Quercus phellos. Also called Peach oak.
Plain-English notes for homeowners, plus field notes for tree crews. General guidance only: for one specific tree, have a local insured pro look at it.
Willow Oak at a glance
| Height | 40-75 ft |
|---|---|
| Spread | 30-50 ft |
| Growth rate | Medium |
| USDA zones | 5-9 |
| Lifespan | typically 50-100+ years |
| Type | Deciduous |
| Native range | Southeastern and mid-Atlantic United States, from New Jersey south to northern Florida and west to east Texas and the Mississippi Valley. |
| Roots | Mostly fibrous and fairly shallow, with a wide spread. Roots are easily hurt by trenching, grade changes and soil piled over them. The tree handles wet soil well. |
| Wood | Hard, heavy red-oak-group wood. It makes good firewood once well seasoned, which typically takes a year or more. |
| Storm risk | mediumWood is fairly strong, but old trees often have decay in large limbs and the trunk. Heavy crowns on city lots can lose limbs or fail in saturated soil during strong wind. |

For homeowners
Caring for a willow oak
Best time to prune
Late fall through winter while the tree is dormant. Remove dead and crossing limbs early and keep one main leader on young trees.
Avoid pruning
Avoid pruning from spring through mid-summer when oak wilt beetles may be active in areas where oak wilt is present. Do not top the tree.
More on timing: when to prune trees.
- Protect the ground under the whole canopy from digging, parking and soil piled up against the trunk.
- Water deeply during long dry spells, especially for young trees.
- Have large limbs over the house or driveway checked by an certified arborist every few years.
- Rake or mulch the narrow leaves in fall; they do not form a thick mat like some broadleaf leaves.
Safety first
Do not climb a tree or use a chainsaw on storm-loaded or broken wood. If a tree or limb is touching power lines, stay away and call the utility. If someone is in danger, call 911. For anything big, hire a local insured pro: read how to hire a tree service and is my tree dangerous?

For tree crews
Field notes: working on willow oak
- 1Check large limbs and the trunk for hollows and decay before climbing.
- 2Expect dense, hard wood that dulls chains faster than softer species.
- 3In oak wilt areas, prune in the dormant season and follow local guidance on fresh wounds.
- 4Look for girdling roots at the base on older street-planted trees.
Removal notes
Large street-size trees often need climbing or a bucket truck and piece-by-piece lowering because of wide, heavy limbs. Check for decay before any climbing. Stump grinding is usually needed because the root flare is large. Get a quote.
Wood
Hard, heavy red-oak-group wood. It makes good firewood once well seasoned, which typically takes a year or more.

Willow Oak: common questions
Why is it called a willow oak?
The leaves are long, narrow and have smooth edges, so they look like willow leaves instead of the lobed leaves most oaks have.
How fast does a willow oak grow?
It typically grows at a medium rate, often around 1 to 2 feet a year when young and well watered. Growth slows as the tree ages.
Can a willow oak get oak wilt?
Yes. It is in the red oak group, which is the group most affected by oak wilt. Ask your state extension service whether oak wilt is in your area.
Is a willow oak a good street tree?
It is widely planted along streets in the South and mid-Atlantic because it handles city conditions and wet soil. It needs plenty of room, since it gets large.
How do I tell a willow oak from a water oak or laurel oak?
Willow oak leaves are narrow and about the same width along the whole leaf. Water oak leaves are wider near the tip, and laurel oak leaves are wider in the middle. An arborist can confirm.
When should I prune a willow oak?
Typically in the dormant season, late fall through winter. Dead branches that are a safety risk can be removed any time.
