats. (Source: ASPCA.)

Yellowwood is a standout pollinator plant — high value to bees and other pollinators.

How we know this about Yellowwood

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 Yellowwood in my zone?

Yellowwood grows in USDA hardiness zones 4 through 10 (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 Yellowwood?

Set yellowwood 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 Yellowwood need?

Yellowwood 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 Yellowwood need?

Yellowwood prefers soil pH 4.8 to 7.5 (USDA PLANTS). Your report scores your parcel's actual soil against that using USDA SSURGO data.

Does Yellowwood attract pollinators?

Yes — yellowwood's flowers are a strong nectar and pollen source for honeybees and native bees.

Is Yellowwood safe for pets?

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