Pin Oak

• Deeply cut, pointed lobes with bristle tips
• Strongly pyramidal shape; lower branches sweep downward
• Dead lower branches ('pins') persist inside the crown
• Small, round acorns with shallow caps

Native range

Native to bottomlands of the eastern United States, reaching only the far eastern edge of Kansas naturally. It has been planted statewide, well beyond the soils that suit it.

Soil

Needs acidic soil, below roughly pH 7.0. Kansas' alkaline clay locks up iron and the tree slowly starves — test your soil before planting one, not after.

Sunlight

Full sun

Drought & heat

Moderate drought tolerance, moderate heat tolerance.

Test your soil pH before planting one. Above about 7.5, expect chronic chlorosis — a bur oak, shumard oak, or chinkapin oak will be far happier in Kansas clay.

Shallower and more fibrous than most oaks, which makes it less drought-resilient here but also less of a threat to paving.

Sound wood and a strongly pyramidal form with good branch attachments. A healthy pin oak handles Kansas wind well; a chlorotic, declining one is a different tree entirely and sheds deadwood constantly.

Overall storm resistance: Good. Assessing damage after a storm

• Iron chlorosis

  Serious

  The defining problem for this species in Kansas. Leaves turn yellow between green veins, then brown at the margins, and the crown thins from the top. Treatment manages symptoms; it never fixes the soil.

• Oak wilt

  Serious

  A fungal disease fatal to red-oak-group trees, often within one season. Leaves drop while still half green. It spreads through root grafts between neighboring oaks as well as by beetles.

• Bacterial leaf scorch

  Serious

  Browning that begins at leaf margins in late summer, separated from healthy green tissue by a narrow yellow band. It recurs and worsens annually; there is no cure.

Best windowDormant season only — December through February. Never April through July.

Remove the persistent dead lower branches — the 'pins' — for clearance as needed. The timing rule is not optional: sap beetles that carry oak wilt fly from April through July, and a fresh cut on a red-oak-group tree in that window is an open door.

Reasonable near a home in eastern Kansas where soil pH allows it. In central and western Kansas, choose a bur, chinkapin, or shumard oak instead and skip the decades of chlorosis treatment.

• Chronic severe chlorosis with progressive crown dieback that treatment has not reversed
• Oak wilt confirmed by a lab — act quickly and sever root grafts to protect neighboring oaks
• Structural decay in the trunk above a target

Removal is a judgment call about risk, not a formula. A tree with one of these conditions over open lawn is a very different situation from the same tree over a driveway — and that judgment needs someone on site.
